耐热钙钛矿-硅叠层太阳能电池研制成功

Core Insights - Researchers at the National University of Singapore have developed a heat-resistant perovskite-silicon tandem solar cell with a power conversion efficiency exceeding 34% and maintained performance after 1200 hours of continuous operation at 65°C [1][2] Group 1: Technology Development - The new tandem solar cell combines silicon with perovskite materials to enhance power generation efficiency by absorbing more sunlight in the same area [1] - Previous studies attributed performance degradation to the perovskite material itself, but recent findings indicate that the issue lies in the ultra-thin molecular layer connecting the perovskite and silicon layers [1] Group 2: Performance Testing - The newly developed solar cell features a novel self-assembled monolayer (SAM) that significantly improves performance, achieving a power conversion efficiency of over 34% [2] - In high-temperature conditions, the solar cell retains over 96% of its initial performance after 1200 hours of continuous operation, which is a remarkable achievement in the field of perovskite solar cells [2]
