TL;DR: Heavy doped inorganic charge extraction layers in planar PSCs were used to achieve very rapid carrier extraction, even with 10- to 20-nanometer-thick layers, avoiding pinholes and eliminating local structural defects over large areas.

TL;DR: In this article, a new record efficiency (11.4%) of dye-sensitized solar cell was obtained by design and syntheses of donor-acceptor type co-adsorbents which effectively overcome the competitive light absorption by I−/I3−, avoid dye aggregation, and reduce the charge recombination.

TL;DR: A new deposition route for methyl ammonium lead halide perovskite films that does not rely on use of a common solvent or vacuum, and relies on the rapid conversion of amine complex precursors to perovkite films, followed by a pressure application step to overcome the substantial reduction in power conversion efficiency when a small device is scaled up.

TL;DR: An additive-engineering strategy is developed to realize a facile and convenient fabrication method of large-area uniform perovskite films composed of large crystal size and low density of defects, which is found to simultaneously enhance the PCE and the durability of PSCs.

TL;DR: The constructed heterostructure can selectively extract photogenerated charge carriers and impede the loss of decomposed components from soft perovskites, thereby reducing damage to the organic charge-transporting semiconductors.
