On the 21st at the 5th China Battery Technology Innovation (Shanghai) Forum, Yu Junhao, academician of the Chinese Academy of Sciences and director of the Shanghai Solar Cell R&D Center, introduced the development of thin-film solar cells at home and abroad. He said that thin-film solar cells are flexible, light-weight, beautiful, etc. The characteristics will increase in the fields of building roofs, translucent facades, and shading systems. EU betting breakthrough In recent years, the European Union has continuously invested in the field of thin film solar cells. At present, some key technologies for thin film solar cells have achieved breakthroughs. In 2012, the European Union announced that it will provide a budget of 10 million euros for the "nano-scale" thin-film solar cell project by 2015. There will be 13 European research teams participating in the development of chalcogenide solar cell technology. The task of the project is to significantly reduce the production cost and improve the conversion efficiency of the thin film module through nanostructured materials. Some analysts pointed out that the photovoltaic dispute between the EU and China is actually aimed at suppressing the crystalline silicon cells and supporting thin-film batteries. At present, the global solar photovoltaic industry mainly uses crystalline silicon solar cells and thin-film solar cells as the two main lines. The vast majority of companies in China are concentrated in the crystalline silicon sector. The EU's intention is obvious. According to reports, U.S. scientists use low-cost copper-zinc-tin-sulfur materials in combination with ethylene glycol to produce copper-zinc-tin-thin-film thin-film solar cells that are inexpensive and do not contain toxic compounds. At present, many thin-film solar cells are made of copper indium gallium selenide. The raw materials are expensive, and copper-zinc tin-sulfur thin-film solar cells solve the price problem. In addition to price, battery efficiency becomes a key technology. Junjun Hao introduced that the efficiency of thin-film batteries developed by the Shanghai R&D Center for Solar Cells has reached 20.4%, while the efficiency of 15% can be applied in large areas. Wide application prospects According to Junjun Hao, the first-generation photovoltaic cells are crystalline silicon solar cells including single crystal silicon and polysilicon, and the second generation of photovoltaic cells include amorphous silicon, gallium arsenide, cadmium telluride, copper indium gallium selenide, etc. The third generation includes fuel. Sensitization, wide spectrum, stacked multi-junction, quantum dots/nano, organic batteries and many other new concept batteries. Thin-film batteries mainly refer to the second-generation and third-generation batteries. Some of the third-generation batteries are still in the laboratory stage, and they have not entered the market. Recently, the demand for photovoltaics has slowed down, but thin-film solar cells are better than crystalline silicon cells due to their characteristics of flexibility, light weight, and aesthetics. Junjun Hao pointed out that in some areas that do not apply crystalline silicon cells, thin-film batteries have played a role, such as in the building roof, translucent facades, shading systems and other fields. Due to its flexible nature, thin-film solar cells can even be used on clothes and tents. The high-efficiency features make thin-film solar cells applicable to aircraft, airships, and solar-cell vehicles. Junjun Hao, for example, said that lithium batteries and solar cells can be used on electric vehicles at the same time. When sunlight is sufficient, they can use solar energy and use endless amounts of solar energy to store in lithium batteries, which can also reduce the conventional charging of lithium batteries.
