| titleOfInvention | A kind of quantum dot solar cell and preparation method thereof |
| abstract | The invention provides a quantum dot solar cell, comprising a conductive substrate, an interface buffer layer, an n-type PbS quantum dot layer, a p-type PbS quantum dot layer and an electrode layer which are stacked in sequence; the interface buffer layer is made of Al At least one of 2 O 3 , ZnO and SnO 2 . The invention uses at least one of metal oxides Al 2 O 3 , ZnO and SnO 2 as the material of the interface buffer layer, which can effectively passivate the interface defect between the conductive substrate and the n-type PbS quantum dot layer and adjust the energy band structure. , effectively improving the photoelectric performance of quantum dot solar cells; at the same time, the light absorption layer and the hole transport layer, namely the n-type PbS quantum dot layer and the p-type PbS quantum dot layer are arranged adjacent to each other to form a p-n junction, thereby further improving the interface. At the same time, it can effectively suppress the generation of hysteresis phenomenon. |
