Perylene 3,4,9,10-tetra carboxylic dianhydride (PTCDA) thin films find a lot of optoelectronic applications. In this work, thin films of PTCDA were deposited using vacuum evaporation technique onto clean glass substrates and the variation in conductivity, optical bandgap and percentage transmission due to iodine doping for different time intervals are discussed. To study the doping effects on devices, organic solar cells based on cobalt phthalocyanine (CoPc)/PTCDA as active layers on indium tin oxide–coated glass substrates were fabricated and characterized to evaluate the solar cell parameters. It was found that doping with iodine considerably increases the power conversion efficiency of the solar cells.

After the breakthrough of conducting polymers, an incredible interest has been paid to integrate them in electronic component fabrication as an alternative to metals. Polyaniline is the most extensively studied material due to the ease of synthesis, better environmental stability, and enormous scope to modify its properties for solar cell applications. The electrical conductivity of PANI can be altered according to the need for the application where electronic devices made of conducting polymer composites are significantly dependent on the dielectric properties of the materials. Therefore, this chapter has been dedicated to the low-frequency AC conduction and dielectric studies of conducting PANI followed by having PANI thin films as efficient donor or acceptor bulk heterojunction layer to the hybrid solar cells.

Electron Donor And Acceptor

This paper reports an application of Atomic Force Microscopy (AFM) phase imaging to observe the phase separation between electron donor and acceptor materials in bulk heterojunction organic solar cells. The solar cells were fabricated using inkjet printed thin films of blended poly (3-octylthiophene-2,5-diyl)(P3OT) and (6,6)-phenyl C71 butyric acid methyl ester (PC71BM) as donor and acceptor materials respectively. The content PC71BM in the blended was varying from 25, 50 and 75 wt %. The AFM phase images of the thin film which contains 25 wt % PC71BM indicated that the acceptor molecules, PC71BM, are well distributed in the polymer chain of donor material, P3OT. The solar cell contains this film has the highest generated photocurrent. Hence, the phase separation between electron donor and acceptor materials in bulk heterojunction organic solar cells is one essential aspect that influences generation of photocurrent.
