Abstract
A solar cell module includes a first substrate and a plurality of photoelectric conversion elements disposed on the first substrate. Each of the plurality of photoelectric conversion elements includes a first electrode, an electron transport layer, a perovskite layer, a hole transport layer, and a second electrode. In at least two of the photoelectric conversion elements adjacent to each other, the hole transport layers are extended continuous layers; and the first electrodes, the electron transport layers, and the perovskite layers in the at least two of the photoelectric conversion elements adjacent to each other are separated by the hole transport layer. The hole transport layer includes, as hole transport material, a polymer having a weight average molecular weight of 2,000 or more or a compound having a molecular weight of 2,000 or more.
