1. Poly+ annealing mechanism ① Depositing a tunneling oxide layer (SiO₂) and a doped amorphous silicon layer on the back to form a selective carrier transport channel (enabling electron tunneling and hole blocking). ② Annealing process: high temperature crystallization of amorphous silicon layer, activation of P phosphorus doping and reduction of contact resistance. 2. Factors […]
Solar manufacturers announced a range of module sales agreements, supply deals and new products last week at SNEC 2025 PV Expo in Shanghai. GCL System Integration (GCL SI) joined China’s Tiangong LCA Data Platform, becoming the first major photovoltaic manufacturer to participate in the national carbon data initiative. The company’s move follows its earlier collaboration […]
*BC module prices in China are now split into ground-mounted and C&I segments; residential and C&I prices are also included for Europe. Polysilicon Buyers, still holding some polysilicon inventory, are pushing prices down to RMB 30–34/kg, with some indications of offers dipping below RMB 30/kg. However, no large-volume deals have been finalized at these levels. […]
