Organic solar cells pros and cons: Outlooks toward semitransparent cell efficiency and stability

Organic solar cells (OSCs) are promising for low emissive photovoltaic technology. Excitonic absorption and charge generation to transport process OSC energy loss lessening central. In this context, donor–acceptor barrier offset, related binding, thermal effect on the key challenge. Semitransparent organic cell visible band transmission near infrared anticipated. Near in a Si material is higher that supports more conversion. Moreover, greater carrier selectivity open circuit voltage (Voc) incredible increase efficiency. utmost but transfer state offset increases recombination loss. Upon analysis of small molecule donors polymers along with non-fullerene previously studied fullerene acceptors, it realized active morphology, thickness, interface design impending overcome For efficiency–transparency trade-off as well stability problem purpose thin materials interface, their tenability main requisites. scope, very acceptors ternary blend heterostructures innovative-transparent hole layers can play vital role. Therefore, transparency absorbent layer transparent electrodes hetero-interface predominant field over reported efficiency scope.
