TL;DR: In this article, the role of light trapping and angular restriction in improving the maximal output power of thin-film perovskite photovoltaics has been clarified and the influence of trap-assisted nonradiative recombination on the device efficiency is investigated.

TL;DR: Vacuum-assisted thermal annealing is demonstrated as an effective means for controlling the composition and morphology of the CH(3)NH( 3)PbI(3), which significantly improves the device stability and reproducibility with a standard deviation of only 0.92% in PCE as well as strongly reducing the photocurrent hysteresis.

TL;DR: In this article, a novel NFG system is proposed by introducing ultrathin monolayer graphene as well-defined sub-nanospacer between Ag NPs and Ag film (named G(graphene)-NFG system).

TL;DR: In this paper, a simple post-device ligand (PDL) treatment was proposed to improve the long-term stability of metal halide perovskite solar cells (PVSCs).

TL;DR: This work proposes and demonstrates an approach through a low-cost, robust, room temperature and room atmosphere process to fabricate a conductive silver nano- network comprising silver nanowires and silver nanoparticles, and demonstrates the feasibly transferrable silver conductive nano-network as the top electrode in organic solar cells.
