    Sammanfattning : Lead-free halide double perovskites (HDPs, A2BIBIIIX6) with attractive optical and electronic features are regarded as one of the most promising alternatives to overcome the toxicity and stability issues of lead halide perovskites. They provide a wide range of possible combinations and rich substitutional chemistry with interesting properties for various optoelectronic devices. LÄS MER

  2. 2. VO2-based Thermochromic and Nanothermochromic Materials for Energy-Efficient Windows : Computational and Experimental Studies

    Författare :Shuyi Li; Claes-Göran Granqvist; Gunnar Niklasson; Ivan Parkin; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; VO2; thermochromism; nanothermochromics; energy efficient windows; optical modeling; effective medium theory; thin film characterization; doping;

    Sammanfattning : VO2-based films are thermochromic and exhibit high or low infrared transmittance when the temperature is below or above a critical temperature. The thermochromic switching is passive and reversible, and therefore VO2 based films are promising for energy-efficient window appli­cations. LÄS MER
