Novel near-infrared (NIR)-sensitizing (up to 800 nm) simple asymmetric squaraine dyes (Sq 31 and Sq 33) carrying indoline moieties that did not require the introduction of any linker groups were developed. DSSCs fabricated with Sq 33 exhibited remarkable characteristics in the long-wavelength visible and NIR region (up to 800 nm), such as a conversion efficiency of 3.75% (AM 1.5G) with an incident photon-to-current conversion efficiency of 63% (650 nm), a short-circuit photocurrent density of 13.64 mA, an open-circuit photovoltage of 0.48, and a fill factor of 0.57.
开发了新型近红外（NIR）敏化（高达 800nm）的不对称方酸染料（Sq 31 和 Sq 33），它们带有吲哚啉基团，不需要引入任何连接基团。使用 Sq 33 制造的 DSSC 在长波长可见光和 NIR 区域（高达 800nm）表现出显著的特性，例如转换效率为 3.75%（AM 1.5G），入射光子到电流的转换效率为 63%（650nm），短路光电流密度为 13.64mA，开路光电压为 0.48，填充因子为 0.57。
