TL;DR: Addition of 4-tert-butylpyridine to redox electrolytes used in dye-sensitized TiO2 solar cells has a large effect on their performance, and the working mechanism can be summarized.

TL;DR: In this article, a two-step deposition technique was used for preparing CH3NH3PbI3 perovskite solar cells using ZrO2 and TiO2 as a mesoporous layer, achieving an efficiency of 10.8% and 9.5% under 1000 W m−2 illumination.

TL;DR: The solar-to-electric power-conversion efficiency of dye-sensitized solar cells can be improved by integrating a mesoporous, nanoparticle-based, 1D photonic crystal as a coherent scatt... as discussed by the authors.

TL;DR: In this paper, a micellar solution of 3,4-ethylenedioxythiophene (EDOT) was applied to conducting glass and flexible plastic substrates using a simple, scalable pr...

TL;DR: In this article, the authors investigated the physical and chemical origin of the reversible bleaching and recrystallization mechanism of hybrid lead halide perovskite CH3NH3PbI3 and showed that it can be understood from a frustrated Lewis pair formation with a partial electron donation of the lone-pair on nitrogen together with competitive bonding to other species.
