The excellent characteristics of graphene (optical and electrical) make it a better choice for photovoltaic applications. In this work, graphene has been synthesized by chemical oxidation of graphite (modified Hummers method) and subsequently its reduction to graphene. Furthermore reduced graphene oxide has been spin-coated on crystalline silicon (1 0 0) of both n and p-types to make the heterojunction solar cells. A through material and device characterizations have been made to understand the junction characteristics.

Sanjay Behura is presently working as Junior Scientist at Gujarat Energy Research and Management Institute in Gandhinagar, India. He has submitted his Ph.D. thesis in Materials Physics to Pandit Deendayal Petroleum University, Gandhinagar based on his research work at the University of Saskatchewan, Canada under Commonwealth Graduate Scholarship (2011-12). He is interested in junction characteristics of graphene-on-semiconductors for photovoltaic applications. He has published 17 international peer-reviewed papers in SCI Journals and refereed conference proceedings. He has received various academic awards and scholarships such as: Best Science Graduate Award (2006), IIT-GATE in Physics (2009), Joint CSIR-UGC NET in Physical Sciences (June 2009), Canada Commonwealth Graduate Scholarship (2011-12), Best Poster Prize in WRETC (2013) and DST Award of International Travel Support Scheme for Young Scientists (2014).
