Electrical and Optical Probing of Extremely Large Planar Polymer Light-Emitting Electrochemical Cells
… the original research on the electrical and optical scanning measurements on extremely large planar LECs is described. A fresh LEC film has, for the first time, been turned on to form a light-emitting p-n junction by biasing a pair of probes that form direct contacts with the LEC film. The …

Carrier transport properties measurements in wide bandgap materials
… obtain these transport properties. The two were optical beam induced current (OBIC) and electron beam induced current (EBIC) time of flight transient measurements. These techniques consist of measuring the current response to the drift and diffusion of generated electron-hole pair carriers …

CdTe solar cells: growth phenomena and device performance
… performance were evaluated with the aid of a optical beam induced current (OBIC) and external quantum efficiency (EQE) system built as part of this work and having the capacity to measure EQE or OBIC maps with a resolution of 12.5pm. The system was used to evaluate the photovoltaic response of …

Characterization Of Microstructural And Chemical Features In Cu-in-ga-se-s-based Thin-film Solar Cells
… efficiencies of these devices. Also, an optical equipment measuring photocurrents from a solar cell was developed for the identification of defect-prone regions of a thin-film solar cell. The focused ion beam (FIB) technique was used to prepare TEM samples. Bright-field TEM along with …
