Thienyl Self-Assembled Molecule Enabled Stable Perovskite/TOPCon Silicon Tandem.
In mixed-component wide bandgap (WBG) perovskites, the elusive (111) crystal orientation confers enhanced operational stability compared to the conventional (100) orientation, yet typically compromises photovoltaic performance, presenting a critical stability-efficiency trade-off that remains unresolved. We report a th...
