Abstract

The invention relates to a solar system comprising a reflection unit, a heat energy absorber and a first solar panel. The reflection unit is provided with a first energy gap solar cell and a reflection surface to reflect or converge sunlight; the reflection unit converts sunlight with a wave length shorter than or equal to x nanometer into electric energy according to the first energy gap solar cell and reflects or converges sunlight with a wave length longer than x nanometer to the heat energy absorber and the first solar panel; the heat energy absorber converts sunlight which is reflected by the reflection unit and has a wave length longer than or equal to y nanometer into heat energy; the heat energy absorber is provided with a first surface, liquid and a second surface; the liquid is positioned between the first surface and the second surface; and the first solar panel is provided with a second energy gap solar cell to convert sunlight which penetrates through the heat energy absorber and has a wave length shorter than or equal to z nanometer into electric energy, wherein y is larger than or equal to z, and z is larger than x.

Description

technical field [0001] The invention relates to an energy system, in particular to a solar energy system. Background technique [0002] Solar energy is an inexhaustible and non-polluting energy. It has always been the focus of attention when solving the pollution and shortage problems faced by current petrochemical energy. Since the solar panel (solar panel) has a photovoltaic cell (photovoltaic cell, PV cell), the solar panel can directly convert light energy into electrical energy. However, how to make full use of sunlight to achieve better photoelectric conversion efficiency is a very important research topic at present. [0003] Generally speaking, the photoelectric conversion efficiency of solar panels made of silicon-based materials is usually 20-30%. The main reason is that it is usually limited by the energy gap that can be absorbed and converted to 1.1 electron volts, that is, the central wavelength of the sunlight it absorbs is less than 1100nm, and when the wave...
