Abstract

A solution-processed self-powered polymer electrochromic/photovoltaic (EC/PV) device is realized by vertically integrating two transparent PV cells with an ECD. The EC/PV cell is a net energy positive dual functional device, which can be reversibly switched between transparent and colored states by PV cells for regulating incoming sunlight through windows. The two PV cells can individually, or in pairs, generate electricity.

Keywords: dual function device; energy efficient buildings; solar-powered electrochromic window; solution-processed conjugated polymers; tandem solar cells; transparent organic photovoltaic cells.
