Polycrystalline Silicon
Discover what polycrystalline silicon is and its crucial role in solar power. Learn about its production, applications, advantages, and future prospects in renewable energy.
Polysilicon: The Key Material for the Solar Industry
Polysilicon is one of the most commonly used materials for manufacturing solar cells. By slicing polysilicon into thin wafers, these wafers are then integrated into solar panels
Mitigating parasitic optical losses in bifacial TOPCon solar cells
In this work, we demonstrate a local thinning (LT) approach on the polysilicon (poly-Si) layer in TOPCon cells to mitigate parasitic absorption. The LT approach is achieved by combining
