Abstract
Highly efficient large-area organic solar cells (OSCs) with power conversion efficiency up to 7.09%, and device area of 4 cm(2) are demonstrated on flexible substrates. A conductance- or thickness-gradient ultra-thin Ag-based transparent electrode is developed to better balance the light trapping and energy loss, owing to the inhomogeneous energy-loss density on the large OSC sheet.
