TL;DR: The demonstration of switchable OTP photovoltaics and electric-field-manipulated doping paves the way for innovative solar cell designs and for the exploitation of OTP materials in electrically and optically readable memristors and circuits.

TL;DR: The reduced grain boundary area and improved crystallinity dramatically reduce the charge recombination in OTP thin films to the level in OTB single crystals.

TL;DR: In this article, an interdiffusion method was proposed to fabricate pinhole free perovskite films using a low temperature solution process, achieving an efficiency of 15.4% with a fill factor of ∼80%.

TL;DR: In this paper, a combination of nanoscopic and macroscopic level measurements was used to show that ion migration in polycrystalline perovskites dominates through grain boundary (GBs).

TL;DR: In this article, the influence of methylammonium iodide/lead iodide precursor ratio on perovskite film morphology and device performance was studied and the unique double fullerene layers adopted could dramatically reduce dark current leakage by forming a Schottky junction with the anode, and effectively increase the efficiency by boosting the fill factor to above 80%.
