Impact of the architecture of dye sensitized solar cell-powered electrochromic devices on their photovoltaic performance and the ability to color change

•Architecture of DSC-powered photoelectrochromic devices was assessed.•WO3 on the counter-electrode allowed energy conversion efficiency of 6.9%.•WO3 on the working electrode demonstrated the best color contrast.•A proof of concept solar-powered pixelated device and smart window are demonstrated.
