摘要
Researchers working in the field of photovoltaic are exploring novel materials for the efficient solar energy conversion. The prime objective of the discovery of every novel photovoltaic material is to achieve more energy yield with easy fabrication process and less production cost features. Perovskite solar cells (PSCs) delivering the highest efficiency in the passing years with different stoichiometry and fabrication modification have made this technology a potent candidate for future energy conversion materials. Till now, many studies have shown that the quality of active layer morphology, to a great extent, determines the performance of PSCs. The current and potential techniques of solvent engineering for good active layer morphology are mainly debated using primary solvent, co-solvent (Lewis acid-base adduct approach) and solvent additives. In this review, the dynamics of numerously reported solvents on the morphological characteristics of PSCs active layer are discussed in detail. The intention is to get a clear understanding of solvent engineering induced modifications on active layer morphology in PSC devices via different crystallization routes. At last, an attempt is made to draw a framework based on different solvent coordination properties to make it easy for screening the potent solvent contender for desired PSCs precursor for a better and feasible device.
