A simple but effective method for improving the perovskite film quality by adding bidentate halogenated additives into the precursor solution of perovskite was proposed. By comparing and analyzing the effects of the use of different additives on the film-forming performances, DIO was selected as the optimal additive. The optimal additive amount of DIO could contribute to a more uniform and non-defective growth of perovskite crystal nucleation, enabling preparation of the smooth and compact film with large grain size. The effect mechanism of the chelation between DIO and Pb2+ on the film-forming process of perovskite crystal was also analyzed. The PCE of the PSC device incorporating the DIO is runned up to 19.1%, accounting for a 73.6% enhancement as compared to pre-optimized control PSCs. Conclusively, using the proposed technology, the conversion efficiency of the prepared 5 cm×5 cm device reaches up to 11.2%, which can be applicable to the preparation of large-area perovskite solar cells. © 2017

This article described a dual plasmonic effect on improving the performance of polymer solar cells (PSCs). We blended respectively silver nanoparticles (AgNPs) of different sizes into the anode buffer layer and the active layer to trigger localized surface plasmon resonance (LSPR), which enhanced the broadband absorption of the PSCs. We adopted double anode buffer layers to reduce the surface roughness of the composite buffer layer, which ensured the electrical properties of the PSCs. Finally, we led to the realization of a polymer solar cell with a power conversion efficiency of 9.2%, accounting for a 21.7% enhancement as compared to pre-optimized control PSCs. These results suggest a new approach to achieve higher overall enhancement through the cooperative plasmonic effect aroused from dual resonance enhancement of two different nanoparticles. © 2014 Published by Elsevier Ltd.
