Early life and career

Subhendu Guha was born in 1942 in Dhaka. Subhendu studied at Presidency College, Kolkata, and obtained his M.Tech. and PhD from the University of Calcutta.^[3]

Subhendu developed a new process for making Amorphous silicon in 1979 after he joined Tata Institute of Fundamental Research, Mumbai in 1968.^[4]

In 1991, he led a team of scientists at United Solar that made innovations to achieve efficiency solar cells and modules using Thin-film solar cell silicon and also the invention of flexible solar roofing shingles.^{[citation needed]}

In 2006, when Subhendu was President of United Solar, he discussed solar technology with former President George W. Bush during the president's visit to United Solar.^[5][6] He has also served as a panelist on the US Senate committee on energy and natural resources.^[7]

Awards and recognition

Subhendu is a recipient of the Bright Light Award from the US Department of Energy,^[8] and the PVSEC 2009 award for outstanding contribution to science and technology of photovoltaic.^[9]

He also received the World Technology Award^[1] and the Best of the Best Award from ABP Ananda for his contribution to science.^[10]
