Plasmonic metallic nanoparticles (NPs) have recently been identified as a breakthrough
route for enhancing the efficiency of organic photovoltaic (OPV) devices. The present review …

Recent advances in molecular organic photovoltaics (OPVs) have shown 10% power
conversion efficiency (PCE) for single‐junction cells, which put them in direct competition …

Metallic nanoparticles such as silver and gold show localized surface plasmon resonances
(LSPRs), which are associated with near-field enhancement effects in the vicinity of …

Two of the recent major research topics in optoelectronic devices are discussed: the
development of new organic materials (both molecular and polymeric) for the active layer of …

A major issue in organic solar cells is the poor mobility and recombination of the
photogenerated charge carriers. The active layer has to be kept thin to facilitate charge …

Colorimetric sensors usually suffer due to errors from variation in light source intensity, the
type of light source, the Bayer filter algorithm, and the sensitivity of the camera to incoming …

Organic photovoltaic (OPV) devices, which can directly convert absorbed sunlight to
electricity, are stacked thin films of tens to hundreds of nanometers. They have emerged as a …

Organic photovoltaic (OPV) cells have the potential to make a significant contribution to the
increasing energy needs of the future. In this book, 15 chapters written by selected experts …

We numerically study complex dual-interface grating systems to enhance absorption
