Researchers at Arizona State University have developed a new method that will increase the efficiency and absorption of photosensors through the use of plasmonic layers of interconnected metal nanoparticles disposed on a substrate. Combining this with dendritic electrode growth, allows for tunable plasmonic structures that can have enhanced light capturing ability across a wide spectrum spanning the UV and visible light range. This greatly increases the efficiency of solar cells and optical sensors. For example, it is predicted that a photovoltaic layer could be thinned as much as 100x while maintaining efficiency using plasmonic techniques.
