The aim of this research is to study improvement of power conversion efficiency (PCE) of organic-inorganic hybrid bulk heterostructure solar cell prepared by rapid convective deposition as a function of concentration of zinc oxide additive. The structure of hybrid solar cell used in this research is ITO/ZnO/P3HT:PC70BM:ZnO(nanoparticles)/MoO3/Au. By adding 5 mg/ml of ZnO nanoparticles in the active layer (P3HT:PC70BM), the PCE was increased from 0.46 to 1.09%. In order to reveal the origin of improving efficiency, surface morphology and optical properties of active layers were investigated by atomic force microscopy (AFM) and UV-Visible spectroscopy, respectively. The results clearly indicate that the enhancement of solar cell efficiency results from (i) the proper phase sepharation of electron donor and acceptor in the active layer and (ii) the better absorption of the active layer. This research work introduces an alternative way to improve solar cell efficiency by adding ZnO into active layer.

ABSTRACTRelatively low efficiency is one of the main obstacles to overcome in the engineering of organic bulk heterojunction (BHJ) solar cells. Reduced graphene oxide (RGO), which has high conductivity, has been proposed to enhance the function of PCBM in the interfacial dissociation of excitons, but incorporating it into the hydrophobic photoactive polymers has proved challenging. Here we describe a novel technique for incorporating Au nanoparticles (AuNp) into the structure of the RGO. The AuNps then interact with the sulfur groups on the photoactive polymer component, while the RGO interacts via π – π stacking with the chemically similar PCBM, thereby anchoring the complex to the polymer interface. Graphene oxide was synthesized and then reduced in the presence of a gold salt. The resulting gold-functionalized RGO (AuRGO) sheets were characterized using TGA, FTIR, and TEM. The AuRGO was not soluble in chlorobenzene; however, in the presence of P3HT, the AuRGO dissolved, suggesting a reaction between the gold and the sulfur of the P3HT via a metal-thiolate bond. At 2 mg/ml, AuRGO increased the solar cell efficiency approximately 50% over the control, but higher concentrations produced large, columnar structures which blocked the electrode from having a uniform contact with the active layer.

The objective of this paper is to read the various substrates which are mounted on Gold plasmonic nanoparticle and how they enhance the efficiency of a solar cell. With the help of MIE scattering software, we found the different type of light inclusion and light scattering by Gold nanoparticles mounted on various substrates of a solar cell. The second objective of this paper is to learn the outcome of nanoparticle dimension and standard deviation on light scattering and absorption. The process of this work can be shortened as follows: The literature review on surface plasmons and how effects solar cell efficiency is done. The software MIEPLOTV4305 and how it is used for the research work were studied. Scrutiny of gold samples with different mediums and comparing the variations in peak wavelength using MIE PLOT software and graphs were placed. The outcome of particle dimension and standard deviation on CSCATTERING, CABSORPTION, QSCATTERING, and QABSORPTION were done.
