LIGHT TRAPPING TECHNIQUE FOR DYE SENSITIZED SOLAR CELL

Dye Sensitized Solar Cells (DSSC) possess huge potential in solar energy utilisation. Immense research has been carried out in order to improve its performance. This paper suggests an alternative way of employing Light Trapping technique on DSSC by dry etching substrates before depositing the transparent conductive oxide (TCO) layer on one of the electrodes. The result demonstrated a decrease in reflectance before depositing the TCO, but an increase in reflectance after depositing the TCO. Texturing might also help to increase the effective surface area at the interface between various cell layers, providing a shorter path for the electron transport layer and improving collection efficiencies.
