Abstract: Quantum dot sensitised solar cells (QDSSC) is generally fabricated using transparent conducting (TCO) glass plates and platinum or gold as electrodes. The article reports a modified back side illuminated QDSSC structure utilising aluminium foil as electrodes. PbS quantum dots have been synthesised using simple chemical method and are utilised as sensitisers in a ZnO-based solar cell structure. Two types of QDSSCs are fabricated using the same quantum dots, i.e., one using ITO glass plate and the other using aluminium. The solar cell parameters are obtained for both the structures and their comparative analysis is reported in the paper.

Keywords: PbS; quantum dots; sensitiser; solar cell; modified structure; back illumination; aluminium electrode.
