Inventor: Qi Jianping, Suzhou Sibolu Photovoltaic Energy Technology Co., Ltd.
Project Name: Flexible Solar Cell
Background of the invention:
The conventional crystalline silicon battery has disadvantages such as large pollution, high energy consumption, and heavy battery components (including brackets). In order to reduce costs and realize the large-scale utilization of clean energy, the world is reducing the weight and cost of the battery. Every effort has been invested in the area, and the thin film battery industry has emerged. Thin film batteries can greatly save expensive semiconductor materials, reduce battery preparation processes, and use low temperature processes to reduce energy consumption. Thin film batteries have made great strides in R&D and application.
At the same time, since the thin film battery can be deposited on a flexible metal or plastic substrate, its weight is greatly reduced, it can be bent and folded, the assembly is easy to carry and transport, and the power to weight ratio is high, so the preparation and production of the flexible battery become The crown jewel in the photovoltaic field.
Due to the special nature and application of flexible batteries, western countries have imposed various restrictions on China's production equipment for large-scale flexible batteries, and the manufacturing process of flexible batteries is the core secret of enterprises. R&D and production companies are concentrated in the United States, making the products China's R&D and production have been stagnating for years.
Application Market:
Outdoor (field) solar power, emergency energy; Operational and living energy for oil exploration, mining exploration, etc.; BIPV is used for roof and wall power generation; special areas such as stratospheric airships, individual equipment, etc. .
Prospects estimate:
Flexible substrate solar cells can be placed on top of streamlined automobiles, uneven surfaces such as sailing ships, rowing boats, and motorboats, roofs and exterior walls of buildings and other buildings. In addition, because the flexible thin-film battery has a high mass specific power (500w/kg) and is flexible at the same time, it is very suitable for the observation of stratospheric airship surface, and the military has a bright future.
The development of BIPV is currently a major research hotspot for photovoltaic power generation in the world. Western developed countries are actively conducting key projects. In addition to installing photovoltaic panels on the roof, products have been introduced to install photovoltaic cells in tiles. In addition, PV WALLs are also being researched abroad, combining PV systems with building facades. It can be expected that the combination of photovoltaics and buildings is one of the most important fields in the future of photovoltaic applications. Its development prospects are very broad and there is a huge market potential. Flexible substrate thin-film batteries will undoubtedly play an important role in them.
