MONOCRYSTALLINE PERC TECHNOLOGY

Perc battery assembly composition

The battery assembly comprises a substrate layer, the top surface of which is sequentially provided with, from bottom to top, a diffusion layer, an SiOx positive passivation layer, and an SixNy positive anti-reflection passivation protective film layer, and the bottom surface of which is sequentially provided with, from top to bottom, an SiOx back passivation layer, an AlOx back passivation film layer and an SixNy back anti-reflection passivation protective film layer, characterized in that the SixNy positive anti-reflection passivation protective film layer has a thickness of 75-95 nm, and a refractive index of 2.08-2.13; the SixNy back anti-reflection passivation protective film layer has a thickness of 90-160 nm, a number of film layers of at least two, and a refractive index in the layer closest to the substrate layer of ≥2.1; and the AlOx back passivation film layer has a thickness of 2-28 nm, and a refractive index of 1.56- 1.76.

Energy storage liquid cooling battery cabinet technology development

In this paper, the box structure was first studied to optimize the structure, and based on the liquid cooling technology route, the realization of an industrial and commercial energy storage thermal management scheme for the integrated cabinet was studied to ensure that the temperature between the cabinets was consistent and reduce the system capacity loss caused by the liquid-cooled battery module was inconsistent.
