- 详细技术说明
- Professor Yang Yang and his research team have developed a unique perovskite solar cell that uses metal oxide films for the charge transport layer. Metal oxides offer the advantage of higher carrier mobility and superior stability than typical organic materials and they can be processed easily via solution. This unique lead halide perovskite solar cell has achieved a ~16% efficiency and improved stability of 60 days under normal operating conditions.

Background
Lead halide perovskite solar cells offer excellent photovoltaic efficiencies (up to 15%), but both the perovskite material and the charge transport layers have poor stability, where the device degrades within days under normal conditions. Specifically, organic charge transport layers are important for energy level matching and charge transport, but their use is limited because they have poor device stability and are costly to fabricate. The use of inorganic materials to replace the organic transport layers offers a promising avenue to circumvent the disadvantages of these layers for solar cell applications.
