Abstract
Over the past several decades, research in organic semiconductors has progressed steadily to the point that commercial applications have been realized in areas such as organic light emitting diodes (OLEDs) for solid state lighting and displays, as well as organic field effect transistors (OFETs) for RFIDs, e-paper and flexible electronics. The use of organic semiconductors for photo-voltaics (PV) has also seen tremendous progress over the past decade with power conversion efficiencies that have risen from 1% to above 10% as reported recently. The urgency for developing low-cost, high-efficiency renewable energy sources is very pressing since worldwide demand for energy is expected to triple by the end of the century. Organic PV provides advantages in its very low-cost manufacturing processes that utilize room temperature techniques, unlike crystalline Si and other inorganic PV technologies that are not cost-effective. Other advantages of OPV includes the use of environmentally friendly materials, and compatibility with roll-toroll processing for the realization of solar cells in a flexible and conformable platform.
