Next‐generation photovoltaic technologies such as dye‐sensitized solar cells, organic thin‐film photovoltaics and perovskite solar cells are promising to efficiently harvest ambient light energy. However, more and deeper understanding of their photovoltaic characteristics is essential to create new applications under room light illumination. In this study, for the first time, the difference in temperature coefficients and angular dependence of photovoltaic parameters for the large‐area devices are investigated systematically under the compact fluorescent lamp and light‐emitting diode light. These emerging photovoltaic devices, compared with the single crystalline silicon solar cells, not only have higher open‐circuit voltage (up to approximate 1 V) and better power conversion efficiency (in the range of 9.2% ~ 22.6%) but also exhibit less temperature dependent voltage and output power (< −0.6% °C−1), as well as broader angular response (over 75 degrees). The state‐of‐the‐art dye‐sensitized and organic thin‐film devices also show advantageously positive temperature coefficients of current, and the latter even has positive thermal dependence of fill factor. These features suggest the next‐generation photovoltaic devices are more favorable than the conventional crystalline silicon solar cells for real‐life indoor applications.

室内照明下下一代光伏电池的热和角度依赖性

染料敏化太阳能电池,有机薄膜光伏电池和钙钛矿太阳能电池等下一代光伏技术有望有效地收集环境光能。但是,对它们的光伏特性的更多,更深入的了解对于在室内光线照明下创建新应用至关重要。在本研究中,这是首次系统地研究了紧凑型荧光灯和发光二极管光下大面积器件的温度系数和光伏参数的角度依赖性。与单晶硅太阳能电池相比,这些新兴的光伏器件不仅具有更高的开路电压(高达约1 V)和更高的功率转换效率(在9.2%〜22范围内)。-1),以及更宽的角度响应(超过75度)。最先进的染料敏化和有机薄膜器件还显示出有利的电流正温度系数,而后者甚至对填充系数具有正热依赖性。这些特征表明,对于实际的室内应用而言,下一代光伏设备比传统的晶体硅太阳能电池更受青睐。
