摘要: A solar cell structure (1) and a method of its fabrication, the structure comprising an array of elongated nanowires (2) made in a semiconductor material having a direct band gap. Each nanowire (2) has at least a first (3) and a second (4) sections. Said structure comprises a first electrode layer (7) realizing ohmic contact to at least one portion of each first section (3), a second, optically transparent electrode layer (8) realizing contact to at least one portion of each second section. Each nanowire (2) comprises a minority carrier barrier element (6) for minimizing recombination of minority carriers at the contact to the second electrode layer (8).
