Journal: | Nano Energy | Abstract: | Building-integrated solar cells not only generate electricity but also impact the envelope thermal characteristics, thus changing the micro-climate of buildings. Therefore, the collective effects of energy conservation and generation on buildings should be considered in one design. In this work, a smart photovoltaic window foil with near-infrared (NIR) modulation and low long-wavelength IR emissivity has been fabricated by combining organic perovskite and inorganic tungsten doped vanadium dioxide nanoparticles (W-VO2 NPs). The W-VO2 offers solar modulation and promotes extraction and transport of photogenerated charges, giving peak power conversion efficiency of 15.4% at 25 ℃ and 16.1% at 45 ℃ and average visible transmission of 25.5%, comparable to the best reported semitransparent perovskite solar cell with an additional favorable NIR modulation of 10.7%. This new strategy to integrate energy-saving functionality into photovoltaic foil initiates a new design rule for smart window development. | URI: | https://hdl.handle.net/10356/152956 | ISSN: | 2211-2855 | DOI: | 10.1016/j.nanoen.2021.106632 | DOI (Related Dataset): | 10.21979/N9/J57WGK | Rights: | © 2021 Elsevier Ltd.
