TLDR
In this article, a simple organic trisiloxane molecule (denoted as TSi) was applied to modify solgel ZnO (sg-ZnO) films.Abstract:
Organic solar cells (OSCs) simultaneously featuring good photovoltaic performance and strong humidity resistance are greatly anticipated for their practical application. Herein, we developed a simple organic trisiloxane molecule (denoted as TSi), and applied it to modify sol–gel ZnO (sg-ZnO) films. Compared to pristine sg-ZnO films, the TSi/sg-ZnO film presents fewer surface defects, shallower work function, and stronger hydrophobicity. Benefiting from those improved characteristics, when adopting a benzodifuran (BDF)-based polymer (BDFP-Bz) and Y6 as the electron donor and acceptor to fabricate OSCs, the derived devices utilizing TSi/sg-ZnO as the electron transport layer (ETL) showed suppressed charge recombination, enhanced charge extraction and increased stability to moisture versus the devices based on an sg-ZnO ETL. Meanwhile, PBDFP-Bz:Y6 OSCs based on a TSi/sg-ZnO ETL delivered a higher PCE of 14.62% than that of the control devices (12.39%). More importantly, the TSi/sg-ZnO ETL was also applicable in other different photovoltaic systems, among which PM6:Y6 OSCs based on a TSi/sg-ZnO ETL yielded a superior PCE of 16.37% along with stronger stability to moisture versus the reference ones. Our finding demonstrates the TSi/sg-ZnO bilayer ETL holds promise in the practical application of OSCs for simultaneously improving the photovoltaic performance and moisture-resistance of devices.read more
