Description

technical field [0001] The invention belongs to the field of solar cells, in particular to a method for controlling CH based on water doping 3 NH 3 PB 3-x Cl x Preparation of crystalline high-efficiency perovskite solar cells. Background technique [0002] Organic-inorganic halide perovskite is a low-cost, easy-to-prepare new light-absorbing layer material for solar cells. This organometallic halide with a perovskite structure has a long carrier life, good light absorption And bipolar transmission characteristics, in just a few years, its photoelectric conversion efficiency has increased from the initial 3.8% to the current 20.1%. [0003] At present, the relatively simple and efficient preparation method is based on CH 3 NH 3 PB 3 (or CH 3 NH 3 PB 3-x Cl x ) system as the representative planar structure battery, among which the simpler one-step solution method is often used as the preferred method for preparing the system. However for CH 3 NH 3 PB 3 (MAPbI ...
