Problems solved by technology

This is an improvement to the existing technology, but it fails to solve the problem that when the solar collector is deviated relative to the sun, a part of the focused sunlight will run away from the solar cell, and this problem of light loss will reduce the efficiency of the solar collector

Abstract

A solar collector comprises a concentrator that focuses sunlight into concentrated light and a light receiver. The light receiver includes a concave photovoltaic cell structure connected to reflecting surfaces. The concave photovoltaic cell structure is made of a concave photovoltaic cell, or multiple flat photovoltaic cells forming a concave shape, or a photovoltaic cell and its mirror images forming a virtual concave shape. The reflecting surfaces are oriented to reflect light onto the photovoltaic cell. Each reflecting surface may be a mirrored wall of a mirror or the side-wall of a reflecting prism. A heat pipe may be attached to the light receiver and a transparent container may encase the concentrator and the light receiver. The container may be sealed from the environment, contain an insulating gas, or be held under a vacuum.

Description

technical field [0001] The invention relates to a solar device, the light is irradiated by a concentrator to a concave receiving surface formed by one or more photovoltaic cells with a reflective surface, so as to generate electricity and heat. Background technique [0002] Existing photovoltaic systems have not achieved the highest efficiency that their solar cells can achieve, because after the sunlight is concentrated, the rays are no longer parallel but have a relatively large scattering angle, while existing high-efficiency solar cells require sunlight to be roughly vertical And evenly irradiated on its surface to achieve its highest efficiency. A prior invention patent application (US2011 / 0226308, solar hybrid module) proposed a solution to improve efficiency by attaching solar cells to polygonal heat pipes. This is an improvement to the prior art, but it fails to solve the problem that when the orientation of the solar collector is deviated relative to the sun, a par...
