Comparative Studies of Temperature Influence on Characteristics of Dye Sensitized and Silicon Based Solar Cells

This paper continues our investigations on dye-sensitized solar cells (DSSCs), or Grätzel cells, presented in references [1] and [2]. We will present the influence of temperature on the current-voltage characteristics of DSCC produced after a proprietary process, and for comparison, we will measure in identical conditions some selected commercial silicon-based photovoltaic cells. Derived parameters such as short-circuit current, open-circuit voltage, fill factor, maximum power point, series resistance, and parallel resistance will also be presented. The results of the research will contribute to the development of the DSCC production process, with a focus on the materials. In this study, we have tested four different solar cells at various temperature conditions: an amorphous silicon solar cell designed for indoor applications produced by Panasonic, a silicon based solar cell, a dye-sensitized solar cell with a structure based on titanium dioxide that was produced by our colleagues from the National Institute of Research and Development for Electrochemistry and Condensed Matter, in Timisoara, by following the procedures in [2] and [3], and a flexible solar cell for indoor applications produced by PowerFilm Solar.
