The article shows the comprehensive results of the experiments, conducted in order to select the appropriate metal layers, for back absorber contacts, to apply in flexible, thin-film photovoltaic cells based on cadmium telluride. Preliminary selection of investigated materials was made on the basis of general knowledge and physical data. Deposition techniques, as well as layer parameters, were adjusted to the specific flexible solar cell's needs. Selected metal layers were deposited either by physical vapour deposition (PVD) or screen-printing method (SP) and tested in terms of their flexibility, thermal resistance, as well as adhesion to CdTe layer. Practical verification of selected configurations is proved by the complete construction of the device.
We carry out Monte Carlo simulations of electron transport in 4H-silicon carbide (4H-SiC) based on the numerically calculated density of states (DOS) to obtain the electron mobility at low electric fields. From the results, it can be concluded that a correct calculation of the DOS requires a very dense wavevector k-mesh when low electron kinetic energies are considered. The crucial issue is the numerical efficiency of the DOS calculation. We investigate the scaling efficiency when different numbers of cores are used.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
