3D Organic-Inorganic hybrid perovskite based Solar cells

Solution-processed organic-inorganic hybrid perovskite solar cells have been in the fore-front of global photovoltaic research. Considering the immense potential possessed by these materials due to its enhanced photophysical properties, and the rapid enhancement in power conversion efficiency, it is in the right path to replace the present silicon solar cell technology.

2D Layered Perovskite based Opto-electronic devices

Ruddlesden–Popper phase layered 2D perovskite materials gained importance due to its technologically relevant environmental and photostability, when compared to its 3D counterpart. The synthesis of layered 2D perovskites with higher  n values (n>3), having a broader light absorption have motivated us to use it as a light absorber in solar cells. 

Layered transition metal di-chalcogenides (TMD) for opto-electronic devices

In 2D transition metal di-chalcogenides (TMDs) field-effect transistors, the contacts between TMDs and different metals seem to play a major role in limiting the performances of these devices.

Phase-engineering method allows for transforming the TMD phase from 2H (semiconducting) to 1T-phase (metallic) under the contact thus reducing strongly the interface TMD/metal contact resistance while improving the field-effect transistor performances.

Photophysics and Opto-eletronic properties of 3D and 2D layered Perovskites

Understanding the fundamental properties of perovskites, in particular the optical properties and the kinetics of carriers – will be beneficial for improving the photo-voltaic devices reaching the Shockley-Queisser limit.
