Abstract
A high concentration photovoltaic (HCPV) optics are described. In one example, an HCPV device can include a frame and a solar sensor cell attached to the frame. The solar cell can be configured to receive an optical beam and can further be configured to convert solar energy in the incident optical beam into electrical energy or power. The HCPV device can further include a non-imaging freeform optical device. The optical device can have an asymmetric surface profile with a predefined surface normal arranged to direct incident optical beams toward an entire solar sensor cell surface area. The freeform optical device can have a larger diameter than the solar sensor cell. Also, the freeform optical device can have an asymmetric surface profile shaped to concentrate the incident optical beams onto the solar sensor cell.
