Abstract

The progress made by the scientific community in emerging photovoltaic technologies over the past two decades has been outstanding. Numerous methods have been developed for the preparation of hybrid organic–inorganic perovskite solar cells. The power conversion efficiency has been up to 14% by a one-step vacuum deposition technique. A serious concern is the toxicity of the materials. In this review, several methods aimed at resolving these problems to some extent have been compiled, including eco-friendly synthesis. Further efficiency enhancements are expected following optimization, and a better fundamental understanding of the internal electron charge transfer, electron–hole diffusion to the corresponding layers, flexibility, and stability-dependent bandgaps is reported. This paper explores the green synthesis of organic–inorganic perovskites for industrialization. Concerning the above facts, a simple low-cost model called “dispersed photovoltaic cells” is presented.


Highlights:


1 Fourth-generation perovskite materials prevail in terms of efficiency (21%) and low-cost green synthetic routes.
2 A serious concern is the toxicity of materials. Lead-free, highly efficient, relatively moisture stable, and environmentally friendly synthetic routes could be performed.
3 Highly mobile charge carriers, low exciton binding energy, low rate of recombination, and charge transportation make perovskites a more challenging field.
