TL;DR: A reversible photo-induced instability has been found in mixed-halide photovoltaic perovskites that limits the open circuit voltage in solar cells.

TL;DR: In this article, the authors observe slow transient effects causing hysteresis in the current-voltage characterization of hybrid organo-metal halide perovskites that can lead to an over- or underestimation of the solar cell device efficiency.

TL;DR: A semiconductor that can be processed on a large scale with a bandgap around 1.8 eV could enable the manufacture of highly efficient low cost double-junction solar cells on crystalline Si.

TL;DR: In this paper, a transparent silver nanowire electrode was used on perovskite solar cells to achieve a semi-transparent device, which was placed in a mechanically-stacked tandem configuration onto copper indium gallium diselenide (CIGS) and low-quality multicrystalline silicon (Si) to achieve solid-state polycrystalline tandem solar cells with a net improvement in efficiency over the bottom cell alone.

TL;DR: A robust buffer layer is introduced by solution-processing AZO nanoparticles, enabling a sputtered amorphous ITO layer without damaging the underlying device.
