Abstract
The absorption of a large fraction of the incident solar radiation by the p hotoactive layer of dye-sensitized, liquid-junction photovoltaic cells is a n important factor for achieving useful photoelectric conversion efficienci es. A model is presented that estimates the enhancement of optical absorpti on that can be obtained from light scattering in the porous nanocrystalline films used in these cells and from reflection at the back electrode. The m odel is applied to the optical characterization of two films, a transparent , and a strongly scattering porous titania sample. (C) 1999 Elsevier Scienc e B.V. All rights reserved.
