Efficient photovoltaic-electrochemical water splitting for clean hydrogen

本项目旨在开发一种新型、低成本、高性能的单片式光伏电化学(PV-EC)清洁氢气生产装置。该设备定制并集成了低成本、高性能的薄膜和串联光伏来分解水，目的是实现接近20%的高太阳能到氢的转换效率。该项目将开发丰富和稳定的稀土催化剂，以取代贵金属基催化剂，以及用于PV-EC器件的电接触、馈通和催化剂集成的新架构。这些创新提供了高性能，潜在的器件成本比最近的世界纪录光电化学器件低2到3个数量级。

This project aims to develop a novel, low cost and high performance monolithic photovoltaic-electrochemical (PV-EC) device for clean hydrogen production. This device tailors and integrates low cost and high performance thin film and tandem photovoltaics for water splitting with the aim of achieving high solar to hydrogen conversion efficiency towards 20%. Earth abundant and stable catalysts will be developed in this project to replace noble based catalysts, as well as novel architectures for electrical contacting, feed-through and catalyst integration in PV-EC devices. These innovations offer high performance and the potential for device costs 2 to 3 orders of magnitude lower than recent world record photoelectrochemical devices.
