LPI-Europe scientists publish technical paper in Optics Express

    Leading scientists at LPI’s Spanish subsidiary in Madrid have published a new paper presenting an advanced and patent pending Concentrated Photovoltaic (CPV) design called the LPI Fresnel- Köhler. The design is comprised of a four-quadrant Fresnel primary lens and a four-node secondary refractive element. The article is published in the latest issue of Optics Express, a peer-reviewed rapid-publication scientific, electronic journal published by the Optical Society of America. One task in achieving a competitive edge in the mass production of concentrated photovoltaics is to incorporate a sufficiently large Tolerance Budget. This optical budget can be used to compensate for system tracker errors, allow for optics manufacturing sloppiness, misalignments and other imperfections of the assembly process or simply to relax these tolerances making the manufacturing process more economical. In their article, the authors detail their development of the optical device and cover its attributes and advantages.
