Description

technical field

[0001] The invention relates to the technical field of solar cells, in particular to a carbon electrode for carbon-based perovskite solar cells and a preparation method thereof. Background technique

[0002] Perovskite solar cells have been widely studied, and have the advantages of high photoelectric conversion efficiency, low cost, and simple preparation process. Since 2009, its efficiency has been soaring, and the highest certified efficiency has reached 23.3%. Almost all high-efficiency perovskite solar cells prepare counter electrodes by evaporating precious metals such as gold and silver. These noble metal electrodes and the required high-vacuum evaporation equipment greatly increase the cost and energy consumption of the battery. In addition, the reaction of silver with halide ions and the penetration of gold into the active layer will cause the degradation of device performance, which will adversely affect the stability of the battery and the commer...
