Long description:

Thin film solar cell has the potential to be an important contributor to the global energy demand by mid 21st century. Thin film solar cell which has achieved the laboratory efficiency close to 20%, are highly attractive because there band gap is near the optimal value, their polycrystallinity is not significantly detrimental to their performance and the broad choice of heterojunction partners available allows additional degrees of freedom for optimizing their performance. This research is intended to improve the efficiency of thin film solar cell by investigating the properties which is related to it. The level of complexity involved is largely prohibitive to analytical treatment and hence numerical approaches are primarily utilized. The optimization is performed in MATLAB along with some other software like ORIGIN, WINDIG etc.
