A sunflower field is often seen as an image of the active layer of dye‐sensitized solar cells (DSCs). Dye sensitizers that cover titanium oxide electrodes absorb sunlight. In this study, linear dyes containing boron β‐ketoiminate were synthesized and applied to DSCs. Their maximum incident photon‐to‐current conversion efficiencies reached 80% and were higher than those of DSCs using boron β‐diketonate dyes with a bent molecular structure. The photovoltaic characteristics revealed the effective process of light absorption–excitation–electron injection. More information can be found in the Full Paper by Katsuhiko Ono et al.

向日葵田通常被视为染料敏化太阳能电池（DSC）活性层的图像。覆盖氧化钛电极的染料敏化剂吸收阳光。在这项研究中，合成了含β-酮亚硼化硼的线性染料，并将其应用于DSC。它们的最大入射光子至电流转换效率达到80％，高于使用具有弯曲分子结构的β-二酮硼酸硼染料的DSC。光伏特性揭示了光吸收-激发-电子注入的有效过程。有关更多信息，请参见小野胜彦（Katsuhiko Ono）等人的论文全文。
