Micro optics for micro hybrid concentrator photovoltaics

Concentrating photovoltaics (CPV) systems use concentrating optical elements to significantly reduce the material and processing costs of multi-junction high efficiency solar cells and improve the conversion efficiency. However, several issues hindered the development of CPV technologies due to the fundamental limit of thermodynamics and practical difficulties of manufacturing and deployment, such as system bulkiness, tight tracking error, thermal management and inability to collect diffuse irradiance. By dramatically scaling down the dimensions of the cells to the level of hundreds of microns and accordingly the concentrating optics, micro hybrid CPV overcomes the listed issues and also delivers a small form factor module prole similar to conventional at panel PV. In this thesis, we are focusing on the critical optical components in the micro hybrid CPV: the micro optics. First, we demonstrated a wafel-level micro hybrid CPV module based on Si fabrication.
