Abstract

The invention belongs to the field of semiconductor photoelectronic devices, specifically a semi-transparent perovskite solar cell. The solar cell comprises a transparent substrate, a first transparent electrode layer, a hole transmission layer, a perovskite light absorption layer, an electronic transmission layer and a second transparent electrode layer from the bottom to the top. The second transparent electrode layer serves as a battery cathode, and specifically is an electron extracting layer / conductive layer composite structure, wherein the conductive layer is a super-thin metal Ag or a conductive polymeric material PEDOT: PSS PH1000. The perovskite light absorption layer is of a semi-transparent structure, and other structures are transparent structures. The solar cell is low in cost, is high in efficiency, can be integrated in various types of products through the semi-transparent characteristic, and provides a new idea for the final industrialization of perovskite.

Description

technical field [0001] The invention belongs to the field of semiconductor optoelectronic devices, in particular to a high-efficiency, low-cost translucent perovskite solar cell. Background technique [0002] With the depletion of non-renewable resources such as coal, oil and natural gas, new energy, especially solar cells, has become a hot spot of research at home and abroad. At present, inorganic solar cells have been industrialized, but their cost is too high, and the efficiency of organic solar cells is too low, so the prospects are not clear. Since the first report in 2009, perovskite solar cells have been favored by researchers for their ultra-low-cost solution preparation process. The energy conversion efficiency has increased from the initial 3.8% to 20.2%. With the deepening of research, The efficiency of the cell is very likely to exceed that of the currently developed monocrystalline silicon solar cells. [0003] Currently, most solar cells are completely opaque...
