Abstract (en)
[origin: WO2011138739A2] The invention relates to a photovoltaic cell (1) which includes at least one wafer (2) of a semi-conductor material, with a front surface (21) intended for receiving incident light and a back surface (22) opposite said front surface, as well as to methods for manufacturing said photovoltaic cell. The back surface (22) includes an electric contact (32) and a structure (4), referred to as an optical structure, which is discrete and capable of redirecting the incident light towards the core of the wafer.
