摘要:

High-performance single-junction PSCs with an efficiency over 10% have been demonstrated by implementing the DAN patterning for broadband self-enhanced light absorption with optimum charge extraction. The light manipulation approach used here is advantageous to manufacturing compatibility for large-area, flexible, and low-cost electronic devices, and highly capable of light trapping with broad spectral response. Compared with the reference device with a flat structure, enhanced light harvesting in nanostructured PSCs is achieved, yielding an 18% increase in photocurrent and an improved PCE of 10.1% without sacrificing the charge transport properties. By using experimental photocurrent measurements in combination with optical modeling, the dramatic performance enhancement is clarified as the self-enhanced absorption due to collective excitation and hybridization of several factors, including the pattern-induced anti-reflection, light scattering as well as surface plasmonic resonance, together with a minimized recombination probability. We anticipate that our findings will promote the development of high-efficiency PSCs with new device structures.
