摘要： A method of fabricating a densified nanoparticle thin film with a set of occluded pores in a chamber is disclosed. The method includes positioning a substrate in the chamber; and depositing a nanoparticle ink, the nanoparticle ink including a set of Group IV semiconductor particles and a solvent. The method further includes heating the nanoparticle ink to a first temperature between about 30° C. and about 300° C., and for a first time period between about 5 minutes and about 60 minutes, wherein the solvent is substantially removed, and a porous compact with a set of pores is formed. The method also includes heating the porous compact to a second temperature between about 300° C. and about 900° C., and for a second time period of between about 5 minutes and about 15 minutes, and flowing a precursor gas into the chamber at a partial pressure between about 0.1 Torr and about 50 Torr, wherein the precursor gas substantially fills the set of pores, and wherein the densified nanoparticle film with the set of occluded pores is formed.

摘要： A method for fabricating thin film solar cells for a concentrated photovoltaic system uses three shadow masks. The first mask, used to deposit a back contact layer, has multiple horizontal and vertical lines defining columns and rows of cells, and multiple tabs each located in a cell along a center of a vertical border. The second mask, used to deposit a CIGS absorption layer, a window layer and a transparent contact layer, is similar to the first mask except the tabs are located along the opposite vertical border of the cells. The third mask, used to deposit a metal grid layer, has multiple bus bar openings and finger openings. Each bus bar opening is located along a horizontal center line of a cell and overlaps the second tab of a neighboring cell. The cells in a horizontal row are connected in series, forming a linear solar receiver.

摘要： A low cost concentrating photovoltaic system includes a condenser system having refractive or reflective optics and a photovoltaic module having one or more thin film solar cells. The thin film solar cells may be a-Si, CdTe, Cu(InGa)Se2, organic solar cell or dye sensitized solar cells. The condenser system may be a flat, cylindrical or hemispherical Fresnel lens, a parabolic reflector, a compound parabolic concentrator, a reflective V-trough, or a combination thereof. The condenser system has a concentration ratio of about 10 to 100 or higher. No tracking system is needed in many examples, or a simple one-axis tracking may be used. In one example, the condenser system uses a hemispherical Fresnel lens which focuses sunlight onto a hemispherical focal surface, and one thin film solar cell (mounted on a tracking unit) or multiple cells (without tracking) are disposed on the hemispherical focal surface of the Fresnel lens.
