Imprinted Electrodes for Enhanced Light Trapping in Solution Processed Solar Cells

A simple approach is demonstrated to combine a light trapping scheme and a conductive substrate for solution processed solar cells. By means of soft lithography, a new light‐trapping architecture can be integrated as the bottom electrode for emerging thin‐film solar‐cell technologies without added costs, fully compatible with low‐temperature processes, and yielding an enhancement in the photocurrent without altering the rest of the electrical performance of the device.
