Recently, the mainstream battery products in the photovoltaic industry are polycrystalline silicon batteries, but the cost is too high. Zhang Gong, a well-known expert in the field of solar cells and a professor at Tsinghua University, said at the “Environmental Energy Green Industry Forum”. In order to deal with the problem of high solar cell cost in the photovoltaic industry, we must find ways to improve the photoelectric conversion efficiency and reduce the cost of the composition. Thin-film solar cells can not use expensive silicon, mobile power manufacturers need less than polysilicon. Solar cells, energy consumption is also significantly lower than polycrystalline silicon solar cells, then thin film batteries become the inevitable way of solar cell development, but also represents the future direction.

A lifetime manufacturer of thin-film solar cells said that compared with polysilicon, thin-film solar cells have the advantages of low cost, mature technology and less pollution. The technical staff in the industry also said: "Wang Wensheng, thin film battery is a lithium battery un38.3 test to prepare a layer of film into a solar cell, because its silicon content is very small, it is easier to reduce costs."

Another expert in the year also stressed: "Compared with crystalline silicon cells, the potential cost of thin film batteries is much greater, mainly due to the technological advancement of thin film solar cells. Thin film solar cells may be expected to reach future capacity. 20% of the entire solar industry has a large space for expansion. Thin-film solar cells are facing technological breakthroughs at ordinary times. There are many physical methods for nickel-hydrogen battery production plants, such as the ion beam method for depositing nanocrystalline silicon thin films, assuming that domestic companies can Some improvement will be very promising."

"From the perspective of cost, the future thin-film solar cells have obvious advantages over crystalline silicon cells, and have obvious advantages over conventional energy sources such as thermal power." The film solar cells were also affirmed. The person also said that as the proportion of the photovoltaic industry in global energy is gradually improving, thin-film solar cells will rapidly expand under the demand of large-scale photovoltaic power plants and other applications.
