It's a cover up! A new organic dye self-assembled on ZnO surface through carboxylate bonding has positive effects on the photovoltaic performance of inverted polymer solar cells (PSCs). This dye is based on a D–π–A system and can mediate forward charge transfers, reduce back charge recombination, passivate ZnO surface defects, and give good energy level alignments leading to largely enhanced efficiency and stability in inverted PSCs.
