WebJan 13, 2014 · The formation of the Schottky barrier height (SBH) is a complex problem because of the dependence of the SBH on the atomic structure of the metal-semiconductor (MS) interface. Existing models of the SBH are too simple to realistically treat the chemistry exhibited at MS interfaces. This article points out, through examination of available ...
Webcontacts and for the extraction of fundamental parameters such as the Schottky barrier (SB) height and the contact resistance. To study the I-V characteristic of two terminal devices with SBs, the classic equation of the Schottky diode is often used. This equation considers that charge carriers cross an energy barrier by thermionic emission. WebWe validate the HJ hypothesis using an extensive set of experiments on a high- efficiency SHJ solar cell. Our work establishes Suns-Voc as a powerful characterization tool for extracting the cell parameters that limit efficiency in heterojunction devices.
