Abstract

In this paper, a natural dye extracted from Beta vulgaris was used as photosensitizer for fabricating dye sensitized solar cells. The effect of conventional annealing and microwave annealing on the surface morphology of titanium dioxide layer and on the performance of dye sensitized solar cells were studied. The photovoltaic parameters: short circuit current (Isc), maximum current (Imax), open circuit voltage (Voc), maximum voltage (Vmax), fill factor and efficiency (η) of dye sensitized solar cells are reported. The efficiency of conventionally annealed dye sensitized solar cells was found to be ∼1.20 and the efficiency of microwave annealed dye sensitized solar cells were about ∼0.29. However, a maximum voltage of 0.26 V was obtained in dye sensitized solar cells annealed under microwave radiation for 10 min.

微波退火对以甜菜为天然染料的染料敏化太阳能电池性能的影响

摘要

在本文中,从甜菜中提取的一种天然染料用作制备染料敏化太阳能电池的光敏剂。研究了常规退火和微波退火对二氧化钛层表面形貌和染料敏化太阳能电池性能的影响。光伏参数:短路电流(I sc)、最大电流(I max)、开路电压(V oc)、最大电压(V max)、填充因子和效率(η) 的染料敏化太阳能电池。发现常规退火染料敏化太阳能电池的效率约为 1.20,微波退火染料敏化太阳能电池的效率约为 0.29。然而,在微波辐射下退火 10 分钟的染料敏化太阳能电池中获得的最大电压为 0.26 V。
