Description

technical field [0001] The invention relates to a solar battery device and a preparation method thereof. Background technique [0002] Solar cell devices have been widely used due to their advantages of cheapness, cleanliness, and renewability. The currently commonly used solar cell device structure includes an anode, a hole buffer layer, a first active layer, an electron buffer layer and a cathode stacked in sequence. After the excitons in the first active layer are separated to generate holes and electrons, the holes reach the anode, and the electrons reach the cathode, where they are collected by the electrodes to form effective energy conversion. Currently, conventional solar cells have low energy conversion efficiencies. Contents of the invention [0003] Based on this, it is necessary to provide a solar cell device with high energy conversion efficiency and a preparation method thereof. [0004] A solar cell device, comprising an anode, a hole buffer layer, a firs...
