TL;DR: Analysis of the current-voltage (J-V) characteristics at various light intensities provides information on the different recombination mechanisms in the BHJ solar cells with different thicknesses of the Ca layer, revealing that the J-V curves are dominated by first-order recombination from the short-circuit condition to the maximum power point and evolve to bimolecular recombination in the range of voltage in the optimized device with a Ca thickness of 20 nm.

TL;DR: The ZnO layer used to improve the light-harvesting increases the charge collection efficiency, serves as a blocking layer for holes, and reduces the recombination rate and the combined optical and electrical improvements raise the power conversion efficiency to 8.9%, comparable to that of polymer counterparts.

TL;DR: In this article, the authors reported an efficient inverted bulk-heterojunction with a highly transparent sol-gel derived ZnO film as electron selective layer and MoO3 as hole selective layer.

TL;DR: In inverted structure small-molecule (SM) solar cells with an efficiency of 7.88% are demonstrated using ZnO and PEIE as an interfacial layer and are relatively stable in air compared to conventional cells.

TL;DR: A sandwich tunnel system separated by functionalized glass spacers is designed to induce capillary action for controlling the polymer nanostructure, crystallinity, and charge transport and creates a promising pathway toward high performance, solution processable, and low-cost organic electronics.
