<scp>Hot‐electron emission‐driven</scp> energy recycling in transparent plasmonic electrode for organic solar cells

Plasmonic metal electrodes with subwavelength nanostructures are promising for enhancing light harvesting in photovoltaics. However, the nonradiative damping of surface plasmon polaritons (SPPs) during coupling sunlight results conversion excited hot-electrons to heat, which limits absorption and generation photocurrent. Herein, an energy recycling strategy driven by hot-electron emission SPP trapped plasmonic is proposed. A transparent silver-based electrode (A-PME) a periodic hexagonal nanopore array constructed, combined luminescent organic emitter radiative recombination injected hot-electrons. Owing suppressed loss via broadband emission, A-PME achieves optimized optical transmission average transmittance over 80% from 380 1200 nm. Moreover, indium-tin-oxide-free solar cells yield enhanced power efficiency 16.1%.
