Very high efficiencies have been demonstrated under concentration with silicon solar cells having interdigitated contacts on the backside. However, only laboratory cells of small dimension have reached very high efficiencies. The need for developing a multilevel metallization technology for back contact concentrator solar cells of large area is demonstrated. The particular features …

Photovoltaic power generators utilizing focused sunlight allow the two stringent requirements for terrestrial photovoltaic systems, i.e. low cost and high performance, to be met with two separate elemets. Passive optical elements function as low cost large-area collectors while small-area single-crystal solar cells serve as high efficiency energy converters.

High-efficiency concentrators will be stiff competition for other PV technologies in medium-scale p ower applications in good solar-resource regions [2]. However, even though some applications favor PV concentrator over flat-plate systems, or vice versa, the most significant competition in the U.S. for either is natural gas.

However, their efficiency is somewhat lower, as the flat design does not concentrate light as precisely as a parabola. These concentrators require less maintenance, but like parabolic troughs, they depend on direct sunlight. Linear Fresnel concentrators typically reach temperatures between 250°C and 300°C and are of a somewhat simpler design.
