Nanodiamond-based hybrid perovskite solar cell and preparation method thereof

The invention discloses a nano-diamond-based hybrid perovskite solar cell and a preparation method thereof, and the method comprises the steps: obtaining and cleaning a conductive substrate which comprises a glass substrate and a transparent oxide bottom electrode; growing an improved electron transport layer containing nano diamond particles on the transparent oxide bottom electrode; growing a hybrid perovskite light absorption layer on the improved electron transport layer; growing an improved hole transport layer containing nano diamond particles on the hybrid perovskite light absorption layer; and growing an interface top electrode on the improved hole transport layer. On the basis of the perovskite solar cell, the nano-diamond material is adopted to dissipate heat, so that the heat conductivity of each layer of the device can be improved, and the heat stability of the whole device is improved while the whole photovoltaic structure and performance of the original device are not damaged. 本发明公开了一种基于纳米金刚石的杂化
