我们报道了使用改性单壁碳纳米管(SWNT)制备光伏器件。器件堆叠在掺氟氧化锡、电化学沉积的聚联噻吩层、与聚(3-辛基噻吩)混合的 SWNT 层以及蒸发的顶部金属触点、Ca/Al 或 Al 的顶部。 Ca/Al顶电极器件在15.5 W m–2的辐照度下实现了1.81 V的开路电压和1.48%的平均功率转换效率,光谱分布遵循AM1.5。 (© 2007 WILEY‐VCH Verlag GmbH & Co. KGaA,魏因海姆)
We report the preparation of photovoltaic devices using modified single wall carbon nanotubes, SWNTs. Devices are produced stacking on top of fluorine‐doped tin‐oxide, an electrochemically deposited polybithiophene layer, a layer of SWNT blended with poly(3‐octylthiophene) and an evaporated top metal contact, Ca/Al or Al. Ca/Al‐top‐electrode devices achieve open‐circuit voltages of 1.81 V and average power conversion efficiency of 1.48% at irradiance of 15.5 W m–2, spectrally distributed following AM1.5.
