Abstract:
Thinfilm solar cells based on Cu2ZnSnS4(CZTS) absorber material suffers from performance issues arising due tothe presence of a non-optimal back contact barrier, low carrier lifetime, acceptor/donor point defects in bulk,interface defects at the absorber-buffer junction and grain boundaries within the absorber. We perform com-prehensive simulations enumerating the impact of these performance limiting factors on CZTS solar cells. Thesesimulations capture the experimentally observed anomalies in current-voltage (I–V) characteristics and the open-circuit voltage (VOC) pinning in CZTS solar cells. These cause-effect relationships as elaborated in thefindings areexpected to be of great interest to the experimentalists working in thisfield.

THE VISION
THE MISSION
ABOUT I-STEM
It has always been the basic tenet of the Government of India, in generously funding R&D efforts at academic institutions over the years, that facilities established through such support be made available to those needing them and qualified to make use of them for their own research work

However, this was never easy or straightforward for, among other reasons, there was no ready source of information of what facility was available and where. Thanks to the Web, it is much easier today to have a national and regional “inventory of resources”, so as to match users with the resources they need, and to do all this in an efficient and transparent manner.

This can lead to a leap in R&D productivity and greatly enhance the effectiveness of public investment. This is the motivation behind I-STEM.
