Scientists build 33.3%-efficient perovskite-silicon tandem solar cell processed in ambient air
Chinese researchers developed a PNCC polymer hole-transport layer that enables efficient and stable perovskite solar cells to be fabricated under ambient conditions. The material was used in a perovskite-silicon tandem cell that achieved 33.3% efficiency and a certified efficiency of 33.0%.
Researchers build 27.39%-efficient inverted perovskite solar cell based on new molecular design
Chinese researchers have developed a molecular additive that reduces defects in perovskite solar cells, enabling a power conversion efficiency of 27.39%. The approach was also used in bifacial mini-modules with efficiencies above 22% and 99.6% power retention after more than 5,000 hours of continuous operation.
New research confirms negligible LeTID degradation in TOPCon solar cells
Researchers have found that light- and elevated-temperature-induced degradation (LeTID) has a limited impact on n-type TOPCon solar cells compared with earlier p-type PERC technology. Optimized firing conditions and laser-enhanced contact optimisation can further suppress degradation, with industrial TOPCon cells showing efficiency losses within acceptable warranty tolerances.
