The invention discloses a solar frequency-division combined power generation device. The solar frequency-division combined power generation device comprises a semi-transparent perovskite solar cell, a Fresnel lens, a condensation reflection mirror and an inorganic solar cell, wherein electric conduction silica gel is arranged on a lower surface of the semi-transparent perovskite solar cell by vacuum molding to form the Fresnel lens, sunlight is incident from an upper surface of the semi-transparent perovskite solar cell, solar spectrum of 300-800 nanometers is absorbed in the semi-transparent perovskite solar cell, and solar spectrum of 800-2,500 nanometers will be condensed on the inorganic solar cell by the condensation reflection mirror. By the solar frequency-division combined power generation device, the photovoltaic power generation efficiency of the semi-transparent perovskite solar cell is effectively improved, the light spot distribution uniformity is improved by the condensation reflection mirror, the efficiency of the inorganic solar cell is improved, and the inorganic solar cell is prevented from being damaged due to an overheat point.

Description

technical field [0001] The invention belongs to the field of solar power generation, in particular to a solar frequency division composite power generation device. Background technique [0002] There are currently two main technical approaches to convert solar energy into electrical energy. One is to use energy conversion materials to directly convert solar energy into electrical energy, such as solar photovoltaic cells and thermoelectric semiconductor devices; -Electrical conversion, the former is currently developing rapidly. Traditional silicon-based solar cell technology has achieved large-scale commercial applications, but its cost performance is currently unable to compete with traditional energy sources. Research and develop high conversion efficiency and low-cost solar power generation technology It is still an important issue that needs to be solved urgently in the field of solar energy utilization. [0003] Since the production cost of perovskite battery modules i...

Problems solved by technology

The spectral energy outside the wavelength range will increase the thermal load of solar cells and reduce the efficiency of the cells. While reducing the unit power generation cost, it is also limited by the resources of sunlight and cannot break through the dilemma of low solar radiation energy density.
