Photovoltaic devices that switch color depending on illumination conditions may find application in future smart window applications. Here a photochromic diarylethene molecule is used as sensitizer in a ternary bulk heterojunction blend, employing poly(4-butylphenyldiphenylamine) (poly-TPD) and [6,6]-phenyl-C-butyric acid methyl ester (PCBM) for the transport of holes and electrons, respectively. Sandwiched between two electrodes, the blend creates a photochromic photovoltaic device that changes color, light absorption, and photon-to-electron conversion efficiency in the visible spectral range after having been illuminated with UV light.

能够根据光照条件改变颜色的光伏器件可能会在未来的智能窗户应用中得到应用。在这里，一种光致变色二芳基乙烯分子被用作三元体异质结混合物中的敏化剂，分别采用聚（4-丁基苯基二苯胺）（聚-TPD）和[6,6]-苯基-C-丁酸甲酯（PCBM）来传输空穴和电子。夹在两个电极之间，这种混合物形成了一种光致变色光伏器件，在用紫外光照射后，它会在可见光谱范围内改变颜色、光吸收和光子到电子的转换效率。
