Photovoltaic market thin film battery will have more advantages than polysilicon

Recently, the mainstream battery products in the photovoltaic industry are polysilicon 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 high cost of solar cells in the photovoltaic industry, it is necessary to think of ways to improve the photoelectric conversion efficiency and reduce the cost of the system. Thin-film solar cells may not use expensive silicon, and mobile power supply manufacturers need less materials than polysilicon. Solar cells, energy consumption is also significantly lower than polycrystalline silicon solar cells, thin-film batteries become the inevitable way for the development of solar cells, but also represents the future direction of development.

A thin film solar cell life-long production company said that compared with polysilicon, thin-film solar cells have the advantages of low cost, mature technology, and less pollution. Industry technicians also said: "Wan Wensheng, thin-film battery is a lithium battery un38.3 test will be a film made of solar cells, because of its small amount of silicon, it is easier to reduce costs."

Another expert also stressed that: "Compared with crystalline silicon cells, the potential for cost reduction of thin-film batteries is much greater, which is mainly due to the technological advancement of thin-film solar cells. The thin-film solar cells may be expected to reach future capacity. 20% of the entire solar industry has more room for development, and thin-film solar cells are facing technical breakthroughs, and there are many physical methods for nickel-metal hydride battery manufacturing plants, such as the ion beam method for depositing nanocrystalline silicon thin-film technology, assuming that domestic companies can There will be great prospects for improvement."

"From the perspective of cost analysis, the future of thin-film solar cells has obvious advantages over crystalline silicon cells, and has obvious alternative advantages over conventional energy sources such as thermal power." It also affirmed the development of thin-film solar cells. The person in charge also stated that as the proportion of the photovoltaic industry in the global energy industry has gradually improved, thin-film solar cells will rapidly expand under the application requirements of large-scale photovoltaic power stations.
