Abstract
Thermochromic smart windows (TSWs) exist passive regulation for building energy conservation, which are challenging to be artificially manipulated. The electrothermal stratagem has been explored for introducing the “active control” function. However, it is limited by the excess electricity consumption. Here, we fabricate a TSW with electricity-efficient tunable functions by combining transparent photothermal and electrothermal technologies. The “active control” function is escorted by a transparent electrode with electrical conductivity and photothermal efficiency from layer-by-layer (LBL) assembled silver nanowires and MXene nanosheets. It shows high transparent sunlight conversion to lower the inherent temperature threshold for thermochromism and retrenches the electricity consumption. Under the synergistic effect of photothermal and electrothermal processes, the TSWs show remarkable solar modulation (ΔTsol = 61.8%) during both summer and winter. The LBL-assembly technique is simple to manipulate, which provides an energetic paradigm for the commercial applications of TSWs while enabling superb annual building energy conservation.
期刊介绍:
ACS Materials Letters is a journal that publishes high-quality and urgent papers at the forefront of fundamental and applied research in the field of materials science. It aims to bridge the gap between materials and other disciplines such as chemistry, engineering, and biology. The journal encourages multidisciplinary and innovative research that addresses global challenges. Papers submitted to ACS Materials Letters should clearly demonstrate the need for rapid disclosure of key results. The journal is interested in various areas including the design, synthesis, characterization, and evaluation of emerging materials, understanding the relationships between structure, property, and performance, as well as developing materials for applications in energy, environment, biomedical, electronics, and catalysis. The journal has a 2-year impact factor of 11.4 and is dedicated to publishing transformative materials research with fast processing times. The editors and staff of ACS Materials Letters actively participate in major scientific conferences and engage closely with readers and authors. The journal also maintains an active presence on social media to provide authors with greater visibility.
