Abstract

Atmospheric pressure Chemical Vapour Deposition has been used to deposit polycrystalline thin films of SnO2:F on aluminium foil. This foil is used commercially as a temporary substrate in the production of flexible solar cells. The resulting thin films were characterised and fabricated into a-Si:H/mc-Si:H tandem solar cells. These devices gave promising initial energy conversion efficiencies up to 7.5% and high current densities. Spectral response measurements showed good blue response indicating sufficient transparent conducting oxide/p-interface and excellent current values for the bottom cell as a result of the high quality of the SnO2:F.
