研究领域
The research interest of Dr. Jain, targets on next generation photovoltaic materials, mainly perovskite solar cells (PSCs) and Organic solar cells.
Although, perovskite solar cells achieved 22 % record high efficiency for small modules, the toxicity of lead present in them and the stability of the solar cells still remains a hurdle for their commercialization.
Align in this direction, Sagar´s work is focused on several domains of research involving PSCs as:
Synthesis and characterization of new absorber materials, new interfaces as well single crystals for solar cells, designing new solar cell architectures – investigate structural, optical, and electronic properties by combining different experimental and characterization techniques.
Characterization techniques:
X-ray diffraction; Atomic force microscopy (AFM); Scanning electron microscopy (SEM); Transmission electron microscopy (TEM) and Kelvin probe
Spectroscopies: NEXAFS – Near edge X-Ray Absorption fine structure; HR-XPS – High resolution X-ray photoelectron; UV-Visible, Raman, Photoluminiscence etc
Interface engineering of Solar cells : development of 2D materials for high efficiency, low cost and stable hybrid solar cells and modules, utilizing graphene, carbon nanotubes, self-assembled monolayers (SAMs) and other 2D materials.
One of the aspect of the research is investigating the new lead-free perovskite materials to be used in solar cells as well investigation of stability of perovskite and organic photovoltaic solar cells.
In addition, Sagar is also finding alternative low cost and low temperature processed hole transport and electron transport materials for perovskite solar cells and development of new deposition techniques and methodology for preparation of perovskite solar cells.
