Abstract
The influence of the thickness reduction of bifacial solar cells has been investigated using Czochralski (Cz) substrates with thicknesses of 140 and 240 mum. Thickness reduction has increased cell performance for both illumination modes, and unlike the conventional structure, the thin one presents higher efficiency when illuminated by the n+n junction. The good light trapping properties and low rear recombination have revealed efficient once the influence of bulk recombination is reduced thanks to thinning.
