Abstract: The photovoltaic properties of Schottky barrier solar cells made from thin films (100–1000 A) of the organic dye hydroxy squarylium have been studied. Amorphous and polycrystalline films, prepared by evaporation and solution casting, have strong absorption over the entire visible spectrum. The highest power conversion efficiency measured under AMO white light was 0.1% (0.14 mW/cm2 input intensity); this decreased to 0.02% at 135 mW/cm2. The decrease in η with intensity is characteristic of organic materials, but is usually much more pronounced. For 8500‐A monochromatic light the quantum efficiency was as high as 2.3% and the conversion efficiency was 0.2% (1 mW/cm2).

TL;DR: In this article, the maximum attainable efficiency for the conversion of solar energy into electric energy was calculated as a function of the two semiconductor band gaps, E g 1 and E g 2, and of two material parameters, a 1 and a 2.

TL;DR: In this article, annealing Cu•plated AgInSe2 samples in Se at temperatures between 200 and 500°C were used for photovoltaic detectors with peak quantum efficiency of 0.18 near 1.15 μ.
Abstract: p‐type Cu2Se/n‐type AgInSe2 heterodiodes were fabricated by annealing Cu‐plated AgInSe2 samples in Se at temperatures between 200 and 500°C. When operated as photovoltaic detectors, the diodes exhibit a peak quantum efficiency of 0.18 near 1.15 μ.
