Prismatic perovskite solar cells (Prim PVSC) were designed to mitigate thermodynamic losses of traditional single unit cells. By guiding the flow of light, the solar photons with high-to-low energy could be captured separately by the four subcells with varied, yet matched, bandgaps of MAPbIxBr3−xfilms. This is the first Prim PVSC with four series subcells that generates a recordVocof 5.3 V and a high PCE of 21.3%, providing a new method for breaking the PCE bottleneck of PVSCs.

AbstractDeposition of perovskite films by antisolvent engineering is a highly common method employed in perovskite photovoltaics research. Herein, we report on a general method that allows for the fabrication of highly efficient perovskite solar cells by any antisolvent via manipulation of the antisolvent application rate. Through detailed structural, compositional, and microstructural characterization of perovskite layers fabricated by 14 different antisolvents, we identify two key factors that influence the quality of the perovskite layer: the solubility of the organic precursors in the antisolvent and its miscibility with the host solvent(s) of the perovskite precursor solution, which combine to produce rate-dependent behavior during the antisolvent application step. Leveraging this, we produce devices with power conversion efficiencies (PCEs) that exceed 21% using a wide range of antisolvents. Moreover, we demonstrate that employing the optimal antisolvent application procedure allows for highly efficient solar cells to be fabricated from a broad range of precursor stoichiometries.
