The collaboration leverages Rayzon Solar’s 11.3 GW manufacturing capacity in Surat to scale hybrid tandem modules, which combine traditional silicon with perovskite technology. This design increases power density by allowing the top glass of a solar panel to act as a secondary electricity generator. According to Caelux CEO Scott Graybeal, the initiative serves as a strategic entry point for the company to scale its technology globally, targeting the Indian government’s utility tenders by 2028.

For Rayzon Solar, the deal strengthens its domestic manufacturing footprint under the 'Make in India' initiative. The company is currently commissioning a 5.1 GW TOPCon cell plant to support the project. Rayzon CEO Amit Barve noted that the partnership provides the necessary scale to reach India’s goal of 500 GW of clean energy capacity by 2030. By combining Caelux’s proprietary glass with established TOPCon production lines, the firms intend to improve the levelized cost of electricity, positioning their modules as a high-performance alternative to conventional silicon-only panels.
