Abstract

The invention discloses reflective glass glaze ink and a method for manufacturing a photovoltaic glass panel by using the reflective glass glaze ink. The method comprises the following steps: sprayingink on a glass back plate by adopting an industrial inkjet printing method according to a preset pattern; melting and bonding glass glaze on the glass back plate through curing, heating and baking; and manufacturing the photovoltaic glass panel according to a conventional photovoltaic module production process. The method adopts a non-contact process, has no tension deformation of a screen printing screen plate, has high graphic position precision, and maximizes component area utilization; at the same time, different screen plates for products with different specifications, sizes and patternsare not needed, the photovoltaic glass panel can be prepared directly through digital editing, modification and inkjet printing, and the method has low cost and high efficiency.

Description

Technical field [0001] The invention relates to the field of solar photovoltaic technology, and more specifically to a reflective glass glaze ink and a method for manufacturing photovoltaic glass panels using the ink. Background technique [0002] Solar energy is a kind of renewable energy. In today's economic globalization, all mankind has a strong desire for energy and the environment, and the installed capacity of photovoltaic power plants is also increasing. At present, renewable energy accounts for about 25% of the total global energy, and there is still a huge potential. With the approaching of photovoltaic parity online, explosive growth is bound to occur in the future. Photovoltaic parity grid access requires the joint efforts of the upstream and downstream of the photovoltaic industry chain to improve the conversion efficiency of solar cells and modules on the one hand, and reduce the production cost of each link on the other hand. As far as photovoltaic cells and modu...
