20150122324 | THIN-FILM PHOTOVOLTAIC DEVICE WITH OPTICAL FIELD CONFINEMENT AND METHOD FOR MAKING SAME - A photovoltaic device is provided that includes a first electrode layer and a second electrode layer; and a waveguiding structure disposed between the first electrode layer and the second electrode layer which includes an active layer adapted to convert photons transmitted to the active layer to electrons and holes. The waveguiding structure further includes a first layer adjacent the first electrode layer that includes a hole-conducting material having a first index of refraction, and a second layer including an electron-conducting material having a second index of refraction, wherein the active layer is disposed therebetween. The active layer has an index of refraction that is less than each of the first index of refraction and the second index of refraction and a thickness. The waveguiding structure is characterized by guided modes adapted for optically confining the photons within the active layer. | 05-07-2015 |

20140041504 | Mechanical Method For Producing Micro- Or Nano-Scale Textures - A mechanical method for producing micro-scale and nano-scale textures that facilitates, for example, the cost-effective production of nanostructures on large-scale substrates, e.g., during the large-scale production of thin-film solar cells. A “scratcher” (multi-pointed abrasion mechanism) is maintained in a precise position relative to a target substrate such that micron-level features (protrusions) extending from the scratcher's base structure are precisely positioned to contact a surface material layer of the target substrate with a predetermined amount of force, and then moved relative to the substrate (e.g., by way of a conveying mechanism) while maintaining the pressing force such that the micron-level features define elongated parallel nano-scale grooves and/or form nano-scale ridges in the surface material layer (i.e., by mechanically displacing) portions of the surface material layer to form the nano-scale grooves/ridges). | 02-13-2014 |
