Plasmonics boosts performance in polymer LEDs, solar cells

Facebook X LinkedIn Email
Using carbon-dot-supported silver nanoparticles to produce a surface plasmon resonance effect can boost the performance of both polymer LEDs (PLEDs) and polymer solar cells (PSCs) while keeping their structure simple. Most semiconducting optoelectronic devices – including solar cells, LEDs, photodiodes and semiconductor lasers – are based on inorganic materials. But these raw materials have limited availability and require complex processing, so these devices can be expensive to fabricate. Organic semiconductor devices are cheaper to make than inorganic ones, but further...Read full article

    plasmonics
    Plasmonics is a field of science and technology that focuses on the interaction between electromagnetic radiation and free electrons in a metal or semiconductor at the nanoscale. Specifically, plasmonics deals with the collective oscillations of these free electrons, known as surface plasmons, which can confine and manipulate light on the nanometer scale. Surface plasmons are formed when incident photons couple with the conduction electrons at the interface between a metal or semiconductor...
