Experimental evaluation of ITO, AZO, TiO2 and CNT compounds as transparent conductive layers for flexible PV structures

This paper presents a comparison of optical, electrical and mechanical properties of various types transparent conductive layers (TCLs). Metal oxides such as indium tin oxide (ITO), aluminum doped zinc oxide (ZnO:Al) and titanium dioxide (TiO
2
), as well as carbon nanotube composites were utilized for layers manufacturing. For each TCL, different production technology was applied. All examined materials were deposited on flexible transparent polymer substrates. Obtained results were analyzed in order to verify suitability of investigated compounds for application in flexible photovoltaic structures as emitter electrodes. Presented paper is a part of the project of a new elastic PV cell construction.
