Efficiency Enhancement of Organic Solar Cells with Process-Optimized Silver Nanoprisms

Article Preview

Abstract:

We fabricated silver nanoprisms (AgNPs) on ITO by immersing ITO substrates in AgNPs solution for a series of immersion times. The amount of adsorbed AgNPs increased with immersion time. The AgNPs showed plasmonic absorption in the range of 400 – 600 nm and were used in organic solar cells (OSCs). The device performance was the best when the immersion time was 30 min, corresponding to AgNPs coverage of 68%. Under this condition, the device showed short-circuit current density (JSC) of 10.10 mA cm-2 (18% improved), and power conversion efficiency (PCE) of 3.88% (23% improved).
