Abstract: A method for preparing a perovskite cell with multiple hole transport layers is described. The method includes a process of forming the multiple hole transport layers, where the process of forming the multiple hole transport layers includes the following steps: (1) sputtering a nickel oxide target material in a first atmosphere to form a first hole transport layer, where the first atmosphere contains argon and oxygen, and a volume ratio of the argon to the oxygen is approximately 0:1 to 1.5: 1; (2) performing annealing treatment on the first hole transport layer; and (3) sputtering the nickel oxide target material onto the first hole transport layer subjected to the annealing treatment in a second atmosphere to form a second hole transport layer, where the second atmosphere contains argon-containing gas and oxygen. A perovskite cell (100) with multiple hole transport layers prepared by using the above method is described.

Abstract: A solar cell includes a plurality of sub-cells. The plurality of sub-cells are disposed sequentially along a first direction. The plurality of sub-cells each include a first photovoltaic conversion layer for performing photovoltaic conversion. The first direction is perpendicular to a thickness direction of the sub-cells. Along the first direction, a trend of change in a thickness of the first photovoltaic conversion layer of each sub-cell is negatively correlated to a trend of change in a cross-sectional area, perpendicular to the thickness direction, of each first photovoltaic conversion layer, so as to improve uniformity of photocurrents output by the sub-cells and uniformity of electrical current.
