Abstract
The utility model relates to the field of solar cell, especially a new flexible perovskite solar cell with metal sheet as substrate, which comprises, from top to bottom, a front metal electrode grid line, a sandwich structure transparent conductive film layer, a buffer layer, an electron transport layer, a perovskite absorption layer, a hole transport layer I, a hole transport layer II, a conductive adhesive layer and a metal sheet substrate. The utility model uses a high-conductivity metal sheet as the substrate, which has the characteristics of flexibility, low resistance and high weather resistance. The light entrance surface has a sandwich structure transparent conductive film layer, which has good light transmission and power collection ability, and can prevent water vapor from penetrating into the cell, thereby maintaining the high stability of the cell.
