Organic solar cells (OSCs) require a bulk heterojunction of a donor and an acceptor for efficient charge generation, whereas other types of solar cells normally use the p‐i‐n device structure. Herein, a comparative investigation of the p‐i‐n‐structured OSCs is conducted based on single‐donor‐component BTID‐0F and the bulkheterojuction OSCs with different donor:acceptor blend ratios using BTID‐0F as the donor and PC71BM as the acceptor. The highest power conversion efficiency (PCE) of 1.61% is obtained for single‐donor‐based OSCs. The impact of PC71BM weight ratio in BTID‐0F:PC71BM‐based OSCs upon blend morphology, material energetics, photogenerated charge dynamic process, and photovoltaic device performance is investigated, and the highest PCE reaches 8.47%. Results indicate that even when the acceptor sites are highly diluted and the acceptor phase is discontinuous, electron transport can occur with a reasonable electron mobility. The PCE of 1.61% is the highest PCE reported for p‐i‐n structure OSCs based on a single‐donor component, which is helpful to understand the mechanism of charge generation in organic materials and thus obtainhigh‐efficient OSCs using the p‐i‐n structure.

基于单施主成分的p-i-n结构有机太阳能电池中的高效电荷产生

有机太阳能电池(OSC)需要供体和受体的整体异质结才能有效地产生电荷,而其他类型的太阳能电池通常使用p-i-n器件结构。在此,基于单供体组分BTID-0F和具有不同供体:受体混合比的体异质结OSC进行了对p-i-n结构OSC的比较研究,使用BTID-0F作为供体,PC 71 BM作为接受者。对于基于单施主的OSC,最高的功率转换效率(PCE)为1.61%。PC 71 BM重量比对BTID-0F:PC 71的影响基于混合形态,材料能量,光生电荷动态过程和光伏器件性能的基于BM的OSC进行了研究,最高PCE达到8.47%。结果表明,即使当受体位置被高度稀释并且受体相不连续时,也可以以合理的电子迁移率发生电子传输。PCi为1.61%,是基于单施主组分的p-i-n结构OSC的最高PCE,这有助于了解有机材料中电荷产生的机理,从而使用p-i获得高效的OSC -n结构。
