Kalyon PV and the Institute for Solar Energy Research Hamelin (ISFH) are excited to announce a pioneering collaboration focused on the development and optimization of innovative POLO IBC (Polycrystalline silicon on Oxide Interdigitated Back Contact) cell technology. This partnership aims to push the boundaries of solar cell efficiency and production capabilities.
Advancements in POLO IBC Cell Technology
The ISFH has successfully developed a POLO IBC cell with an impressive efficiency potential of 25%. This breakthrough leverages a process based on industrial bifacial PERC (Passivated Emitter Rear Cell) cells, utilizing a unique shadow mask for local polycrystalline silicon (POLO) deposition. This innovative design is at the heart of the POLO IBC technology and is developed and licensed by ISFH.
Collaborative Efforts and Future Enhancements
Kalyon PV will have the opportunity to enhance this cutting-edge cell technology through its advanced production lines as part of its future production plans. This strategic collaboration will enable Kalyon PV to integrate ISFH's POLO IBC technology, significantly elevating their production capabilities and efficiency standards.
IBC4EU Project Success
Within the context of the IBC4EU Project, Kalyon PV's Ga-doped wafers have been successfully tested for the POLO-IBC cells, achieving a remarkable efficiency of 23.4% and an iVoc (implied-open circuit voltage) of 740 mV. These results underscore the promising potential of combining Kalyon PV's materials with ISFH's technological advancements.
Knowledge Transfer and Innovation
A core component of this collaboration is the transfer of ISFH's specialized know-how to Kalyon PV. Through this partnership, Kalyon PV will gain critical insights and capabilities to evaluate and apply POLO IBC technology in their future production processes. This knowledge transfer aims to catalyze significant advancements in the solar energy sector.
"We are thrilled to join forces with ISFH, one of the significant solar technology research institutes in Germany," said Ersan Tüfekçi, CEO of Kalyon PV. "This collaboration aligns with our vision of pioneering high-efficiency solar cells and underscores our commitment to sustainable energy solutions."
ISFH's PV department leader Dr. Thorsten Dullweber added, "Partnering with Kalyon PV allows us to expand the impact of our POLO IBC technology. Together, we can drive forward the efficiency and production of solar cells, contributing to the global renewable energy landscape."
