Title of Seminar
"Systematic Development, Synthesis and Applicati on of New ‐Conju gated Compounds for Organic Solar Cell Devices" by Dr. Shreyam Chatterjee

Abstract
Organic Solar Cell (OSC) is a promising alternative for clean and rene wable ener gy due to their potential to be fabricated onto large area, light-weight fle xible substrates by s olution processing at low cost. Development of new π-conjugated syste ms has become a key factor for the advancement of OSC research into a next level upto commercialization. Systematic developm ent and synthesis of new n-ty pe - conj ugated compounds containing different building blocks such as 2,1,3-benzobisthiadiazole (BTz), naphtho[1,2-c:5,6-c'] bis[1,2,5]thiadiazole (N Tz), fluorinated naphtho[1,2-c:5,6-c']bis[1, 2,5]thiadiazole (FN Tz) etc. their structure-pro perty relationships will be discussed. Furt hermore, a pplication of these newly synthe sized com pounds as nonfulleren e acceptor into OSC device with poly(3-h exyl thiophene) (P3H T) as a wid e band gap donor will be present ed in details.
