Title: | Perovskite photovoltachromic supercapacitor with all transparent electrodes | Authors: | Zhou, F Ren, Z Zhao, Y Shen, X Wang, A Li, YY Surya, C Chai, Y |
Issue Date: | 28-Jun-2016 | Source: | ACS nano, 28 June 2016, v. 10, no. 6, p. 5900-5908 | Abstract: | Photovoltachromic cells (PVCCs) are of great interest for the self-powered smart windows of architectures and vehicles, which require widely tunable transmittance and automatic color change under photostimuli. Organolead halide perovskite possesses high light absorption coefficient and enables thin and semitransparent photovoltaic device. In this work, we demonstrate co-anode and co-cathode photovoltachromic supercapacitors (PVCSs) by vertically integrating a perovskite solar cell (PSC) with MoO3/Au/MoO3 transparent electrode and electrochromic supercapacitor. The PVCSs provide a seamless integration of energy harvesting/storage device, automatic and wide color tunability, and enhanced photostability of PSCs. Compared with conventional PVCC, the counter electrodes of our PVCSs provide sufficient balancing charge, eliminate the necessity of reverse bias voltage for bleaching the device, and realize reasonable in situ energy storage. The color states of PVCSs not only indicate the amount of energy stored and energy consumed in real time, but also enhance the photostability of photovoltaic component by preventing its long-time photoexposure under fully charged state of PVCSs. This work designs PVCS devices for multifunctional smart window applications commonly made of glass. | Keywords: | Electrochromic Energy storage Perovskite solar cell Photostability Photovoltachromic supercapacitor (PVCS) |
