Silicon wafers play an indispensable role in microfluidic chip manufacturing and can be used to prepare SU8 molds, silicon molds, and silicon runner chips. SU-8 Mold Silicon wafers are widely used in SU-8 mold preparation. PMMA/PC/COC ...
In this study, we demonstrate an improvement in photovoltaic properties in inverted OSCs by introducing the patterned structures in the active layer (PTB7:PC70BM) using a nano-imprinting technique with a PDMS stamp. By adjusting pressure of imprinting the active layer, the imprinted OSCs were ...
The basic process consists of imprinting a pattern through a master stamp in a liquid polymer thin layer by applying a certain pressure, followed by the polymeric curing process (by heating or UV curing), obtaining an impression of the stamp inside the polymer. This technique allows the ...
