Title:
TITANIUM DIOXIDE FILMS FOR PHOTOVOLTAIC CELLS
Document Type and Number:
WIPO Patent Application WO1999065045
Kind Code:
A3
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.
