Halocell Energy and Sofab Inks have announced breakthrough results from their ongoing collaboration to advance scalable perovskite photovoltaic (PV) modules.
Building on the strategic partnership announced in 2025, Halocell has successfully integrated Sofab Inks’ proprietary metal oxide nanoparticle inks as a charge transport layer in its module architecture. This integration aligns with Halocell’s roll-to-roll manufacturing approach, enabling continuous, low-cost production of thin, lightweight, and flexible perovskite PV modules.
Halocell specializes in perovskite PV technology optimized for a wide variety of lighting conditions. Some modules are designed for emerging applications including IoT devices, wireless sensors, and small indoor electronic. Other variants are being development for demanding sectors such as drones and space, where low weight and reliable performance in challenging environments are critical.
Under the collaboration, Sofab Inks supplies Halocell with advanced nanoparticle inks co-developed for the charge transport layer. Halocell continues to formulate and manufacture its own exclusive, proprietary perovskite inks — the core chemistry that underpins device performance.
Devices incorporating Sofab Inks’ metal oxide material have demonstrated exceptional durability under accelerated combined light and damp-heat testing (1,000 lux illumination, 85% relative humidity, 65°C):
- Modules with Sofab’s material maintained approximately 100% normalized efficiency after 1,300 hours.
- In contrast, control devices using commercially available charge transport layers degraded under the same conditions, dropping by approximately 20% normalized efficiency after 1,000 hours and further after 1,300 hours.
These results demonstrate the stability benefits of combining Halocell’s proprietary perovskite formulation with Sofab’s advanced metal oxide, alongside Halocell’s robust module architecture and encapsulation - addressing a key challenge for commercial perovskite deployment in humid or variable environments.
Halocell has now produced modules using the SoFab Inks and has begun shipping devices to selected partners for further evaluation and application development. The companies will continue their collaboration with a focus on scaling to larger-area modules and broader industrial use across a wider range of PV applications.
