The yearly energy collection efficiency of stationary solar concentrators can be evaluated using reverse ray-tracing, and a solar radiation model. In reverse ray-tracing, rays originating at the receiver of the concentrator are traced towards the sur

Silicone-on-Glass (SOG) Fresnel lenses are flat optical elements used in concentrator photovoltaics (CPV). SOG lens production process broadly involves forming optical silicone prisms attached to glass. Silicone is first compressed onto glass while h

The CPV community is still undecided on one critical issue: what material to use best for Fresnel lens parquets. Reliability and longevity are the most important, but all other properties play roles as well. We have developed and manufactured Fresnel

Optics with high optical efficiency and reliability are the key components for CPV modules as well as high efficiency solar cells and a high accuracy tracker. The present paper describes the optical design, simulation and materials, including a direc

Complex systems like modules in concentrating photovoltaics (CPV) are designed in a systems approach. The better the components are concerted, the better the performance goals of the system can be fulfilled. Optics are central to the CPV module's rel

Secondary optics are used in concentrating photovoltaic (CPV) systems with Fresnel lens primaries to increase the optical system efficiency by catching refracted light that otherwise would miss the receiver, better the tracking tolerance (acceptance

Environmental stress cracking (ESC) begins with crazes on the surface of the plastic. Plastic optics may corrode due to ESC. Usually ductile, plastic may become brittle, and subject to failure due to mechanical, physical, or chemical influences. Stre

Collimating light is a common task in optical design. The smaller the source, the simpler the optics required for collimation. Small sources cannot emit sufficient power for some demanding applications. Larger sources are required. The physical limit

We describe optical test methods for indoor and outdoor assessment of concentrating photovoltaic (CPV) and concentrating solar power (CSP) plants and modules. Testing may be done in active mode, where the cell is driven in forward-bias mode, and pass
