Abstract
The confinement property of polysilicon contacts, leading to storage of minority carriers, has been studied using the photoconductivity technique. Steady-state and transient optical measurement show a considerable increase of stored carriers by these contacts. A model has been developed that allows the extraction of contact parameters
