Solar cells based on perovskites, calcium titanium oxide minerals or compounds with similar structures, are among the most promising emerging energy solutions. Over the past few years, engineers and material scientists have been exploring the potential of solar mini-modules (i.e., small cells that can be used to create larger-scale solar panels) made of perovskite bifacial structures.
As suggested by their name, these flat structures have perovskite materials on both their front and back side, with the first harvesting direct sunlight and the latter light that is reflected on surfaces (i.e., albedo light). While solar mini modules based on perovskite bifacial structures could achieve greater power conversion efficiencies (PCEs) than conventional perovskite solar cells, effectively designing them has so far proved challenging.
