It is well known that the performance of Heterojunction with Intrinsic Thin Layer (HIT) solar cells depends critically on the quality of hetero-interfaces between the bulk crystalline silicon (c-Si) and intrinsic hydrogenated amorphous silicon (a-Si:H). There has been evolutionary improvement in the open circuit voltage (Voc) of HIT cells over the years primarily due to the improvements in the life...
Research on electronics applications such as light-emitting devices for flat-panel displays, transistors, sensors and even solid state lasers based on conducting polymers is presently under way and in some cases has reached the stage of prototype production. The mechanisms for charge injection and conduction in these materials are being studied, as are the physics of luminescence and its quenching...
We present photoluminescence and electroluminescence spectra of heterojunctions formed from poly(vinyl carbazole) (PVK) and poly(pyridyl vinylene phenylene vinylene) (PPyVPV). Bilayers of PVK and PPyVPV show a photoluminescence peak which cannot be assigned to either the PVK or the PPyVPV layer. Absorption spectra show that the additional feature results from an exciplex at the bilayer interface....
