Organic–inorganic lead‐halide‐based perovskite solar cells (PSCs) have drawn tremendous attention due to their remarkable optoelectronic properties. The certified power conversion efficiencies (PCEs) of non-transparent solar cells have exceeded 22%. So far, there are only a few reports about the development of semitransparent perovskite solar cells. Although, these devices exhibited smaller power conversion efficiencies, they possess 20% transparency and less stability in ambient atmosphere.

We are trying to develop printable semitransparent perovskite-based solar cells, for industrial fabrication which would show enhanced efficiency at ambient atmosphere. We have used a novel technique which forms a semitransparent grid structure by self-assemble of perovskite precursor solution. The light absorbing active material has formed a grid pattern, composed of patterned arrays of transparent spots. To fabricate the fully printed semitransparent perovskite-based solar cells, a transparent insulating polymeric material was printed into the patterned arrays of the transparent spots by using inject printer. Using this protocol, we have developed printable semi-transparent perovskite based solar cells with resonable transparency which will have enhanced efficiency.
