Abstract: Polymer transport materials for application in perovskite solar cells capable of being tuned or manipulated to achieve desired properties, are provided herein. The present disclosure is directed to methods, systems, and compositions for achieving polymer transport materials (i.e., hole transport materials (HTMs)) with desirable properties such as solution processability, energy level tuning (i.e., adjusting), high thermal properties, tunable (i.e., adjustable) wettability, and perovskite defect passivation. In some aspects of the present disclosure, the synthesis of such HTMs may be implemented via relatively simple and inexpensive processes.

Abstract: Methods and systems for reducing solar cell degradation are provided. The methods and systems related to frequently applying large reverse bias current-voltage (J-V) sweeps to the cell to reduce the rates of internal degradation of the solar cells. The frequent sweeps serve to detrap charge carriers formed in the cell due to photo-oxidative damage. This detrapping reduces the rate of power conversion efficiency (PCE) degradation throughout the life of the solar cell.
