表面等离子体-微腔激元对顶入射有机薄膜太阳能电池光吸收效率的增强
Plasmon-cavity Polaritons Enhance The Absorption Efficiency of Top-incident Organic Thin-film Solar Cells
摘要
Abstract
The absorption efficiency of top-incident organic thin-film solar cells ( TOSCs ) was im-proved by employing rectangle grating structure. The coupling mechanism between the hybridized surface plasmon polariatons and microcavity modes in ideal model of air/Ag1/active layer/Ag2/air ( IMIMI) structure was analyzed. By tuning the period of the grating and the thickness of the active layer, the resonance region of the hybridized surface plasmon polaritons and microcavity modes are matched with the intrinsic absorption range of the organic materials. Due to the electric field en-hancement effect of plasmon-cavity polaritons formed by the anticross-coupling between the micro-cavity modes and the surface plasmon polaritons, the absorption efficiency of the active layer is in-creased obviously, exhibits a increment of 19%.关键词
