Fig. 17. Symbolic depiction of the development of PSCs, (a) using classic PCBM preparation route, (b) PCBM-supported preparation route. (c) Device construction of PSC using hybrid PCBM – absorber film, (d) cross-section TEM image of established PSC, and (e) top-view SEM figure of as-prepared perovskite absorber produced using chlorobenzene (CB)-supported method.160 Three different PSCs comprising of single perovskite layer, perovskite/PCBM bilayer, and polymerized formula designed by Zhong et al. using temperature-based chronoamperometric examination and by dropping ionic motion the enhanced activation energy was noticed (reproduced with permission from ref. 161.
