Abstract

The invention relates to an aluminium-based circuit board of a concentrating photovoltaic photoelectric conversion receiver, and belongs to the technical field of solar power generation. The aluminium-based circuit board of the concentrating photovoltaic photoelectric conversion receiver comprises an aluminium-based circuit board substrate, a concentrating photovoltaic cell chip soldering area, an etch trench, a circuit negative electrode, a negative electrode wiring area, a circuit positive electrode, a positive electrode wiring area and a small circular blind hole array. The aluminium-based circuit board substrate is divided into the circuit positive electrode and the circuit negative electrode through the etch trench, a corresponding positive electrode connecting area and a corresponding negative connecting area are arranged on the circuit positive electrode and the circuit negative electrode respectively, the concentrating photovoltaic cell chip soldering area, the positive electrode connecting area, the negative connecting area and the small circular blind hole array are arranged on the aluminium-based circuit board substrate, the aluminium-based circuit board substrate comprises an aluminum base layer, an insulating layer, a copper layer, a nickel layer and a gold layer, the aluminum base layer is arranged on one face of the insulating layer, the other face of the insulating layer is covered with the copper layer, the other face of the copper layer is covered with the nickel layer, and the other face of the nickel layer is covered with the gold layer. On the premise that rapid heat transmission is guaranteed because of thicknesses of all material layers of the aluminium-based circuit board substrate, it is guaranteed that the circuit board is not prone to deformation in subsequent processing and fixing processes of the circuit board, and therefore the soldering yield of concentrating photovoltaic cell chips is improved; bypass diodes are omitted from the aluminium-based circuit board substrate, and therefore material cost and processing cost of products are reduced.

Description

technical field [0001] The invention relates to a photovoltaic power generation component, in particular to an aluminum-based circuit board for a concentrated photovoltaic photoelectric conversion receiver, which belongs to the technical field of solar power generation. Background technique [0002] In the concentrating photovoltaic power generation system, the most important component is the concentrating photovoltaic photoelectric conversion receiver circuit board, which acts as a carrier for electronic components such as concentrating photovoltaic cells, and quickly reduces the high temperature on the surface of the concentrating photovoltaic cells (above 150 ℃) Temperature) is quickly transmitted to the heat sink, so there are higher requirements for the receiver circuit board material, heat transfer material, process, etc. At present, the material layer used in many concentrating photovoltaic photoelectric conversion receiver circuit boards is too thin, which is prone t...
