Study and Analyze the Effect of Polymerization on Device Performance of P3HT: PCBM based Organic Solar Cell

This paper gives a comparison of photovoltaic performance of bulk hetrojunction solar cell using blends of P3HT and PCBM in 1: 1 ratio using common organic solvents by spin coating technique. Here different regioregular P3HT are used which were synthesised by various techniques. Prior to these processes, fabrication and designing of solar cells, right from the initial steps such as patterning of ITO coated glass, etching, cleaning and subsequent processes were performed. The main advantages of such cells are easy preparation, low process temperature, low cost materials& processing technology and the possibility to produce flexible devices on plastic substrates. Such flexible cells are therefore candidates for gamut of applications, from handheld electronics to commercial power production.
