| abstract |
The invention discloses an environment-friendly perovskite photovoltaic material and a preparation method thereof. The present invention replaces the cation Pb in the traditional perovskite structure photovoltaic material CH 3 NH 3 PbX 3 (where X represents one or more halogens) with environmentally friendly magnesium, barium, and zinc, and the anion uses sulfate , nitrate, phosphate, etc., to prepare environmentally friendly photovoltaic materials with a perovskite structure. |
