TL;DR: The fabrication of a-Si:H nanowires and nanocones function as both absorber and antireflection layers, which offer a promising approach to enhance the solar cell energy conversion efficiency.

TL;DR: A semiconductor that can be processed on a large scale with a bandgap around 1.8 eV could enable the manufacture of highly efficient low cost double-junction solar cells on crystalline Si.

TL;DR: For a wide range of photovoltaic devices based on polymer:fullerene, small-molecule:C60 and polymer:polymer blends, the study reveals that the internal quantum efficiency is essentially independent of whether or not D, A or CT states with an energy higher than that of CT1 are excited.

TL;DR: It is shown that for typical OPVs, precise knowledge of the real part of the complex index of refraction is not required for the active layer absorption, and it is critically important to take this parasitic absorption into account when calculating internal quantum effi ciency.

TL;DR: This work focuses on replacing conductive metal oxides with alternative materials that can be deposited from solution and can reproduce the performance of metal oxide on glass on various substrates, including plastics.
