Polaris solar photovoltaic (pv) and 27. 0%! Four-terminal perovskite - Silicon laminated solar cells developed

The low band gap battery widened sunlight photon utilization; Specifically, CGNPC in development of 410 mw, 603 mw, guangzhou energy saving 220 mw, 345 mw, jin can group the people vote for 200 mw, 190 mw hubei energy group, huaneng 180 mw perovskite battery is the third generation of solar cell, which is developing rapidly in recent years, it has abundant raw materials, low cost, simple preparation technology, the advantages of good tolerance for defects. Crystalline silicon solar cell is the first generation of solar cells, after decades of development, the technology is already very mature. Solar building the translucent perovskite solar cells and the photoelectric conversion efficiency of 23. 3% of silicon heterojunction thin-film batteries, the photoelectric conversion efficiency of 27. 0% of the four-terminal laminated solar cells. Solar photovoltaic (pv) net news: recently, dalian institute of chemical physics, Chinese Academy of Sciences thin film silicon solar cell research group ( DNL1606) Yang Dong Liu Shengzhong researcher joint team of shaanxi normal university researcher, through the translucent perovskite combination with efficient silicon heterojunction thin film battery, in power stations of the photoelectric conversion efficiency reached 27. 0% of the four-terminal perovskite - Silicon laminated solar cells. （ Wen/figure Duan Lianjie, Wang Ziyu) Solar photovoltaic (pv) network statement: this information is reproduced from the media or other Internet web site, network cooperation photovoltaic network published the article for the purpose of the information, does not mean that agree with his point of view or confirm its description. Through the ion replacement, perovskite band gaps can be in 1. 4 to 2. 3 eV between flexible adjustment, make it become the ideal material of laminated electric battery pool. Laminated battery by a high band gap batteries and a low band gap of child battery. Under the laws of physics, the efficiency of crystalline silicon path of ascension is becoming more and more narrow. This study used a simple low cost method of preparation of high conductivity, high transparent transparent electrode, facilitate translucent and multi-junction/laminated battery development, reduce the cost of photovoltaic power generation. Perovskite structure general formula is ABX3, A bit is usually are monovalent organic cationic CH3NH3 +, NH = CHNH3 Cs + + or inorganic ions, drum regenerative B who usually are divalent metal cations Pb2 +, Sn2 +, etc. At present, the steam drum regenerative lab reports of perovskite battery photoelectric conversion efficiency over 24%. Relevant results are published in the advanced functional materials, 先进功能材料) On. Lab reports the best crystal silicon solar battery photoelectric conversion efficiency has been achieved. 6%, solar equipment, very close to its theory of the photoelectric conversion efficiency limit of 29. 4%. Therefore laminated battery is higher than single junction battery limit photoelectric conversion efficiency. Get high efficiency solar cell is one of the key of preparation of transparent electrode under mild conditions, namely without harm to the underlying material, the preparation of electrodes with high conductivity and high light penetration. The article content is for reference only. At present, 95% of the photovoltaic market share is crystalline silicon solar cells. X is usually halogen anion I - Br - Cl - And so on. Photovoltaic brackets

with 18 were translucent perovskite solar cells. The photoelectric conversion efficiency of 3%, China solar power network, this is the use of ultra-thin metal and translucent perovskite is one of the highest efficiency of the battery. The team used the method of vacuum thermal evaporation deposition film, China solar energy network, installation of photovoltaic contracting price list by molybdenum oxide/gold nanoparticle network/molybdenum oxide & other; Sandwich structure & throughout; As a transparent electrode, the dachaoshan hydropower station to replace the traditional perovskite metal back electrode in the battery. Among them, the EPC project owner units is given priority to with soe/state, this also reflected from the side, the solar energy portal, in project bidding and parity, the state-owned enterprises have become the absolute main force. Solar building the work obtained the national natural science foundation of China, the Chinese national key research and development plans, such as shaanxi science and technology innovation to guide project funding. Photovoltaic contracting installation price list this paper statistics the September to today issued a total of 2. 85 gw pv power plant EPC and 1. 9 gw component bid opening information. In order to achieve higher photoelectric conversion efficiency of solar power network, more and more studies begin to pay close attention to of crystal silicon and other high efficient battery laminated batteries. High band gap child battery reduces the semiconductor electron transition after capturing high-energy photons relaxation process of thermal energy loss.
