Abstract

Improved photovoltaic cells utilizing for a semiconductor layer titanium dioxide powders, consisting of porous particles, which range in size from 0.1 to 10 microns and possess relatively high bulk density combined with a high surface area. Said particles are aggregates of crystallites having a size of less than 0.1 micron.
