A new free-form Köhler concentrator is presented that combine high geometric concentration, high acceptance angle and high irradiance uniformity on the solar cell. This is achieved by modifying the optical surfaces to produce Köhler integration. Although the new optical surfaces (that is, the ones including Köhler integration) behave optically quite different from the old ones, but from the macroscopic point of view they are very similar to the old ones. This means that they can be manufactured with the same techniques (typically plastic injection molding or glass molding) and that their production cost is the same i.e., with a high potential for low cost and high optical efficiency. The present approach is completely new and allows keeping the acceptance angle at high values and the concentration factor without increasing the number of optical elements. The simulated optical performance of a Köhler integrating solar concentrator is presented. This concept is the first combining non flat array of Köhler integrators with concentration optics. | |
