The photovoltaic power station invested by Huaxing Technology Group Company in Qiongzhou Province is in the dry and rainy area in the south of Qiongzhou Province, and it is also the place with the longest sunshine time, with an average daily sunshine hour of up to 9.5 hours, so the peak time of power generation of this photovoltaic power station is still very long.

After inspecting the energy storage system, Yang Jie also specially inspected the large-scale photovoltaic panel array site here.

The large-scale photovoltaic arrays here are mainly based on the second-generation photovoltaic panel modules developed by Huaxing Photovoltaic Technology Co., Ltd., but there are also some third-generation silicon-based thin-film cells, and even the fourth-generation gallium nitride solar cells completely independently developed by Huaxing Photovoltaic Technology Co., Ltd.

Huaxing Technology Group Co., Ltd. regards the large-scale solar power station here as a test and verification base for solar cell technology, and once there is a new type of product, it will be sent here for testing and verification.

The core technical team of Huaxing Photovoltaic Technology Co., Ltd. took the technical route of gallium nitride solar cells at the beginning, and has not stopped until now.

However, it also acquired several overseas crystalline silicon solar cell companies through technology acquisition, obtained a complete monocrystalline silicon solar cell technology system, and opened up the whole industry chain, from the production line equipment of upstream photovoltaic cells and modules, to the production of midstream cells and modules, and then to the power generation of downstream power stations.

Of course, Yang Jie also listened to the suggestions of several scientists, and recruited a technical team to develop a nanocrystalline silicon technology process based on the monocrystalline silicon solar cell technology mastered in his hands, which can prepare 200 microns of single crystals on the glass substrate, eliminating the need to prepare crystal rods and then cutting and polishing steps, which suddenly reduces the amount of silicon to one percent of the previous one, greatly reducing the cost of materials.

In the past, monocrystalline silicon was expensive mainly because monocrystalline silicon was an expensive material, which could account for 40% of the cost of monocrystalline silicon solar cells, and Huaxing Photovoltaic Technology Co., Ltd. also introduced the thin-film transistor preparation process and a new type of solar cell structure to prepare the third generation of monocrystalline silicon solar cell modules of Huaxing Photovoltaic Technology Co., Ltd.

The previous monocrystalline silicon solar cells were mainly prepared by high-temperature diffusion furnace and screen printing, and the process has been finalized, but Huaxing Photovoltaic Technology Co., Ltd. has completely transformed these processes by relying on the strong strength of Huaxing Technology Group Company in the semiconductor process.

This third-generation monocrystalline silicon solar cell is manufactured using the integrated circuit method, and multiple tandem cells are made at one time on a flat plane with an appropriate mask process, achieving mass production.

After the new process was determined, Huaxing Photovoltaic Technology Co., Ltd. sold all the outdated equipment and processes to other companies, and at the same time built the third-generation solar cell production line in China.

The spectral response of the third-generation solar cell panel launched by Huaxing Photovoltaic Technology Co., Ltd. extends from visible light to the infrared region, which has a wider spectrum energy absorption effect than the previous solar cells, so that the battery can generate electricity in a weak light environment or scattered light, cloud, and rainy environment, and the power generation can be about 20% more than the previous crystalline silicon cell in the case of the same power installed capacity.

At present, the main business of Huaxing Photovoltaic Technology Co., Ltd. is to undertake the construction bidding projects of various photovoltaic power stations all over the world, provide complete technical solutions, and do not compete with these photovoltaic manufacturers.

Now that China is vigorously developing photovoltaic power stations, Huaxing Photovoltaic Technology Co., Ltd. only provides the most core solar panel components, inverters and other core components, and does not compete with these manufacturers.

Now the state is calling for the vigorous development of new energy, especially in the northwest region has launched large-scale photovoltaic and wind power stations, which is in full swing.

However, Yang Jie is not very interested in this, because these projects are going to state subsidies, and many enterprises themselves have no technical background in the field of photovoltaic power generation and wind power generation, mainly purchasing various products and equipment from home and abroad to build these projects, and there is no technical ability to solve the technical defects of these two new energy sources.

It is foreseeable that it will be difficult to integrate these projects into the grid for power supply after completion, and the local economy is small, the power absorption capacity is limited, and these projects do not have an energy storage system to carry out peak shaving, the national grid will not let these projects be integrated into the grid to the eastern provinces and regions.

After a few years, these projects will definitely lose their bottoms, so Yang Jie doesn't want to get involved at all.

Of course, these products and equipment that photovoltaic technology companies should sell still have to be sold, and they will not do anything evil to pour cold water on these projects.

After all, the starting point of the state's support for these wind power projects is very good, but the technical strength of these domestic enterprises is not enough, and it is very difficult to get these subsidies.

If there is a large-scale curtailment of wind and solar power in the future, these projects will not be able to run anyway, which is a great business opportunity for Huaxing Technology Group to promote energy storage systems.

Yang Jie looked at these photovoltaic arrays in front of him, but his thoughts drifted to the side.

"Yang Dong, this is the fourth-generation gallium nitride solar panel we developed. ”

At this time, Dr. Dai Chuming, who was in charge of the gallium nitride solar cell technology department, said to Yang Jie with a proud face.

Yang Jie's thoughts were pulled back at this time, and he then carefully looked at the gallium nitride solar panel array in front of him.

The deep black underneath the fourth-generation GaN solar panel in front of you is very different from the deep blue of the third-generation silicon-based solar panel next to it.

Huaxing Photovoltaic Technology Co., Ltd. has insisted on the research and development of gallium nitride solar cell technology for so many years, and now it has finally realized the commercialization in the civilian field.

This is mainly due to the fact that Huaxing GaN Material Technology R&D Center has prepared a variety of materials suitable for the preparation of gallium nitride optoelectronic devices, including gallium nitride indium.

Huaxing GaN Material Technology Research Center can now prepare high-quality, high-indium GaN indium materials, and has also developed several transparent conductive films, including tin-doped indium oxide, aluminum-doped zinc oxide films, etc., and the R&D center has also mastered the processing technology of these thin film electrode materials, which have been used as contact electrodes for gallium nitride in various optoelectronic devices in recent years.

On this basis, Huaxing Photovoltaic Technology Co., Ltd. has also designed a chip structure design with very high photoelectric conversion efficiency.

The technical team analyzed the influence of each layer of the chip on the photoelectric characteristics of the solar cell by changing the thickness of each layer of the chip, the indium content, the doping concentration and the depth and width of the quantum well.

When Yang Jie saw the product in front of him, he was also quite emotional: it is really not easy to develop high-performance GaN solar cell chip products!
