Publication number: 20150136210Abstract: Solar devices with high resistance to light-induced degradation are described. A wide optical bandgap interface layer positioned between a p-doped semiconductor layer and an intrinsic semiconductor layer is made resistant to light-induced degradation through treatment with a hydrogen-containing plasma. In one embodiment, a p-i-n structure is formed with the interface layer at the p/i interface. Optionally, an additional interface layer treated with a hydrogen-containing plasma is formed between the intrinsic layer and the n-doped layer. Alternatively, a hydrogen-containing plasma is used to treat an upper portion of the intrinsic layer prior to deposition of the n-doped semiconductor layer. The interface layer is also applicable to-multi-junction solar cells with plural p-i-n structures. The p-doped and n-doped layers can optionally include sublayers of different compositions and different morphologies (e.g., microcrystalline or amorphous).Type: ApplicationFiled: May 10, 2013Publication date: May 21, 2015Inventors: Xavier Multone, Daniel Borrello, Stefano Benagli, Johannes Meier, Ulrich Kroll, Marian Fecioru-Morariu
