Efficiency and stability are the main challenges of organic solar cells. In this research novel structure is investigated for organic solar cell which has improved efficiency and improved stability. Blend of PTB7 and PCBM elements was used for the active layer of cell. Thickness of this layer was varied from 80nm to 200nm and selected the optimized thickness of 90nm. On which the cell has maximum efficiency of 12.24 %. The influence of window layer material such as Zinc oxide (ZnO) and titanium dioxide (TiO2) with various electrode materials including Indium tin oxide (ITO), Fluorine tin oxide (FTO), aluminum (Al) Silver (Ag) and Gold (Au) with different combinations have been investigated with the objective to enhance the absorption and PCE of the cell. Also varied the thicknesses of these different layers and selected the optimized thickness on which the cell had maximum efficiency. The structure of the proposed scheme was observed with ITO/Al as top and bottom electrode with thicknesses of 125nm and 100nm respectively and found that this holds the highest performance parameters including Jsc=0.130(mA/m2), Voc= 1 (V), FF=94.1% and ƞ=12.24% respectively as compared to different electrode combination and window layers with the same photoactive absorber material PTB7: PCBM. This indicates that the proposed structure can be a good choice for replacing less efficient in-organic cell.

Electrical Simulation

The growing requirement for electricity and its inadequate fossil fuel supply is a global concern that's why organic solar cell (OSC) devices had more attraction in the last decades for their practical application. In this research study, GPVDM software is considered, a 3-D photovoltaic device model, used to observe the outcomes of PTB7: PC70BM based organic solar cell. The organic solar cell comprises a PTB7:PC70BM as an active layer, indium tin oxide (ITO) serving as a transparent conducting oxide, and front electrode, PEDOT: PSS for efficient transporting of holes, while Al is taken as a back metal electrode. The electrical simulation via GPVDM has been performed at different active layer thicknesses and charge carrier mobility. Furthermore, the influence of varying different HTM layers had also been studied. The optimum efficiency of OSC is obtained at 200 nm active layer thickness and carrier mobility of 2.46 x 106 m2/Vs. The outcomes and performance of the simulated organic solar cell are compared with the practically implemented organic solar cell. This research also suggests a possible path toward the efficient implementation of organic solar cells by modifying factors that are significantly reliant on the performance and outcomes of OSCs.

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%.

Organic solar cells have potential as an alternative to conventional inorganic solar cell due to low processing cost, flexibility and easy fabrication technique. The goal of this paper is to study the characteristics of the CuPc and PCBM based organic solar cell by introducing a thin layer of Ag at the interface of donor (CuPc) and Acceptor (PCBM), their photovoltaic and optical properties were investigated. The heterojunction solar cells with and without silver inter layer were fabricated through thermal deposition in HR vacuum. The OPV solar cells were characterized using current-voltage graphs, absorbance spectrum and Impedance spectroscopy. Impedance spectroscopy was taken to identify the traps using series resistance, parallel resistance, and Impedance spectrums under different frequencies. Optical behaviors of these devices have been investigated with absorbance spectrum. Introducing Ag to interfacing point produced traps and these traps causes to decreased Voc, Isc, FF, and efficiency. The effect of silver layer at donor acceptor interface was studied.
