Sandia's CONCEPT-90 photovoltaic concentrator module

Chiang, C.J.

A description is given of Sandia's CONCEPT-90 module, which represents a novel type of point-focus photovoltaic concentrator module designed for improved safety, reliability, and performance, and for ease of component fabrication and module assembly. These improvements will combine to decrease the cost of electricity produced by this type of concentrator module. Unique features of the CONCEPT-90 module include encapsulated cell assemblies, simple flat components, and integral use of plastics. The first prototype of this module has been made using back-contact silicon concentrator cells and refractive secondary optical elements. The first prototype module is described, and results from outdoor tests are presented.
