At the same time, uniform core-shell type ZnO @ SnO2 nanoparticles are favorable to the inorganic perovskite thin film growth. The solar cell is a kind of transform solar energy into electricity, realize the importance of energy conservation and emissions reduction products. For perovskite solar cells, the electron transport material is an important factor to determine its photoelectric conversion efficiency. High temperature heat storage ZnO @ SnO2 nuclear & ndash; The size of the shell nanoparticles to 8. 1 nm, electron mobility is 7 times of SnO2 nanoparticles. Hing for with professor at the university of California, Los Angeles, suzhou university professor Wang Zhaokui cooperation, solar portal, in view of the perovskite electronic transmission of solar cell material were studied, through solvent hot method to design a new type of electronic transfer materials tin oxide coated zinc oxide core-shell nanostructures ( ZnO@SnO2) 。 High temperature heat storage, then, China solar energy network, perovskite solar cells can further improve the photoelectric conversion efficiency, make solar energy & other; Throughout the &; ? The results of the study are put forward for the first time tin oxide coating preparation methods of nanometer zinc oxide core-shell structure, reveals the high photoelectric conversion efficiency of internal mechanism. Solar energy engineering machine construction project management software these results indicate that the photovoltaic applications where tin oxide coated zinc oxide core-shell nanostructures is an ideal electronic transport layer, solar cells solar power network, the photoelectric conversion efficiency than the traditional electron transport materials increased by 40%. Construction project management software, the results of the study to the tin oxide coated zinc oxide core-shell structure nanoparticles effectively improve inorganic perovskite solar photoelectric conversion efficiency ', solar portal, published in the international famous academic journal 'journal of the American chemical society. Recently, China university of petroleum ( Beijing) New energy and materials institute associate researcher hing waiting for perovskite electronic transmission of solar cell material were studied, photovoltaic applications where materials, design a new type of electronic transmission photoelectric conversion efficiency than the traditional electron transport materials increased by 40%. Applied to the field of solar power for the first time since 2009, perovskite based on superior performance, low cost and other characteristics, is thought to have a huge commercial value, perovskite solar cells are increasingly attention and welcome. Because the SnO2 shell energy level matching and nuclear layer of ZnO nanoparticles of high electron mobility, solar energy, inorganic perovskite solar photoelectric conversion efficiency is as high as 14. 35%.
