Everyone was very interested in Professor Wu's project, but after hearing the investment estimate, they were immediately speechless, and no one expressed interest in the project.

Professor Wu looked around and saw that although some people were interested, no one dared to respond, and he couldn't help but be deeply disappointed.

Under the background of the peak of petrochemical energy and the constraints of emission reduction, people are vigorously pursuing new energy, and the hottest field is solar energy.

The energy produced by the sun shining on the earth for one hour is enough for the world's current energy needs throughout the year. Because of this, the use of solar energy is seen as the ultimate way to get rid of dependence on oil. If solar energy can be used in a resource-saving way to obtain net energy profits, human beings can truly be called to have an inexhaustible source of energy.

At present, in the world, the utilization of solar energy technology has made rapid development, but the proportion of solar energy is far less than one percent of the world's total energy consumption, and the high cost is an important reason why solar energy is not widely used.

The solar cells used today are large. Silicon is mostly used as a material, because silicon is more efficient than other materials. However, silicon is a more difficult material to work with. In addition, the manufacturing process also requires a lot of water and energy, and the latest material to replace silicon is the photoelectric film, but the photoelectric film is not as efficient as silicon, and the same power generation requires more photoelectric film.

However when it comes to whether solar cells can. There is no clear answer to the question of generating net energy profits, i.e., when energy is produced more than energy is consumed, either now or in the future.

For now, manufacturing solar cells. The direct energy consumption is slightly lower than the energy it produces, so it looks like it can generate energy net profits.

But to solve the problem of solar energy utilization, the biggest problem is energy storage. Exist. Since sunlight only shines during the day, and there is not always sunlight during the day. If you want to rely entirely on solar energy, you have to find a way to store it. To date, scientists have not found a cost-effective way to store solar energy, and both methods have been developed, compressed air and battery storage, which are very expensive.

To date, the most successful photoelectric thin film technology is cadmium telluride. This technology could presumably bring the cost of solar power on par with the cost of existing electricity.

But thin-film technology relies on tellurium, which is the rarest in the world. It is used in memory chips, optical discs, and is used as a reinforcing agent for lead and copper. As long as thin-film technology is significantly improved, the demand for tellurium will continue to rise. Some geologists believe that tellurium will become scarce within two decades, even with current use.

Most tellurium comes. Since the refining of copper, but the price of energy has risen, the cost of copper mining has become more expensive, and the price of tellurium has also become more and more under upward pressure.

In short, while there is certainly room for development in the future, photovoltaics are still far from being widely used, at least in terms of thin-film technology and solar energy storage.

Although Professor Wu was very disappointed, Fan Wuxian had put some thought into this, but he didn't know where the current frontier position that could be used too much was, so it was difficult to say anything rashly, after all, he had a fight with a vice governor just now, and if he showed up again, it would inevitably attract more criticism.

However, he stopped talking, which did not mean that others had no idea what he had just said, so Boss Zhu called his secretary and asked him to do something and check the bottom of Top Company in detail to see how much of what Fan Wuxian said was to the point.

The secretary's work efficiency is quite high, that is, it took half an hour to put a more detailed digital information in front of Boss Zhu, after he turned a few pages, his face was very ugly, obviously this information has confirmed Fan Wuxie's accusation just now, Top Company is not a serious software company at all, but a leather bag company that circles money in the stock market under the banner of high technology.

After Boss Zhu finished reading it, he pushed the information to the side and motioned for Fan Heng to take a look as well.

Fan Heng was a little unnatural because of his son's performance just now, after all, many people at the scene knew the father-son relationship between the two, and seeing Fan Wuxian so blatantly make a deputy minister unable to come to the stage, he also muttered a little in his heart, and he didn't know where to start.

At this time, seeing that Fan Wuxi had settled down, Boss Zhu asked him to read a piece of information, and he was a little uncertain in his heart, but he always felt that Fan Wuxi basically didn't talk nonsense, since he attacked a company like this, then this company must not be an egg without seams!

Sure enough, Fan Heng glanced at it twice, and found that this was an investigation data for Top Company, and some of the above figures were compared, needless to say, it could prove that Fan Wuxie's fiercely worded statement just now was definitely not a lie.

"This matter-" After Fan Heng read the information, he returned it to Boss Zhu, but he didn't know how to speak.

