From this perspective, GCL Nano's perovskite solar modules are definitely groundbreaking products, and it is expected to rewrite the monolithic situation of crystal silicon in the future, bringing new opportunities and vitality to photovoltaic power generation.


With the emergence of a large number of unsubsidized projects in 2019, China's photovoltaic power generation will officially usher in the era of cheap Internet access. At the same time, photovoltaic power generation, which has been previously protected by state subsidies, will also directly participate in the power market competition. Therefore, high efficiency and low cost will become the lifeline of photovoltaic power generation in China.


It is precisely because of this that in recent years, PEC, IBC, N-type and other battery technologies and processes have developed rapidly, and high-efficiency solar modules such as double-sided, stacked tiles and half-chips have also begun to rapidly occupy the market. However, compared with the crystalline silicon solar modules with the above technologies and processes, there is a new type of solar module with more subversive innovation power, and it has been successfully tested in the near future, which is expected to cause a new round of industrial transformation.


Successful trial production of new solar modules

Recently, Suzhou GCL Nanotechnology Co., Ltd. (referred to as GCL Nano), a subsidiary of GCL Group, announced that they have taken the lead in building a 10MW-scale large-area perovskite solar module pilot production line, completing the development of related materials synthesis and manufacturing processes, and The construction of a 100MW production line has begun, and commercial production of perovskite PV modules is planned to be achieved by 2020.

It is understood that the size of the perovskite PV module manufactured by GCL Nano's 10MW pilot production line is 45cm*65cm, and the photoelectric conversion efficiency reaches 15.3%. This is the largest area of ​​perovskite photovoltaic modules worldwide and the highest value for large-area perovskite solar modules.


As a third-generation solar cell technology, perovskite solar cells have long been regarded as a new direction to replace crystalline silicon cells in the future. At present, the laboratory efficiency of perovskite battery has reached more than 23%, surpassing the highest efficiency of polysilicon solar cell laboratory. What is embarrassing is that with the great research of the world's major laboratories, the laboratory efficiency of perovskite battery is still high. In a fast-paced high.

Compared with crystalline silicon solar modules, perovskite modules are low in cost and have superior semiconductor performance. The material conversion performance of about 90% can achieve more than 20% photoelectric conversion efficiency, while the purity of solar grade silicon must reach 6N. In addition, perovskites have a stronger absorption capacity and a higher theoretical efficiency limit.

Although there are many advantages over crystalline silicon cells, perovskite solar modules have fatal drawbacks, which is the main reason why this type of solar module is still not used on a large scale. First, the area of ​​perovskite solar modules is difficult to enlarge. Currently, the area of ​​perovskite cells developed by the laboratory is very small, and it is difficult to mass-produce. Secondly, the perovskite solar modules are relatively unstable and their core The layer is susceptible to external influences such as temperature and humidity, and the efficiency is greatly degraded.

Why is the perovskite solar module of GCL Nano's trial production extremely disruptive? Because they overcome the above two major defects of the perovskite solar module. First, the size of the perovskite PV module manufactured by GCL Nano's 10MW pilot line reached 45cm*65cm, which has the potential to be applied in large-scale power plant projects. Secondly, the working life of the module is expected to reach more than 25 years.

From this perspective, GCL Nano's perovskite PV modules are absolutely groundbreaking products, and it is expected to rewrite the monolithic situation of crystal silicon in the future, bringing new opportunities and vitality to photovoltaic power generation.


Or will cause change

Some people may be confused. Although the area of ​​the perovskite solar module of GCL Nano has a big breakthrough, it is still smaller than the area of ​​the crystalline silicon solar module, and its photoelectric conversion efficiency is only 15.3%. There is still a big gap compared to crystalline silicon solar modules, so why is it that this solar module will cause change?

Don't forget, the reason why solar cells pursue high efficiency is ultimately to reduce costs. Whether it is from the acquisition of raw materials or the preparation process, the cost of perovskite batteries is so low that it is difficult for crystalline silicon to look back!

According to reports, under the existing process conditions, the manufacturing cost of perovskite PV modules manufactured by GCL Nano 100MW production line is expected to be less than 1 yuan / W, when the capacity is expanded to more than 1GW, the perovskite solar modules Manufacturing costs will further drop to around 0.7 yuan per watt.

What is this concept? This means that the price of perovskite PV modules can easily be less than 1.5 yuan / W, and after the "531" baptism, the current crystalline silicon solar modules are still between 1.78 yuan / W -2.3 yuan / W. This means that the price of photovoltaic systems using perovskite PV modules can easily be less than RMB 3/W, and even with state subsidies, the price of PV systems using crystalline silicon solar modules is hard to be lower than RMB 4/W.

Moreover, the area of ​​the perovskite photovoltaic module will never be 45cm*65cm, and its efficiency will never stop at 15.3%. It is understood that GCL Nano is building a 100MW production line, which will expand the module area to 1m*2m, and the photoelectric conversion efficiency of the module will increase to over 18%.

The huge cost advantage will give the most competitive competitiveness of perovskite PV modules. In addition, perovskite PV modules are also flexible, light and thin. Once the relevant enterprises can overcome various difficulties and achieve mass production of perovskite PV modules, the cost of photovoltaic power generation will not only be lower than that of thermal power, but also rapidly expand. Application area. That is why the perovskite PV modules will bring about change.

Fortunately, China's PV companies have reached the forefront of the international market in the field of perovskites, not only the pioneer companies that have already prepared to produce production lines, but also the efficiency of the world's perovskite PV modules. Record of the business. I believe that in the near future, perovskite PV modules will shine!
