Abstract

The invention belongs to a light-concentrating photovoltaic-temperature difference power-generating integrated device, and comprises a light-concentrating battery component, a liquid cooling device, a thermal collecting device, and a bismuth telluride-based thermoelectric generator. The light-concentrating photovoltaic-temperature difference power-generating integrated device is characterized in that: the light-concentrating battery component consists of a monocrystalline silicon solar battery and a columnar light-concentrating lens on the upper part of the monocrystalline silicon solar battery; the bottom of the monocrystalline silicon solar battery is bonded on a ceramic substrate by a heat conductive silicon chip; the ceramic substrate is connected with the liquid cooling device, and the liquid cooling device consists of a circulatory cooling passage, a water pump and a radiator. One side of the circulatory cooling passage is connected with the ceramic substrate at the bottom of the monocrystalline silicon solar battery, and the other side is connected with the radiator; the circulatory cooling passage is connected with the water pump; a top ceramic chip of the thermoelectric generator is bonded on the radiator of the liquid cooling device by adhering to a heat conductive silicon chip. The invention has the advantages that the waste heat generated by the monocrystalline silicon solar battery during the light-concentrating photovoltaic power generation can be recycled, therefore the efficiency of the overall light-concentrating photovoltaic power generation is improved substantially.

Description

technical field [0001] The invention belongs to a concentrating photovoltaic-thermoelectric power generation integrated device. Background technique [0002] In recent decades, with the rapid development of global science and technology and economy, the problems of energy shortage and environmental degradation have become increasingly prominent. In order to reduce the dependence on traditional fossil energy, renewable energy, especially solar power generation technology, has attracted widespread attention. The most widely used solar cells in the world are monocrystalline silicon and polycrystalline silicon solar cells, and their total output accounts for about 80% of solar cell output. Crystalline silicon solar cells have high conversion efficiency and reliability, and the manufacturing process has been very mature after years of development. Compared with traditional power generation methods, the disadvantage of crystalline silicon solar cells is that the cost of power gen...
