Description

This report describes the project by Energy Conversion Devices, Inc. (ECD) and its American joint venture, United Solar Systems Corp. (United Solar), to develop and commercialize a roll-to-roll triple-junction amorphous silicon alloy PV manufacturing technology. This low material cost, roll-to-roll production technology has the economies of scale to meet the cost goals necessary for widespread use of PV. ECD developed and built the present 5-MW United Solar manufacturing plant in Troy, Michigan, and is now designing and building a new 25-MW facility, also in Michigan. United Solar holds the world's record for amorphous silicon PV conversion efficiency, and manufactures and ... continued below

Description

This report describes the project by Energy Conversion Devices, Inc. (ECD) and its American joint venture, United Solar Systems Corp. (United Solar), to develop and commercialize a roll-to-roll triple-junction amorphous silicon alloy PV manufacturing technology. This low material cost, roll-to-roll production technology has the economies of scale to meet the cost goals necessary for widespread use of PV. ECD developed and built the present 5-MW United Solar manufacturing plant in Troy, Michigan, and is now designing and building a new 25-MW facility, also in Michigan. United Solar holds the world's record for amorphous silicon PV conversion efficiency, and manufactures and markets a wide range of PV products including flexible portable modules, power modules, and innovative building-integrated PV (BIPV) shingle and metal-roofing modules that take advantage of this lightweight, rugged, and flexible PV technology. All of United Solar's power and BIPV products are approved by Underwriters Laboratories and carry a 10-year warranty. ECD and United Solar are addressing issues to reduce the cost and to improve the manufacturing technology for the ECD/United Solar PV module manufacturing process. ECD and United Solar identified five technology development tasks that would reduce the module manufacturing cost in the present 5-MW production facility and would also be applicable to future larger-scale manufacturing facilities. These development tasks are: Task 5: Improved substrate heating and monitoring systems; Task 6: The development of new on-line diagnostic systems; Task 7: Development of new back-reflector deposition technology; Task 8: Development of improved RF PECVD reactor cathode and gas distribution configurations; and Task 8A: Development of new pinch valve technology.
