有机敏化剂包括给体、电子传导和锚定基团，被设计和开发用于染料敏化太阳能电池应用。一种采用3-作为空穴传输材料的（5 ′-{4-[双-（4-己氧基-苯基）-氨基]-苯基}-[2，2 ′]双噻吩-5-基）-2-氰基-丙烯酸染料螺-OMeCl 2显示出9.64 mA/cm（2）的短路光电流密度、798 mV的开路电压和0.57的填充因子，对应于在标准AM 1.5太阳光下4.4%的总转换效率。光诱导吸收光谱探测了从染料到螺环-OMe的有效空穴转移。
Organic sensitizers comprising of donor, electron-conducting, and anchoring groups are designed and developed for dye-sensitized solar cell applications. A solar cell employing 3-(5'-{4-[bis-(4-hexyloxy-phenyl)-amino]-phenyl}-[2,2']bithiophenyl-5-yl)-2-cyano-acrylic acid dye spiro-OMeTAD as a hole-transporting material exhibits a short circuit photocurrent density of 9.64 mA/cm(2), an open-circuit voltage of 798 mV, and a fill factor of 0.57, corresponding to an overall conversion efficiency of 4.4% at standard AM 1.5 sunlight. Photoinduced absorption spectroscopy probes an efficient hole-transfer from dyes to the spiro-OMeTAD.
