A technique for improving the spatial resolution of the magnitude of photocurrent measured for photoactive materials in general and solar cells and panels, in particular, using light beam induced photocurrent (LBIC) scanning technique. The method involves a non-sequential positioning of the focused light beam from a directed light source like LASER or light emitting diode, over the photoactive region of solar cell and panels for minimizing the spatial correlation in photocurrent magnitude between the successive data points. The temporal correlation can be mitigated by utilizing a dynamic scanning at selected points which will represent the time-varying decay in photocurrent response of the photoactive material.

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.
