AI Technical Summary
Technical Problem
In existing perovskite solar cells, the hole transport material Spiro-OMeTAD is expensive and has poor long-term stability, which limits the improvement of device performance. There is a need to develop a self-assembled monolayer material that is simple in structure, low in cost, and has excellent performance.
Method used
Carbazole derivatives with rigid conjugated large planes are used as self-assembled monolayer hole transport materials. Perovskite interface defects are passivated by terminal phosphate anchoring groups, optimizing molecular ordered stacking and improving hole mobility.
Benefits of technology
It significantly improves the photoelectric conversion efficiency and lifespan of perovskite solar cells, reduces interface energy loss, and achieves longer stability.
