摘要： Methods and apparatus are provided for converting electromagnetic radiation, such as solar energy, into electric energy with increased efficiency when compared to conventional solar cells. A photovoltaic (PV) unit, according to embodiments of the invention, may have a very thin absorber layer produced by epitaxial lift-off (ELO), all electrical contacts positioned on the back side of the PV device to avoid shadowing, and/or front side and back side light trapping employing a diffuser and a reflector to increase absorption of the photons impinging on the front side of the PV unit. Several PV units may be combined into PV banks, and an array of PV banks may be connected to form a PV module with thin strips of metal or conductive polymer applied at low temperature. Such innovations may allow for greater efficiency and flexibility in PV devices when compared to conventional solar cells.

摘要： Methods and apparatus are provided for converting electromagnetic radiation, such as solar energy, into electric energy with increased efficiency when compared to conventional solar cells. A photovoltaic (PV) device may incorporate front side and/or back side light trapping techniques in an effort to absorb as many of the photons incident on the front side of the PV device as possible in the absorber layer. The light trapping techniques may include a front side antireflective coating, multiple window layers, roughening or texturing on the front and/or the back sides, a back side diffuser for scattering the light, and/or a back side reflector for redirecting the light into the interior of the PV device. With such light trapping techniques, more light may be absorbed by the absorber layer for a given amount of incident light, thereby increasing the efficiency of the PV device.

摘要： Methods and apparatus are provided for converting electromagnetic radiation, such as solar energy, into electric energy with increased efficiency when compared to conventional solar cells. In one embodiment of a photovoltaic (PV) device, the PV device generally includes an n-doped layer and a p+-doped layer adjacent to the n-doped layer to form a p-n layer such that electric energy is created when electromagnetic radiation is absorbed by the p-n layer. The n-doped layer and the p+-doped layer may compose an absorber layer having a thickness less than 500 nm. Such a thin absorber layer may allow for greater efficiency and flexibility in PV devices when compared to conventional solar cells.

摘要： Embodiments of the invention generally relate to a method for selectively etching or otherwise removing copper or other metallic contaminants from a substrate, such as a gallium arsenide wafer. In one embodiment, a method for selectively removing metallic contaminants from a substrate surface is provided which includes exposing a substrate to a peroxide clean solution, exposing the substrate to a hydroxide clean solution, and exposing the substrate to a selective etch solution containing potassium iodide, iodine, sulfuric acid, and water during a selective etch process. The substrate generally contains gallium arsenide material, such as crystalline gallium arsenide, and is usually a growth substrate for an epitaxial lift off (ELO) process. The copper or other metallic contaminants disposed on the substrate may be selectively etched at a rate of about 500 times, about 1,000 times, about 2,000 times, or about 4,000 times or greater than the gallium arsenide material.
