摘要

小分子顶入射有机光伏(TIOPV)模块的效率显著提高，通过利用具有多次反射的光收集设计来有效地耗尽入射光子。在这种光收集设计中，来自一个OPV的反射是另一个OPV的入射光。通过调整夹在反射银阳极和半透明银阴极之间的有源层的厚度，对单个TIOPV的内部光场分布和外部反射谱进行了重新排列。外部反射光子能量可以被下一个TIOPV器件部分吸收，产生转换光电流。经过一系列反射后，原始入射光子能量被耗尽，转化为光电流。

Efficiency enhancement of top-incident organic photovoltaics using multiple reflection design for exhausting incident photons

A significant efficiency enhancement of the small-molecule top-incident organic photovoltaic (TIOPV) module is demonstrated by utilizing a light harvesting design with multiple reflections to effectively exhaust the incident photons. In this design, the reflection from one OPV is the incident light for another OPV in this light harvesting design. Adjusting the thickness of active layers sandwiched in between reflective Ag anode and semitransparent Ag cathode, the internal optical filed distribution and external reflection spectrum have been rearranged for a single TIOPV. The external reflection photon energy could be partially absorbed by the next TIOPV device to generate the conversion photocurrent. The original incident photon energy could be exhausted after a sequence of reflections, converting to photocurrent.
