제목 Fabrication and characterization of electro-photonic performance of nanopatterned organic optoelectronics
초록 For high efficiency of photovoltaic cell, it is desirable to make a thin photoactive layer, with enhanced absorption. One way to satisfy these requirements is to use a light trapping scheme, which employs a thin cell geometry where the incident light makes multiple passes through the photoactive organic layer. We demonstrate light trapping scheme using pattern replication in non-wetting templates (PRINT). This light trapping scheme is fabricated from patterning photoactive layer with features on a 200 nm scale. It can be replicated with PRINT and well reproduced several times with the same template. It can offer a solution to the exciton diffusion length/ optical absorption length mismatch with the reduced series resistance at the same time. Nano-patterns can also enhance performance of other optoelectronic devices including organic laser
