    Abstract:

Applications: Relatively limited reserves of Indium and Gallium are expected to result into increased cost of CuInGaSe2 CIGS based solar cells.
Advantages: To address this challenge, 1. one could replace Indium and Gallium with Zinc and Tin that are relatively abundant, and also, 2. improve the CIGS material itself so that less amount of In and Ga Thinner CIGS film is required for the same efficiency solar cell. This project aims at pursuing both of these alternatives. Thin film solar cells will be fabricated using sputtering and CBD technique followed by high temperature treatment. Three other collaborators in this project are Dr. Nagesh Kini from Thermax Ltd., Pune. Prof. Dr. Roland Scheer from Martin Luther University Halle Wittenberg, Germany. Dr. Ralf Sorgenfrei, Manz CIGS Technology GmbH, Germany.

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.
