SunHydrogen, a US-based company, has achieved a record efficiency with its 1200cm2 hydrogen module in Japan. The module reached a 9% solar-to-hydrogen efficiency, which is the highest reported for a module of this size. Tests at the University of Tokyo showcased the scalability of SunHydrogen's technology while maintaining efficiency levels close to what was achieved with smaller 100cm² modules. The company's Chief Technology Officer, Dr. Syed Mubeen, expressed the goal of refining the design further to exceed 10% efficiency. CEO Tim Young highlighted the successful maintenance of high efficiency during the scale-up process. SunHydrogen also collaborated with Honda R&D for real-world testing of their smaller 100cm² modules, with plans to test the 1200cm2 modules under on-sun conditions using a similar setup. The company will leverage data from these tests to enhance their modular design. SunHydrogen's modules, developed in partnership with CTF Solar, aim to enhance photovoltaic elements for efficient hydrogen production. The developments signify a positive step towards increasing efficiency and real-world application of hydrogen technology.
