The high molar absorption coefficient organic D-π-A dye C220 exhibits more than 6% certified electric power conversion efficiency at AM 1.5G solar irradiation (100 mW cm(-2)) in a solid-state dye-sensitized solar cell using 2,2',7,7'-tetrakis(N,N-dimethoxyphenylamine)-9,9'-spirobifluorene (spiro-MeOTAD) as the organic hole-transporting material. This contributes to a new record (6.08% by NREL) for this type of sensitized heterojunction photovoltaic device. Efficient charge generation is proved by incident photon-to-current conversion efficiency spectra. Transient photovoltage and photocurrent decay measurements showed that the enhanced performance achieved with C220 partially stems from the high charge collection efficiency over a wide potential range.
高摩尔消光系数有机 D-π-A 染料 C220 在使用 2,2',7,7'-四(N,N-二甲氧基苯基)胺-9,9'-螺二芴(spiro-MeOTAD)作为有机空穴传输材料的固态染料敏化太阳能电池中，在 AM 1.5G 太阳辐照（100 mW cm(-2))下的认证电功率转换效率超过 6%。这为这种类型的敏化异质结光伏器件创造了新的记录（NREL 的 6.08%）。通过入射光子电流转换效率光谱证明了有效的电荷产生。瞬态光电压和光电流衰减测量表明，C220 实现的性能提升部分源于在宽电位范围内的高电荷收集效率。
