The Common

In the present work, chemical-free aluminium nanoparticles (Al NPs) have been incorporated inside active layer of organic solar cell (OSC) using a new ultrasonic ablation technique, by which the Al NPs have been physically prepared in 1,2-dichlorobenzene (DCB) as a solvent for preparing solar cell active layer. The concentration of Al NPs inside active layer can be increased by increasing the volume of DCB-Al NPs and, also, by increasing the ultrasonication time applied upon DCB-Al NPs mixture. The prepared Al NPs are incorporated inside the common P3HT:PCBM active layer without accumulation and with low distribution. Optical absorption of the P3HT:PCBM active layer is improved through plasmon resonance induced by Al NPs inside active layer. The fill factor (FF) is, also, improved by the presence of Al NPs which facilitate charge carrier transfer in the P3HT:PCBM solar cell. The FF can be reduced due to presence of Al bulk pieces inside active layer. However, these Al bulk pieces are dissociated under the effect of ultrasonic irradiation for longer time. Optical absorption as well as charge carrier transfer induced by Al NPs are the responsible to increase performance parameters of the P3HT:PCBM solar cell under increasing the concentration of Al NPs inside OSC. As a conclusion, the incorporation of Al NPs inside P3HT:PCBM solar cell induces a significant improvement of the FF by 35% and consequently, the PCE is improved with about 39%.

The Way

The electrophilic borylation of 2,5-diarylpyrazines results in the formation of boron-nitrogen doped dihydroindeno[1,2-<i>b</i>]fluorene which can be synthesized via mildly air-sensitive techniques and the end products handled readily under atmosphereic conditions. Through transmetallation via diarylzinc reagents a series of derivatives were sythesized which show broad absorption profiles that highlight the versatility of this backbone to be used in organic solar cell devices. These compounds can be synthesized in large yields, in alow number of steps and functionalized at many stages along the way providing a large depth of possibilities. Exploratory device paramaters were studied and show PCE of 2%.

Background: The photo-absorption and light trapping through the different layers of the organic solar cell structures are a growing concern now-a-days as it affects dramatically the overall efficiency of the cells. In fact, selecting the right material combination is a key factor in increasing the efficiency in the layers. In addition to good absorption properties, insertion of nanostructures has been proved in recent researches to affect significantly the light trapping inside the organic solar cell. All these factors are determined to expand the absorption spectrum and tailor it to a wider spectrum. Objective: The purpose of this investigation is to explore the consequence of the incorporation of the Ag nanostructures, with different sizes and structures, on the photo absorption of the organic BHJ thin films. Methods: Through a three-dimensional Maxwell solver software, Lumerical FDTD, a simulation and comparison of the optical absorption of the three famous organic materials blends poly(3- hexylthiophene): phenyl C71 butyric acid methyl ester (P3HT:PCBM), poly[N-9″-heptadecanyl-2,7- carbazole-alt-5,5-(4′,7′-di-2-thienyl-2′,1′,3′-benzothiadiazole)]: phenyl C71 butyric acid methyl ester (PCDTBT:PCBM) and poly[2,6-(4,4-bis-(2-ethylhexyl)-4H-cyclopenta[2,1-b;3,4-b′]dithiophene)-alt- 4,7-(2,1,3-benzothiadiazole)]: phenyl C71 butyric acid methyl ester (PCDPDTBT:PCBM) has been conducted. Furthermore, FDTD simulation study of the incorporation of nanoparticles structures with different sizes, in different locations and concentrations through a bulk heterojunction organic solar cell structure has also been performed. Results: It has been demonstrated that embedding nanostructures in different locations of the cell, specifically in the active layer and the hole transporting layer had a considerable effect of widening the absorption spectrum and increasing the short circuit current. The effect of incorporation the nanostructures in the active layer has been proved to be greater than in the HTL. Furthermore, the comparison results showed that, PCDTBT:PCBM is no more advantageous over P3HT:PCBM and PCPDTBT:PCBM, and P3HT:PCBM took the lead and showed better performance in terms of absorption spectrum and short circuit current value. Conclusion: This work revealed the significant effect of size, location and concentration of the Ag nanostructures while incorporated in the organic solar cell. In fact, embedding nanostructures in the solar cell widen the absorption spectrum and increases the short circuit current, this result has been proven to be significant only when the nanostructures are inserted in the active layer following specific dimensions and structures.
