This review focuses on the development of lead-free non-toxic perovskite materials based solar cells and other devices. To solve the lead associated toxicity problem, lead can be substituted with nontoxic and environmentally friendly metals like Ti, Sn, Sb, Ge, Bi, and Ag.
Scientists at Oxford University have developed a solvent system with reduced toxicity that can be used in the manufacture of perovskite solar cells, clearing one of the barriers to the commercialisation of a technology that promises to revolutionise the solar industry.
Dr Nakita Noel of Oxford’s Department of Physics, lead author of the study, said: 'At the moment, there are three main solvents used in the manufacture of perovskite solar cells, and they are all toxic, which means you wouldn't want to come into contact with them.
Although the use of non-toxic perovskite NCs in solar cells is quite recent, they have already shown promising results surpassing in some cases the efficiency values obtained for their bulk counterparts: CsSnI 3 quantum rods show an efficiency of almost 13% (bulk material 7.5%), and CsGeI 3 NCs an efficiency close to 5% (bulk material ≈3%).
Perovskites are widely studied as components of solar cells but their synthesis often involves toxic reagents. Here lead-free bismuth-based perovskites are synthesised using a non-toxic solvent and shown to achieve power conversion efficiencies of up to 1.62 % under 1 sun illumination for up to 300 h.
The toxicity issue of lead-based halide perovskites hinders theirs large-scale commercial applications in solar cells. A variety of non- or low-toxic perovskite materials have been used for development of environmentally friendly lead-free perovskite solar cells, some of which show excellent optoelectronic properties and device performances.
