Study and Analyze the Effect of Hole Transport Layer on the Power Conversion Efficiency of P3HT:PCBM based Organic Solar Cell

Shagun Malhotra ^[6] | Lalit Goswami ^[2]

Abstract: Organic solar cell research has attracted scientific and commercial interest in the last decade due to a rapid increase in power conversion efficiencies (PCEs). The most-prominent reported material system in Bulk Heterojunction (BHJ) is the mixture of poly (3-hexylthiophene) and [6, 6]-phenyl-C61-butyric acid methyl ester (P3HT: PCBM). Due to the various research efforts that have been done on the improvement of solar cells, the effect of Hole Transport Layer (HTL) was also noticed as an important factor. This paper gives a effect of different HTL materials like PEDOT: PSS (poly (3, 4-ethylenedioxythiophene): poly (4-styrenesulfonate) and MoO3 (Molybdenum trioxide) on the photovoltaic performance of BHJ solar cell using blends of P3HT and PCBM in 1: 1 ratio using common organic solvents. 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.
