Five-year, 5 GW partnerships aim to bring high-efficiency perovskite-TOPCon hybrid solar technology to India by 2028.

Caelux Partners with Navitas Solar and Rayzon Solar to Advance Next-Generation Solar Modules.

US-based Caelux Corporation has signed separate five-year, 5 GW commercialisation agreements with Navitas Solar and Rayzon Solar to develop next-generation hybrid tandem solar modules in India. The partnerships will integrate Caelux’s proprietary perovskite energy-generating glass with advanced N-type TOPCon technology, enabling module efficiencies of 28% or higher. Commercial production is targeted for 2028, supporting India’s push for advanced domestic solar manufacturing. The innovative technology replaces conventional module glass with a power-generating perovskite layer, increasing power output from the same installation area. Navitas Solar said the collaboration will strengthen its manufacturing roadmap and position India among the early adopters of hybrid tandem modules. Rayzon Solar highlighted that the partnership will help meet India’s ambitious 500 GW renewable energy target by 2030 through high-efficiency, locally manufactured products. Caelux described India as a strategic market for expanding its next-generation solar technology on a global scale.
