Abstract

High purity light sensitive photoactive protein Bacteriorhodopsin (BR) was isolated successfully via a simple two phase extraction technique (ATPS) as an alternate method for the tedious sucrose gradient ultracentrifugation procedure (SGU). Bio sensitized solar cells (BSSCs) were fabricated by the integration of BR into TiO2 (photo anode) with acetamide based gel electrolytes and platinum (photo cathode) as a counter electrode. The structural and photoelectrical behaviours of BR and BSSCs were analyzed by Atomic Force Microscopy, Raman spectroscopy, photocurrent and photovoltage (IV) measurement and electrochemical impedance spectroscopy. The short circuit photocurrent (Jsc) and photoelectri..
