Abstract: The present invention relates to a method for packaging solar cell receivers having secondary optical elements. The present invention adopts a mold having mold cavities with special shapes. By filling mold cavities with optical encapsulant, the substrate containing solar cells is placed upside down towards the mold. Then the solar cells are immersed into the optical encapsulant before curing. Then, the cured optical encapsulant has the characteristics of the secondary optical elements and thus can be used as secondary optical elements such as spherical lenses. Meanwhile, the packaging of the solar cells is completed as well. The overall process requires only one curing process, which reduces the packaging time substantially.

Abstract: The present invention relates to a structure of concentrating solar cell module with reduced height, which includes multiple partitions and reflection mirrors. The solar cell receiver is attach to a surface of the partition and rotated by 90 degrees. After the reflection leans against a surface of another partition, the light concentrated by the concentrating lens can be redirected from vertical incidence to horizontal incidence. Then the redirected light is focused at the 90-degree rotated solar cell receiver for performing energy conversion. This structure avoids the limitation of the concentrating solar cell module by the focal distance of the concentrating lens. Thereby, the height of the module is reduced substantially; the volume of the module becomes thinner and the weight thereof becomes lighter and thus facilitating installation and transportation.

Abstract: A concentrator solar receiver with an improved homogenizer is revealed. A homogenizer used in a concentrator solar module is improved. Instead of a smooth flat surface, a bottom surface of the homogenizer can be a positively curved surface, a conic solid, or a truncated tapered structure. Moreover, the bottom surface can be a rough surface. Thus not only the glue-overflow problem occurred during adhesion of the homogenizer to the solar cell can be solved, but also the possibility of air bubbles remaining between the glue and the homogenizer is reduced. Therefore the yield rate of a concentrator solar module is improved and the service life of the concentrator solar module is prolonged.
