The invention relates to a low-cost perovskite solar cell and a preparation method thereof. This type of solar cell consists of an FTO transparent conductive glass substrate, a TiO2 dense layer, a TiO2 mesoporous layer, a porous ZrO2 barrier layer, a NiO mesoporous layer and The light-absorbing material is CH 3 NH 3 PbI 3 with a perovskite structure. The light-absorbing material is evenly distributed between the TiO 2 mesoporous layer and the conductive carbon electrode by the infiltration method. The preparation method is simple, and the battery has good performance. The photoelectric conversion efficiency is high, and the battery performance can be stored for a long time at room temperature with little degradation. |
