Abstract: Sodium induced shunting continues to be a challenging issue in crystalline Si solar modules. Potential-Induced Degradation of the Shunting type (PID-s) has been linked to Na, but the source is unclear. In this paper we evaluate the ion migration kinetics in encapsulant material under operational conditions.
This is also a major reason why most CZTSSe solar cells use soda-lime glass as the substrate. [35 - 37] Specifically, when using soda-lime glass as the substrate, under high-temperature conditions, Na diffuses toward the absorber layer. This diffusion behavior promotes the growth of CZTSSe grains and passivates interface defects.
Before spin-coating, the cleaned Mo-coated substrates were preheated for 10 min to increase the Na content in the Mo surface layer (the absence of a SiO 2 barrier layer in the Mo layer does not affect the upward diffusion of Na from the soda-lime glass).
Subsequently, a Na-free precursor solution was spin-coated onto the Mo-coated soda-lime glass substrates and heated at 300 °C for 2 min to form the precursor film; the film prepared under these conditions served as the reference sample and was named Pre-0.
Our standardized solar power and energy storage products are engineered for reliability, safety, and efficient deployment. All systems include comprehensive monitoring and control systems with remote management capabilities.
