Abstract
A high-performance of a planar hetejunction structure is demonstrated by using Fullerene (C60) and Boron Subphthalocyanine Chloride (SubPc) sandwiched between a cathode and an anode, indium tin oxide (ITO) and aluminum (Al), respectively. Often, there will also exist a buffer layer such as Poly 3,4-EthyleneDioxyThiophene : Poly- Styrene Sulphonate (PEDOT:PSS) and Bathocuproine (BCP) between any active layer and adjacent electrode, which is responsible for increasing efficiency through modifying the work function and controlling exciton diffusion. The cell that we studied is composed of the following structure: ITO(30nm)/PEDOT:PSS(xnm)/SubPc(25nm)/C60(35nm)/BCP(ynm)/Al(30nm), with different value of x=5,10,12,15,20 nm and y=8,10,12,14,16nm. So, the aim of our work is to investigate the effect of PEDOT: PSS and BCP thicknesses on the efficiency of this organic solar cell.
