| Abstract: | We report a facile approach to prepare metal oxides for the interfacial layer in polymer solar cells (PSCs), in which the precursor solutions were obtained by dissolving commercial metal oxide/hydroxide in ammonia water. This approach can be adopted as a general method to prepare various solution-processable metal oxides for interfacial layers in PSCs, such as MoOx, VOx, WOx and ZnOx. The photovoltaic performance of PSCs buffered by these metal-oxide layers was studied and the applicability of these interfacial layers was demonstrated both with P3HT and a low band-gap polymer PBDT-T8-TPD. |
