Opportunities of electrical technologies for control of the quality parameters of light sensitive materials

Based on the obtained experimental results, an algorithm of the information and measurement system for operational control of the efficiency of photocells during their operation is proposed. The subject of the research was solar radiation energy converters into electric current energy - photocells from the wide -band semiconductor titanium oxide and polymethine dyes - sensitizers, which are sensitive to the action of light in the visible and near -infrared bands of the solar spectrum. Using the method of immittance spectroscopy, information on transport and recombination electronic processes was obtained, which was used to assess the potential for the construction and use of the investigated quality systems of solar cells. The object of the study is the dependence of the quality control parameter of the photocell - the titanium oxide content - on the value of the measured electrical parameter - admittance. Control of the efficiency of photocells is offered by the sign (positive or negative) of the value of the measured electrical parameter - complex conductivity.
