2016年2月15日 · An inverted bulk heterojunction perovskite–PCBM solar cell with a high fill factor of 0.82 and a power conversion efficiency of up to 16.0% was fabricated by a low-temperature two-step solution...

2011年12月1日 · ZnTPP:PCBM bulk heterojunction (BHJ) solar cells fabricated and characterized for optical and electronic properties. ZnTPP (donor) and PCBM (acceptor) ratios in the BHJ solar cells varied to find ratio for best performance. ZnTPP:PCBM BHJ solar cells showed the best efficiency (0.21%) at ZnTPP to PCBM weight ratio of 1:9. Absorption spectra of ...

We provide firm evidence of the nanoscale organization of the P3HT polymer and of the P3HT:PCBM stoichiometric mixtures at the surface–air interface of the BHJ architecture. Our study shows the characteristic periodicity of the regioregular P3HT identified in the nanoscale domain areas with submolecular resolution.

2024年8月6日 · The improved optoelectronic performance of BHJ PD is due to increased interfacial area, higher electron extraction and a decrease in traps and defects. The analysis of dark current–voltage curves reveals a significant reduction in charge recombination for BHJ devices, supporting the elimination of traps and defects by the inclusion of PCBM.

2020年7月1日 · On top of HTL, is deposited a BHJ layer (basic region for light absorption) formed by a blend of n-type and p-type material (P3HT:PCBM). This layer is followed by an electron transport layer (ETL) often formed by a conductor oxide such as Zin Oxide (ZnO) or Titanium Oxide (TiO2) [7] and finally the cathode.

在有机供体和受体界面处的能级对准是确定有机太阳能电池中光伏性能的关键，但是直接探测这种能级对准仍然具有挑战性，尤其是对于溶液处理的体异质结（BHJ）薄膜。在这里，我们报告了系统研究，目的是探讨五种常用聚合物中不同方法的能级比对： [6,6]-苯基-C 71-丁酸甲酯（PCBM）BHJ系统。我们 ...

2019年4月30日 · Bilayer and bulk heterojunction (BHJ) organic solar cells were simulated and studied in five structures by one-dimensional AMPS software. In bilayer structures,

2009年10月27日 · In this paper, we show that the BHJ geometry is not necessary for high efficiency, and that all-solution-processed P3HT/PCBM bilayer solar cells can be nearly as efficient as BHJ solar cells fabricated from the same materials.

2016年3月16日 · The effect of post deposition annealing on the electron transport as well as photovoltaic properties of P3HT:PCBM bulk heterojunction (BHJ) thin films was investigated.

基于聚合物和甲基富勒烯（ [60] PCBM或 [70] PCBM）的本体异质结（BHJ）的有机太阳能电池展现出复杂的形态，可控制其光伏和机械顺应性（鲁棒性，柔韧性和可拉伸性）。
