Functionalized polyethyleneimines that are compatible with non-fullerene acceptors have been developed by protecting the reactive amine groups, leading to non-fullerene solar cells with high power conversion efficiency and enhanced thermal stability.
Achieving high power conversion efficiency (PCE) polymer solar cells (PSCs) has been very challenging and the ultimate goal for their commercialization. Precise investigation of the active layer morphology and newer...
Tandem configuration-containing perovskite and silicon solar cells are promising candidates for realizing a high power conversion efficiency of 30% at reasonable costs.
Incorporation of appropriate amounts of Cs and Cl into the perovskite precursor could improve the stability of corresponding devices. A high power conversion efficiency of 20.31% without hysteresis is realized.
