The utility model relates to the perovskite-based solar cell of a kind of organic inorganic hybridization, comprises substrate and stacks gradually transparency electrode on this substrate, electron transfer layer, ultra-thin oriented layer, perovskite light-absorption layer, hole transmission layer and to electrode.The utility model effectively can improve the inner carrier diffusion length of calcium titanium ore bed, prevents the compound at electron-hole pair and interface inner at calcium titanium ore bed, and then significantly improves photoelectric conversion efficiency and the stability of battery.Meanwhile, the directed template action of ultra-thin oriented layer, makes perovskite light-absorption layer crystalline quality not be vulnerable to membrance casting condition impact, improves repeatability prepared by device. |
