Role of TCO layer on the performance of a-Si:H solar cells

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

It is known that the performances of the a-Si.H solar celIs are affected by theTransparent Conductive Oxide (TCO) fil~ deposited on the glass substrate [1]. Here, wepropose to study the role of the TCO structure on the main characteristics of amorph~ussilicon solar cells.As references, we choose two different ITOs deposited by Thermal ReactiveEvaporation, showing different surface morphologies (type A and type B).These differentsurface morphologies can be obtained by changing some deposition parameters, namely thedeposition rate and the alloy concentration. Besides that, as the ITO layer is reduced ",:henexposed to a hydrogen plasma, a protective thin SiO layer is also used to prev.ent.filrnsreduction. Preliminary studies concerning the role of the SiO layer showed a sígníficantincrease (up to 17%)on the solar celIsefficiency.AlI these data will be presented towards theimplementationof the final solar cell efficiencyand stability.
