Efficient photovoltaic-electrochemical water splitting for clean hydrogen

本项目旨在开发一种新型、低成本、高性能的单片光伏-电化学（PV-EC）清洁制氢装置。该装置定制并集成了低成本和高性能的薄膜和串联光伏电池，用于水分解，目标是实现高太阳能到氢的转换效率，达到20%。该项目将开发富含地球元素且稳定的催化剂，以取代贵金属催化剂，以及在PV-EC装置中用于电接触、馈通和催化剂集成的新型结构。这些创新提供了高性能和设备成本的潜力，比最近的世界纪录光电化学设备低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.
