TL;DR: A sequential deposition method for the formation of the perovskite pigment within the porous metal oxide film that greatly increases the reproducibility of their performance and allows the fabrication of solid-state mesoscopic solar cells with unprecedented power conversion efficiencies and high stability.

TL;DR: In this article, a two-step spin-coating procedure was used to control the size of the cuboid cuboid of CH(3)NH(3)-PbI(3), achieving an average efficiency exceeding 16% and best efficiency of 17%.

TL;DR: Th Thin CuSCN films can replace organic hole-transporting layers that limit thermal stability of devices and demonstrate PSCs that achieve stabilized efficiencies exceeding 20% with copper(I) thiocyanate (CuSCN) as the hole extraction layer.

TL;DR: This work shows that the goal of extending the optical-absorption onset of perovskite-based photovoltaics further into the red to enhance solar-light harvesting can be reached by using a mixture of formamidinium and methylammonium cations, which leads to an enhanced short-circuit current and thus superior devices to those based on only CH3 NH3 (+).

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.
