An asymmetrical squaraine dye (Py-3) with its two electron-donating aryl groups directly linked to the electron-withdrawing squaric acid core possesses an ideal bandgap of 1.33 eV, together with an intense and broad absorption band in the range 550-950 nm. Hence, the resulting solution-processed solar cells display an impressive Jsc of 12.03 mA cm(-2) and a PCE of 4.35%.
一种不对称方酸菁染料（Py-3），其两个供电子芳基直接连接到吸电子方酸核心上，具有1.33 eV的理想带隙，同时在550 - 950 nm范围内有强烈且宽泛的吸收带。因此，由此制备的溶液处理太阳能电池表现出令人印象深刻的12.03 mA cm⁻²的短路电流密度和4.35%的光电转换效率。
