- The Solex Energy–ISC Konstanz partnership aims to advance back-contact solar module technology and strengthen India’s solar manufacturing capacity.
- Both companies will accelerate their R&D efforts, enhance solar cell performance, and promote sustainable innovation through this collaboration.
Solex Energy Ltd has partnered with Germany’s ISC Konstanz to enhance research and innovation in high-efficiency solar cell manufacturing. This Memorandum of Understanding marks a significant milestone in India’s rapidly growing solar technology sector.
Under the agreement, ISC Konstanz will offer full technological support to Solex Energy. Together, they will upgrade Solex’s upcoming TOPCon cell production line and integrate advanced back-contact and perovskite–silicon tandem technologies.
In addition, the partnership will help Solex build its own R&D line, supported by ISC Konstanz’s patent portfolio. As a result, the collaboration will strengthen India’s position in high-efficiency solar manufacturing and promote domestic innovation.
Chetan Shah, Chairman and Managing Director of Solex Energy Ltd, said, “This partnership represents a defining moment in Solex’s pursuit of excellence and leadership. Under our Vision 2030, we plan to make India a hub for solar innovation. We are targeting a ₹1 lakh crore valuation, $1.5 billion in planned investments, and a workforce of 25,000 skilled professionals.”
Meanwhile, Dr Radovan Kopeček, Head of Department Strategy and Education at ISC Konstanz, commented, “Since 2005, ISC Konstanz has focused on increasing photovoltaic efficiency while reducing costs. Our goal is to deliver research that benefits both industry and society. Partnering with Solex Energy takes us closer to a sustainable and affordable clean energy future.”
Solex unveiled the concept for its new rear-contact solar module at the event. The TAPI Rear Contact module, powered by n-type back-contact technology, achieves an efficiency of 24.6% and a power output of 665 W. It also eliminates front shading and performs efficiently in high temperatures. Commercial production is set to begin in the 2027 fiscal year.
Headquartered in Surat, Solex Energy currently operates 4 GW of photovoltaic module production capacity. Furthermore, under its Vision 2030 roadmap, the company plans to expand its solar module and solar cell manufacturing capacities to 10 GW each. Ultimately, this ambitious expansion will set new benchmarks for India’s rapidly developing solar industry.