"It's still right to say that there is no disease, for the sake of political performance, the local government is very bold." Boss Zhu said to Fan Heng with an unkind face, "With a company of this size, it can actually get strong support from the province, in addition to seeing the best problems, there is also the thirst of local officials for political performance, in order to get the motivation to move forward, do something that violates the basic principles, that is, it is easy to understand." ”

In fact, he has now thought clearly, in the current stock market, this kind of thing is not a minority, so one year of excellent performance, two years of loss, three years of ST, four years of delisting are happening all the time, the congenital defects of China's stock market have led to the occurrence of this strange phenomenon, the stock market operation system does not change, this kind of thing can not be avoided.

"Although it's right to be disease-free, I can't catch anyone now." Fan Heng thought for a while and said, "After all, if a company wants to expand, it needs financing, and after financing, it is expansion, and you have to leave enough time for others to develop before you can see whether this is a leather bag company or a real software company." ”

Boss Zhu nodded, also a little helpless, if you want to investigate the root of the problem, you should first investigate who put this company into the stock market in the first place, the company in this situation does not have the qualifications to be listed at all, but he went public, and it is very hyped, this is the problem.

Without the cooperation of the government and enterprises, this kind of thing would never have happened, but if it is carefully investigated, it is bound to be protracted, and every process of collecting evidence will be very difficult.

"Bastard!" Boss Zhu couldn't help but scold again, obviously angry in his heart.

Professor Wu has finished talking for a while, and an economist has gone up to talk about the current real estate development problem, and everyone is arguing very hotly, after all, this is the most closely related to the lives of ordinary people.

Seeing that everyone's attention was there, Fan Wuxian quietly came to Professor Wu's side, and then made a gesture of please, and the two of them walked to the corner next to them together, found a table and sat down.

"Is Mr. Fan interested in my project?" Professor Wu saw that Fan Wuxian was looking for him, of course, there could be no other reason, so he asked happily, he knew that Fan's Investment Group was rich, and if he could sponsor himself to engage in scientific research, or realize a batch of commercial solar energy utilization equipment, it would be quite constructive.

"Do you have any mature projects on your hands right now?" Fan Wuxian asked directly.

"Road lighting and solar heating are more feasible, but the key problem is the lack of materials." Professor Wu said very frankly.

In general, solar lighting is still very promising, a set of 400 watt conventional street lamps consume more than 1,000 kilowatts of electricity a year, which is equivalent to consuming more than 400 kilograms of standard coal. If you replace 1,000 sets of 150-watt solar street lamps with equivalent lighting effects, you can indirectly save millions of kilowatt-hours of electricity a year and save more than 400 tons of standard coal.

If a city or a thousand cities are replaced with this kind of solar street lamp, the energy saved, but it is a quite amazing amount, and by extension, if this range is further increased, gradually into the homes of residents, then the energy that can be saved, I am afraid that everyone will feel staggered.

Professor Wu also mentioned that the initial investment in a set of 150-watt solar street lamps is as high as 15,000 yuan, while the cost of each set of conventional street lamps is only about 8,000 yuan.

Although the service life of solar street lamps is long, and it can be the same as the investment in conventional street lamps after many years, the maintenance and replacement costs are higher in the later stage, such as the lead-acid battery commonly used in solar street lights, its service life is only four to six years, and the expensive battery must be replaced more than three times during the service life of solar street lights.

The photoelectric conversion efficiency of solar street lamp panels is low, which seriously affects the power generation efficiency of solar street lamps, and the cost of using solar power is currently about three yuan per kilowatt-hour, which is much higher than conventional power generation. At the same time, for urban roads with high illumination requirements for street lights, solar street lamps also have defects such as narrow light coverage and uneven brightness, which has become a great obstacle to the promotion and application of solar energy.

As a local government, even if a huge amount of money can be invested in a lump sum to use solar street lights for road lighting projects, but then more funds can not be taken out for later maintenance and replacement, and solar street lights have become decorations.

Due to the existence of these constraints, solar street lamps can only be promoted and applied in urban roads, parks, towns and other places with low brightness and illumination requirements at this stage, and cannot enter the main battlefield of lighting on a large scale.

"It's a really hard thing to solve." Fan Wuxian shook his head and said. There are no pop-ups
