The invention relates to a hole transport layer solution with a photoactive layer passivation effect and a preparation method and application thereof, and the preparation method comprises the step of mixing a dopant with a hole transport layer base solution to obtain the high-performance hole transport layer solution with the photoactive layer passivation effect. Compared with the prior art, p-type doping of the hole transport layer can be realized in an oxygen-free environment. More importantly, a reaction product generated in the doping process can be used as a passivator and spontaneously enters the perovskite layer from the hole transport layer to passivate perovskite body defects and upper and lower interface defects. According to the method, the photoelectric conversion efficiency of the perovskite solar cell is further improved, and the stability and repeatability of the device are improved. 本发明涉及一种具有光活性层钝化作用的空穴传输层溶液及其制备方法与应用，制备方法包括：将掺杂剂与空穴传输层基液混合，即得到高性能且具有光活性层钝化作用的空穴传输层溶液。与现有技术相比，本发明可在无氧环境下实现空穴传输层的p型掺
