Solex Energy Ltd has signed a Memorandum of Understanding (MoU) with ISC Konstanz, Germany, for R&D and technological collaboration in advanced solar cell manufacturing.
Under this strategic partnership, ISC Konstanz will extend comprehensive technological support to Solex for upgrading its upcoming TOPCon cell line and adopting next-generation rear-contact and c-Si tandem/perovskite solar technologies. The collaboration will also enable the establishment of Solex’s dedicated in-house R&D line, backed by ISC Konstanz’s patent portfolio, driving continuous innovation and high-efficiency solar manufacturing within India.
“This partnership marks a defining chapter in Solex’s journey toward technological excellence and global leadership. Under our Vision 2030, we are committed to transforming India into a hub of solar innovation with a targeted valuation of INR 1 lakh crore, a $1.5 billion investment, and 25,000 highly skilled team members driving that vision forward,” said Chetan Shah, chairman and managing director of Solex Energy Ltd.
“Our focus is not just on scaling capacity but on delivering unmatched value through efficiency, reliability, and performance. As we expand our global presence across India, Europe, and the U.S., we aim to build a future where clean, affordable energy empowers every home, business, and community. Together with ISC Konstanz, we are turning that vision into reality,” Shah added.
Radovan Kopeček, Head of Department Strategy and Education, ISC Konstanz, shared: “At ISC Konstanz, we have been steadily increasing photovoltaic efficiency while reducing costs since 2005. Our mission is to achieve research outcomes that benefit both industry and society. We set global standards, share expertise with partners and young talent worldwide, and remain driven by one ultimate goal, making clean solar energy accessible and affordable for all. Our partnership with Solex Energy brings us closer to realizing that vision and advancing a successful global energy transition.”
The event also saw the concept launch of a rear-contact solar module by Solex. Powered by n-type rear contact technology, TAPI Rear Contact module delivers up to 24.6% efficiency and 665 W power output with zero front shading and excellent temperature performance. The commercial production of TAPI Rear Contact is scheduled to commence by FY27.
Headquartered in Surat, Solex Energy has a 4 GW production capacity for PV modules. Under its Vision 2030, the company aims to establish 10 GW of solar module and 10 GW of solar cell manufacturing capacity, setting new benchmarks in Indian solar manufacturing.
