Example Embodiment
[0018] Embodiment 1: This embodiment is an annealing method for the anode of a perovskite solar cell, which is specifically carried out according to the following steps:
[0019] When the perovskite solar cell photoanode is heated and annealed on the heating table, the perovskite light absorber layer of the perovskite solar cell photoanode directly contacts the heating table, and the annealing temperature is 30℃~170℃. The treatment is carried out for 5 min to 30 min; the photoanode of the perovskite solar cell is sequentially composed of a conductive glass layer, an electron transport layer and a perovskite light absorbing agent layer from top to bottom.
Example Embodiment
[0020] Embodiment 2: The difference between this embodiment and Embodiment 1 is that the conductive glass is FTO conductive glass. Others are the same as the first embodiment.
Example Embodiment
[0021] Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the conductive glass is ITO conductive glass. Others are the same as in the first or second embodiment.
