TL;DR: In comparison with typical CH3NH3PbI3-based devices, these solar cells without encapsulation show greatly improved stability in humid air, which is attributed to the incorporation of thiocyanate ions in the crystal lattice.

TL;DR: Semitransparent perovskite solar cells are prepared by laminating graphene transparent electrodes on the top for the first time and show high power conversion efficiencies when they are illuminated from both sides.

TL;DR: The fabrication of air-stable FASnI3 solar cells is reported by introducing hydroxybenzene sulfonic acid or its salt as an antioxidant additive into the perovskite precursor solution along with excess SnCl2 along with the interaction between the sulfonate group and the Sn2+ ion.

TL;DR: The first report of low-voltage high-gain phototransistors based on perovskite/organic-semiconductor vertical heterojunctions, which show ultrahigh responsivities and specific detectivities in a broadband region from the ultraviolet to the near infrared are presented.

TL;DR: In this article, the performance of organic solar cells is substantially enhanced by introducing high-mobility conjugate polymers as additives for the first time, and the most pronounced effect is observed in one type of device with the average power conversion efficiencies increased from 8.75% to 10.08% after the addition of a highmobility polymer for only 0.5 weight percent in the active layers.
