Enhanced solar-cell efficiency in bulk-heterojunction polymer systems obtained by nanoimprinting with commercially available AAO membrane filters

Enhanced solar-cell efficiency in bulk-heterojunction polymer systems obtained by nanoimprinting with commercially available AAO membrane filters are discussed. The study revealed that the simple method can he employed to enhance the performance of polymerized photovoltaic cells, where the process involves the use of a commercially available AAO membrane filter to control the morphology of the surface of the active layer. The study has developed a new procedure for the construction of polymer-based, bulk heterojunction solar cells that have considerably improved PCE. The sequence used to prepare the solar cell begins with cleaning a patterned ITO glass sequentially with a detergent solution, acetone, and isopropyl alcohol, followed by drying in a vacuum oven. The type of morphological control applied to the surface can increase light scattering in this device and lead to a greater utilization of incident light.
