棱柱形钙钛矿太阳能电池（Prim PVSC）旨在减轻传统单个单元电池的热力学损失。通过引导光的流动，具有高到低能量的太阳光子可以分别被四个子电池捕获，这些子电池具有不同但匹配的MAPbIxBr3− x薄膜带隙。这是首款采用四个串联子电池的Prim PVSC，产生创纪录的5.3 V电压和21.3%的高PCE，为打破PVSC的PCE瓶颈提供了新方法。
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.
