Concentrating photovoltaic solar power generation and heating machine

Abstract

The invention belongs to the field of solar energy development and utilization and particularly relates to a concentrating photovoltaic solar power generation and heating machine. The concentrating photovoltaic solar power generation and heating machine comprises a solar energy lens group condensation system, a power generation system, a heating system and a tracking system, wherein the solar energy lens group condensation system forms a lens group by a monomer convex lens through an array combination; the power generation system adopts an III-V group semiconductor cell capable of bearing condensing illumination with 1000 times, and thus generates the same electric energy relative to a crystal silicon chip by using few III-V group semiconductor cells; and the tracking system has a function of real-time and automatic tracking of the solar optical axis so as to obtain the maximum energy efficiency value of the solar energy. The problem of heat dissipation of the concentrating photovoltaic cells is a technical problem always puzzled in the industry. The invention adopts a technical scheme using water cooling heat dissipation, which can fundamentally solve the problem and reliably obtain the conversion energy of two kinds of solar energy, namely power generation and heat supply, as well as change the final conclusion that you can't have your cake and eat it.

Description

technical field [0001] The invention belongs to the field of solar energy development and utilization, in particular to a concentrating photovoltaic solar power generation and heat supply machine. Background technique [0002] The sun is a very huge energy source, and the optical power it sends to the earth is only 120,000 TW. Compared with this, the total energy consumption of human society is about 13TW, and the installed capacity of power generation in the world is less than 4TW, which is much smaller than the light power sent by the sun to the earth. The corresponding energy of all oil resources on the earth is only equivalent to the light energy supplied to the earth by the sun in a day and a half. Furthermore, due to the energy crisis and concerns about environmental pollution, some developed countries began to invest in industrial development of solar energy as early as the 1970s. my country is one of the countries rich in solar energy resources. my country has a d...

Problems solved by technology

Solar cells have been developed to the current third-generation technology. Domestic Sanan Optoelectronics has achieved 1,000 times the concentration of light. The corresponding DBC uses AlN material with a higher thermal conductivity than Al2O3. However, the large amount of heat generated after concentration suppresses The regular operation of chips has become an urgent problem to be solved for concentrator collectors
