Novel photovoltaic diode and production process thereof

Abstract

The invention relates to the field of a photovoltaic diode and specially relates to a novel photovoltaic diode and a production process thereof. The photovoltaic diode is ingenious in structure, perfect and mature in process, high in product processing and production efficiency, good in heat radiation of the product, low in temperature rise and long in service life. The advantages are that the photovoltaic diode is ingenious in structure, perfect and mature in process, high in product processing and production efficiency, good in heat radiation of the product, low in temperature rise and long in service life; epoxy resin is injected from the large nail head surface and recoiled to the surface of a chip, thereby reducing the impact on the chip to the largest degree and reducing injection molding stress effectively; in the product using process, the contact surface between the chip and leading wires is increased, and the heat produced by the chip can be dissipated quickly, thereby reducing chip junction temperature, prolonging the service life of the product, and improving the rectification efficiency; and the design of annular round plates on the leading wires of the photovoltaic diode plays a mode locking effect in the processing process, and the mechanical strength of the product is enhanced after injection moulding.

Description

AI Technical Summary

Problems solved by technology

At present, photovoltaic diodes on the market are affected by their structure and have poor heat dissipation capacity, which leads to a rapid rise in temperature of existing photovoltaic diodes, which may deform the junction box of the solar module, resulting in a short service life of the entire module; therefore, it is necessary to meet the current solar energy requirements. Modules require photovoltaic diodes to have strong heat dissipation capabilities and long service life, etc., so photovoltaic diodes must be required to have the characteristics of novelty, high heat dissipation capability and long service life
