Multi-functional films with tunable electrical and optical properties are key to developing efficient and visually attractive silicon solar panels. Yet, a single-component material has not been able to address the challenge. Researchers now have found a means to blend multiple polymers and inorganic components in nanocomposite films. The optical and electrical properties of the nanocomposite films can be easily tailored to meet the requirement of rendering silicon solar cells of any designer color whilst maintaining efficient power conversion efficiencies. Cells with vivid colors offer the promise of the otherwise dull silicon solar panels as decorative structural materials.
