使用p型半导体CuAlO 2，结合高效空穴注入染料和碘化物-三碘化物基电解质制备了染料敏化太阳能电池（DSC），展示了光阴极行为。与使用NiO的类似器件相比，观察到333 mV的改进的开路电压（VOC），这可以通过CuAlO 2价带能量来解释，其在真空尺度上低于NiO的价带能量。入射光子-电荷载流子效率响应证实了所观察到的光电流是由染料产生的。2011年，由美国光电仪器工程师学会（SPIE）
Dye-sensitized solar cells (DSCs) using the p-type semiconductor CuAlO2, in con- junction with a highly effective hole injecting dye and an iodide-triiodide-based electrolyte have been produced, demonstrating photocathodic behavior. An improved open-circuit volt- age (VOC) of 333 mV was observed, compared to analogous devices using NiO, which can be explained by the CuAlO2 valence-band energy, which is lower on the vacuum scale than that of NiO. Incident photon-to-charge-carrier efficiency response confirms that the observed photocurrent is generated by the dye. C 2011 Society of Photo-Optical Instrumentation Engineers (SPIE).
