Abstract

A perovskite battery, a laminated solar cell, a photovoltaic module, a photovoltaic power generation system and an electric device, belonging to the technical field of photovoltaics. The perovskite battery comprises a perovskite light absorption layer and an electron transport layer comprising at least two transport sub-layers. The material of the transport sub-layers comprises metal oxide M<x>O<y>, M representing a metal element. The ratio of the number of metal atoms to the number of oxygen atoms in the transport sub-layers is x/y, and in the direction from the perovskite light absorption layer to the electron transport layer, the value of x/y of the transport sub-layers successively increases. Regulating the ratio of the number of metal atoms to the number of oxygen atoms of the metal oxide in the multi transport sub-layers of the perovskite battery can successively decrease the energy level structure in the electron transport layer in the direction from the perovskite light absorption layer to the electron transport layer, improve the transport capability of carriers in the electron transport layer, and increase the current of the perovskite battery, allowing the perovskite battery to have relatively high photoelectric energy conversion efficiency.
