Effect of formulas of titanoxide compositions on the photovoltaic characteristics of solar cells

Abstract

The effect the chemical composition of semiconductor titanium compositions (titanium pastes) has on the photovoltaic characteristics of dye-sensitized solar cells is investigated. It is established that the efficiency of solar energy conversion by a photovoltaic cell made with Ti-nanooxide D paste is 5.3%, while that of one made with Degussa P25 paste is 4.7%. These data correlate with the specific surface and sorption ability of semiconductor films.
