Embodiment 1
[0015] The structure of the perovskite solar cell is: a transparent conductive electrode and an electron transport layer stacked on the electrode in sequence, a perovskite structure light absorption layer, a black phosphorus nanoparticle hole transport layer and a positive electrode. Among them, the transparent conductive electrode is indium tin oxide, the electron transport layer is ZnO, the light-absorbing layer of perovskite structure is CH3NH3PbI3 layer, and the positive electrode is gold electrode layer or silver electrode layer.
Embodiment 2
[0017] The manufacturing method of the perovskite solar cell structure is as follows: step 1, sequentially form an electron transport layer and a perovskite structure light-absorbing layer on the transparent conductive electrode by conventional deposition, sputtering or spin coating; step 2, in the case of isolating the air Next, get black phosphorus and grind, and the black phosphorus after grinding is dispersed in organic solvent (organic solvent comprises N-methylpyrrolidone (NMP), dimethylformamide (DMF), dimethyl sulfoxide (DMSO) , acetone, tetrahydrofuran, absolute ethanol, methanol, isopropanol, chloroform and dichloromethane) to obtain a dispersion with a concentration of 0.6 to 1.2 mg / mL; the dispersion was first Perform probe-type ultrasonication at a power of 1000-1400W for 2-4 hours, and then perform water-bath ultrasonication at a power of 200-400W for 8-12 hours; after the ultrasonication is completed, centrifuge and collect the supernatant; step 3, the collected ...
