▎ 摘 要
NOVELTY - The new type utility claims a welding for low loss photovoltaic cell , which comprises base layer as the aluminum belt (1), the aluminum belt (1) positive and opposite two side formed with graphene (2), the graphene (2) positive and opposite two side formed with rough surface (3), the rough surface (3) is covered with upper tin layer (4), the tin layer (4) is set up with solar energy absorption coating layer (5), aluminum belt (1) of the cross section is transverse H shape. Relative to the traditional welding, the utility model is new type using graphene to replace copper foil, make the solar energy battery reduce cost, increase power generation efficiency, with good flexibility, high intensity, not easy breaking and; aluminum with surface processing into rough surface, using the external light is light receiving rate forming diffuse reflection, increase cell plate of the synchronous increase photoelectric conversion rate.
