Abstract
Optical and electronic properties of polycrystalline bulk and thin‐film CuInSe2‐based photoelectrochemical solar cells have been evaluated. The minority‐carrier diffusion length was measured using the surface photovoltage technique and polyiodide electrolyte yielding 1 and 0.8 microns for n‐type bulk and thin‐film material, respectively. The first bulk optical absorption data have been obtained from transmission, using thinned samples and Fourier transform infrared spectroscopy techniques. These confirm high optical‐absorption coefficients (4×105 cm−1) away from threshold.Keywords
