Comparative Performance Analysis of Dye Sensitized Solar Cells

Photovoltaic energy conversion is today a very hot topic. The technical solutions are already on the market, the silicon crystalline or amorphous being the most used solar cells. We present in the paper investigations on a promising different type of solar cell called Dye-sensitized solar cell (DSSC)[1]. This cell presents different construction and operation principles from silicon cells and is presented as a possible solution for large area or flexible panels. We present here electrical measurements on three DSSC prototype samples, compared with a commercial silicon cell, for different illumination levels. The voltage-current characteristics and the main parameters of the cells, as short circuit current, open circuit voltages, maximum power point (MPP) are comparatively presented in the paper.
