Organic (opto) electronic materials have received considerable attention due to their
applications in thin-film-transistors, light-emitting diodes, solar cells, sensors, photorefractive …

Solar cells have provided a solution to the prevailing energy crisis and environmental
contamination in the ongoing energy-driven era because of their potential to utilize solar …

Among the parameters that characterize a solar cell and define its power-conversion
efficiency, the fill factor is the least well understood, making targeted improvements difficult …

The rapid pace of development for hybrid perovskite photovoltaics has recently resulted in
promising figures of merit being obtained with regard to device stability. Rather than relying …

Three different theoretical approaches are presented to identify pathways to organic solar
cells with power conversion efficiencies in excess of 20%. A radiation limit for organic solar …

The recombination of electrons and holes is a major loss mechanism in photovoltaic devices
that controls their performance. We review scientific literature on bimolecular recombination …

Recombination in bulk heterojunction organic solar cells based on polycarbazole/fullerene
blends are studied through measurements of the solar-cell response. Different …

Photoelectronic properties of orthorhombic undoped κ-Ga2O3 epitaxial thin films, grown on
sapphire substrates by metal–organic vapour phase epitaxy, were evaluated under X-ray …

The performance of organic photodetectors is steadily improving, and the specific detectivity,
as a key figure of merit, has reached values of 1012–1013 Jones, ie, comparable to that of …

We utilize transient techniques to directly compare the operation of polymer/fullerene,
polymer/nanocrystal, and polymer/polymer bulk heterojunction solar cells. For all devices …
