Abstract: A Kesterite film is vacuum deposited and annealed on a substrate. Deposition is conducted at low temperature to provide good composition control and efficient use of metals. Annealing is conducted at a high temperature for a short period of time. Thermal evaporation, E-beam evaporation or sputtering in a high vacuum environment may be employed as part of a deposition process.

Abstract: PROBLEM TO BE SOLVED: To provide a solar energy alignment and collection system that facilitates tracking and improves the efficiency of collection. SOLUTION: A solar energy alignment and collection system includes at least two solar energy receivers having a central focal point, with each of the at least two solar energy receivers generating an energy output. An actuation system is operatively coupled to the at least two solar energy receivers and is configured and disposed to shift the solar energy receivers along at least one axis. A control system, operatively linked to the solar receivers and the actuation system, senses the energy output of each solar energy receiver and shifts the actuation system along the at least one axis causing solar energy to be directed at the central focal point. When solar energy is directed at the central focal point, the energy output of each solar energy receiver is substantially identical. COPYRIGHT: (C)2011,JPO&INPIT
