Model SOL9410S & SOL9411 - Front-side Metallization Paste for Mono and Multicrystalline Wafers
From Front-side Pastes
In the race for superior quality and increasing efficiencies, solar cell manufacturers turn to Heraeus to set them apart from their competition. Heraeus has established itself as the leading PV paste developer, as well as the highest quality supplier, through delivering the best performance to cost ratio on the market. SOL9410S and SOL9411 are new generation front-side silver metallization pastes that build on our impressive track record. Optimized for high efficiency and high throughput processing, SOL9410S and SOL9411 were formulated to exceed the quality of our benchmark pastes, SOL9235H and SOL9273MA, in every aspect. The unique chemistry of SOL9410S and SOL9411 enhance the etch of the SiNXH anti-reflective coating, thus, significantly improving contact while preserving the junction quality on various emitters and wafers. SOL9410S and SOL9411 are optimized for varying emitter depths and concentrations.
