Abstract

Abstract : Soft landing eliminates counter cations from Keggin polyoxometalate-based photocathodes, resulting in a ∼370% increase in maximum power output from a novel device that simultaneously harvests and stores solar energy. Abstract : The exceptional photochromic and redox properties of polyoxometalate anions, PW12 O40 3−, 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.
