Nanoporous Polymer Reflectors for Organic Solar Cells

Due to their high transparency, electrodes fabricated from conductive polymers are often implemented in semitransparent organic solar cells. Opaque cells usually employ metal back with reflectivity for best photon confinement the light-harvesting layer. Herein, a bilayer electrode comprising and nanofoamed poly(methyl methacrylate) (PMMA) is investigated, latter of which creates diffuse reflection incoming light. By tuning thickness PMMA layer, absorption transmission can be tailored opaque vastly transparent. its diffusive character, this versatile enhances light wavelength regimes lower coefficient. The particularly suited deployment frosted window applications.
