The exceptional photochromic and redox properties of polyoxometalate anions, PWO, have been exploited to develop an integrated photoelectrochemical energy storage cell for conversion and storage of solar energy. Elimination of strongly coordinating cations using benchtop ion soft landing leads to a ∼370% increase in the maximum power output of the device. Additionally, the photocathode displayed a pronounced color change from clear to blue upon irradiation, which warrants the potential application of the IPES cell in advanced smart windows and photochromic lenses.
多金属氧酸盐阴离子PWO卓越的光致变色和氧化还原特性已被用于开发一种用于太阳能转换和存储的集成光电化学储能电池。使用台式离子软着陆消除强配位阳离子可使该装置的最大功率输出提高约370%。此外,光阴极在光照下呈现出从透明到蓝色的明显颜色变化,这证明了IPES电池在先进智能窗户和光致变色镜片中的潜在应用。
