Molecular Additive Defect Passivation
Designer additives and self-assembled monolayers control perovskite crystallisation and passivate bulk, grain-boundary and buried-interface defects while preserving charge extraction, raising inverted-cell efficiency and operational lifetime together.
Developed mainly in: China and Hong Kong SAR ChinaImpacting: Europe, Rest of Asia, China and North America
Teams at City University of Hong Kong, Jilin University and Sun Yat-sen University built an inverted perovskite solar cell using a hole-extraction layer made from three structurally similar carbazole-naphthalene self-assembled molecules. The mixed-packing, high-entropy film delivered 27.31% certified steady-state efficiency, a 27.5% champion cell, and almost no degradation after 1,300 hours at 85°…
