Abstract

The invention belongs to a light-concentrating crystalline silicon solar battery component, which comprises a light concentrator, a monocrystalline silicon photovoltaic power generating device, a radiating and cooling device and a solar tracking device. The light-concentrating crystalline silicon solar battery component is characterized in that: a monocrystalline silicon solar battery is mounted on the solar tracking device; the upper part of the monocrystalline silicon solar battery is provided with the light concentrator, and the lower part of the monocrystalline silicon solar battery is provided with the radiating and cooling device. The invention has the advantages that: the light concentrating solar battery concentrates sunlight onto the solar battery by a light concentrating mirror; the conversion efficiency can be improved substantially through increasing the energy-flow density on the battery surface; and the usage amount of a material is reduced.

Description

technical field [0001] The invention belongs to a concentrating photovoltaic system using monocrystalline silicon as a power generation element, and uses a columnar concentrator to gather sunlight onto a monocrystalline silicon photovoltaic cell, which can significantly improve power generation efficiency, reduce battery material usage, and reduce power generation costs. Background technique [0002] The rapid progress of human society since the 19th century is based on the rapid development of fossil energy technology. Until now, the annual demand for fossil energy, mainly oil, coal, and natural gas, is still increasing. But this kind of energy on the earth is limited, and the fossil energy will be exhausted in the middle of the 21st century according to the current consumption rate. At the same time, the use of this type of fossil energy has had a wide range of serious impacts on humans and the natural environment. Therefore, green, pollution-free and renewable new energy...
