Three Fraunhofer institutes in Germany have collaborated on the Neo-PEC joint research project, developing a pioneering tandem PEC module for direct hydrogen production. This innovative module, presented in June, offers a flexible and scalable solution for generating hydrogen using solar energy. By utilizing semiconducting materials on glass, the module efficiently splits water into hydrogen and oxygen. The addition of photovoltaic elements enhances the process, increasing efficiency and overall hydrogen yield. The researchers have optimized the semiconductor materials through gentle coating processes, resulting in high-purity hydrogen production. With the ability to generate around 30 kg of hydrogen with 100 square meters of module area, the module has significant potential for various applications, including powering hydrogen cars for long distances. The module's design allows for easy scalability by connecting multiple units, providing a practical and efficient solution for hydrogen production. The project involves field tests conducted by the Fraunhofer Institute for Surface Engineering and Thin Films IST and the Fraunhofer Center for Silicon Photovoltaics CSP, with plans for further collaboration and industry involvement in the future.
