A concentrated photovoltaic solar device

Abstract

The invention discloses a concentrating photovoltaic solar device. The concentrating photovoltaic solar device comprises a reflecting mirror structure (2), a photovoltaic cell device (6), a radiator (11) and a cover lens (5), wherein the reflecting mirror structure (2) comprises a reflecting mirror (3); the photovoltaic cell device (6) is respectively arranged on the special position of the reflecting mirror structure (2) for directly receiving light rays converged by the corresponding reflecting mirror (3); the arranged position of the radiator (11) does not affect a reflecting light path, and is close to or partly superposed with the reflecting mirror structure (2); the cover lens (5) is arranged in front of the reflecting mirror structure (2), wherein the reflecting mirror structure (2) and the cover lens (5) form a closed space; and the photovoltaic cell device (6) is arranged in the closed space. The concentrating photovoltaic solar device has reliable performance, is high in strength, low in cost and long in service life, and can be installed in the form of an array, and can be applied in a large-scale manner.

Description

technical field [0001] The invention relates to a concentrated photovoltaic solar energy device. Background technique [0002] As a kind of clean and environment-friendly energy, solar energy has been devoted to its development and utilization for a long time. Especially in recent years, due to the rising oil price and the improvement of environmental protection requirements, as well as the limitation of atmospheric carbon dioxide emissions, countries have worked harder to carry out research on solar energy utilization, which is critical to the key components of solar energy application equipment, especially It is the efficiency of solar energy reception and the manufacturing cost that put forward higher requirements. Concentrating photovoltaics has the advantage of greatly reducing battery consumption, but currently there are problems with high optics, heat dissipation, and tracking costs. There are mainly two types of optical concentrating systems: transmission concentra...
