    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： Embodiments of the invention generally relate to epitaxial lift off (ELO) thin films and devices and methods used to form such films and devices. In one embodiment, a method for forming an ELO thin film is provided which includes depositing an epitaxial material over a sacrificial layer on a substrate, adhering a flattened, pre-curved support handle onto the epitaxial material, and removing the sacrificial layer during an etching process. The etching process includes bending the pre-curved support handle to have substantial curvature while peeling the epitaxial material from the substrate and forming an etch crevice therebetween. Compression is maintained within the epitaxial material during the etching process. The flattened, pre-curved support handle may be formed by flattening a pre-curved support material.
