Process for cleaning substrate of high-power condensation solar energy photoelectric receiver

Abstract

The invention relates to a process for cleaning a substrate of a high-power condensation solar energy photoelectric receiver and belongs to the technical field of solar photovoltaic power generation. The process comprises the steps that a manufacturing technologist places the high-power condensation solar energy photoelectric conversion receiver on a special aluminum tray, places the aluminum tray containing the substrate of the high-power condensation solar energy photoelectric conversion receiver on a plasma cleaning machine table, sets parameters of the plasma cleaning machine table, starts a power supply to clean the substrate, takes out the cleaned substrate and places the substrate into a nitrogen gas cabinet for storage and standby application. By the adoption of the process, the surface of the substrate of the high-power condensation solar energy photoelectric conversion receiver can have uniform cleanliness, and dirt and an oxidation layer on the surface of the substrate are processed effectively; better bonding performance can be achieved when a battery piece is bonded to the substrate; the rejection ratio of products can be greatly lowered, so the extra cost generated by repair or scrapping of the products can be controlled to the maximum extent.

Description

technical field [0001] The invention relates to a cleaning process, in particular to a cleaning process for a substrate of a high-power concentrating solar photovoltaic receiver, belonging to the technical field of solar photovoltaic power generation. Background technique [0002] The high-power concentrating solar photoelectric conversion receiver substrate, as its name is loyal, is a carrier for high-power concentrating solar cells and one of the core components of the high-power concentrating solar photoelectric conversion receiver. Since the core of the high-power concentrating solar cell is a high-efficiency GalnP / GalnAs / Ge triple-junction concentrating solar cell chip, when it is bonded to the high-power concentrating solar photoelectric conversion receiver substrate, a high-power concentrating solar photoelectric conversion receiver is formed. . But before bonding, it is very important to ensure the quality of the high-power concentrated solar photoelectric conversio...

AI Technical Summary

Problems solved by technology

Although the above methods are very effective, the surface coating of the substrate surface of the high-power concentrating solar photoelectric conversion receiver will be damaged invisibly, and the cleanliness of the substrate surface will be inconsistent. At the same time, it will also pollute the operating environment and cause secondary pollution to the product; When solar cells are bonded, bonding failures, bonding wires falling off, and false bonding often occur, resulting in difficulties in repairing, resulting in the scrapping of concentrating solar cells and substrates, thereby increasing the overall production cost of the product
