Effect Of Surface

We present the results on the effect of surface morphology and dispersion media on the properties of PEDOT:PSS/n-Si hybrid solar cell containing functionalized graphene (Gr). The hybrid solar cells based on SiNWs showed higher power conversion efficiency (PCE) compared to the planar based cells due to suppressing the carrier recombination and improving carrier transport efficiency. The PCE of hybrid solar cells could be improved by adding Gr into PEDOT:PSS. Different solvents including deionized (DI) water, ethylene glycol (EG), and isopropyl alcohol (IPA) were used as media for Gr dispersion. The best performance was obtained for the cell containing Gr dispersed in EG with a measured PCE of 7.33% and nearly 13% and 16% enhancement in comparison with the cells using Gr dispersed in IPA and DI water, respectively. The increase in PCE is attributed to improving the carrier-mobility, electrical conductivity, PEDOT crystallinity, and ordering.

In this work, multiwalled carbon nanotubes (MWCNTs) are separated and cut into short pipes using a green tea solution and embedded at interface of poly(3,4-ethylenedioxythiophene):poly(stylenesulfonate) (PEDOT:PSS)/n-Si hybrid solar cells. Devices fabricated with embedding green tea modified MWCNTs show much better performance (10.02%) than that of a device without MWCNTs (9.2%) due to better hole transportation, easy exciton splitting, and suppression of charge recombination.

Solar energy is one in all few sources to renewable power and it is considerably critical in our each day lifestyles usage thus resulted to ensure the practicality and usefulness of the devices which regularly used to capture and manipulate solar energy. In this work, studies the effect of conjugated chlorophyll (iCHLO) on power conversion efficiency with relation of iCHLO where optical and electrical properties were investigated. These hybrid solar cells consist of combination of organic (Poly (3, 4-ethylenedioxythiophene): poly (styrenesulfonate) and iCHLO) and inorganic (Titanium Dioxide, TiO2) materials. These hybrid solar cells were fabricated bilayer of ITO/TiO2/PEDOT: PSS/iCHLO/Al. Chlorophyll compound (CHLO) was extracted from the Pandanus amaryllifolius leaves. CHLO undergoes conjugate process by oxidation polymerization using Ferric Chloride (FeCl3) as catalyst. Different percentage of FeCl3 was varied by 5%, 10% and 15% of CHLO molecular weight. Result shows that UV-Vis absorption spectra of CHLO was absorbed in the range of 400 nm – 600 nm (CHLO-PA) and 240 nm - 360 nm (iCHLO-PA). The highest power conversion efficiency (PCE) was obtained at 1.33% and electrical conductivity is 0.135 Scm1 for ITO/TiO2/PEDOT: PSS/iCHLO-PA 10% hybrid solar cell.

For reducing the production costs, decreasing the fabrication time and for practical applications used in roll-to-roll process for inverted organic solar cells (IOSCs), silver (Ag) back-electrode have been deposited from silver paste solution at room temperature using simple, cheap and easy manual spray method, with completely avoiding the use of thermal evaporation system for solar cell preparation. In addition, a layer of poly (3,4-ethylenedioxythiophene):poly (styrenesulfonate) (PEDOT:PSS) as a hole transporting layer have been deposited from an aqueous solution onto hydrophobic active layer without any chemical additives or additional treatments. For optimizing the Ag film, to be used as a back electrode in the IOSCs, series resistance of the indium tin oxide (ITO)/PEDOT:PSS/Ag device was measured at different compositions of silver paste dispersed in ethanol, different annealing temperatures and different silver paste amounts sprayed onto PEDOT:PSS layer. The dilution process of silver paste with ethanol is practical to reduce its commercial cost and to decrease its viscosity to be easily sprayed using spray gun for application in large scale production with avoiding solidification and fast curing at room temperature. Using the present method, the Ag electrode has been efficiently sprayed on the top of organic solar cells with low electrical resistance, large thickness and good hardness against crashes. We found that, the high thickness of both PEDOT:PSS layer and Ag electrode deposited on the top of solar cell active layer prevent and suppress oxygen penetration towards P3HT:PCBM active layer. Therefore, the optimized solar cell revealed good air stability, compared to their counterparts in other literatures, under ambient atmosphere with approximately 86% retention of their original conversion efficiency after 154 days. Our results indicate that the solution-processed Ag back-electrode using easy method has a potential to be used in roll-to-roll processed organic solar cells and other optoelectronic applications.

Cadmium Sulfide Nanoparticles

Cadmium sulfide nanoparticles (CdS-n) are excellent electron acceptor for hybrid solar cell applications. However, the particle size and properties of the CdS-n products depend largely on the synthesis methodologies. In this work, CdS-n were synthetized by microwave heating using thioacetamide (TA) or thiourea (TU) as sulfur sources. The obtained CdS-n(TA) showed a random distribution of hexagonal particles and contained TA residues. The latter could originate the charge carrier recombination process and cause a low photovoltage (Voc, 0.3 V) in the hybrid solar cells formed by the inorganic particles and poly(3-hexylthiophene) (P3HT). Under similar synthesis conditions, in contrast, CdS-n synthesized with TU consisted of spherical particles with similar size and contained carbonyl groups at their surface. CdS-n(TU) could be well dispersed in the nonpolar P3HT solution, leading to aVocof about 0.6–0.8 V in the resulting CdS-n(TU) : P3HT solar cells. The results of this work suggest that the reactant sources in microwave methods can affect the physicochemical properties of the obtained inorganic semiconductor nanoparticles, which finally influenced the photovoltaic performance of related hybrid solar cells.
