Tetrahydrotriazinium stabilizes perovskite film for enhanced solar cell performance

Summary

KAUST researchers have demonstrated that incorporating tetrahydrotriazinium into perovskite/silicon tandem solar cells enhances both performance and stability. The additive increases hydrogen bonds in the perovskite film's crystal structure, improving power conversion efficiency to 33.7% and phase stability during testing under intense conditions. The improved cells showed more stability after 1500 hours of testing, modeling harsh environments. Why it matters: This research offers a pathway to more durable and efficient solar cells suitable for deployment in harsh climates like the Arabian Peninsula, potentially boosting renewable energy adoption in the region.
