“…P3HT:ICBA was selected as the active layer for the bottom cell (device F and G). ICBA was selected as the acceptor, because the P3HT:ICBA active layer forms its optimal morphology in higher annealing temperature when compared with P3HT:PCBM [34,35,36]. Therefore, the P3HT:ICBA system promises a lower thermal degradation for tandem device fabrication, compared with the P3HT:PCBM system.…”

We propose a novel method to pattern the charge recombination layer (CRL) with a low-temperature solution-processable ZnO layer (under 150 °C) for organic solar cell applications. Due to the optimal drying process and thermal annealing condition, ZnO sol-gel particles formed a three-Dimensional (3D) structure without using a high temperature or ramping method. The generated 3D nano-ripple pattern showed a height of around 120 nm, and a valley-to-valley distance of about 500 nm. Based on this newly developed ZnO nano-ripple patterning technique, it was possible to pattern the CRL without damaging the underneath layers in tandem structure. The use of nano-ripple patterned ZnO as the part of CRL, led to the concomitant improvement of the power conversion efficiency (PCE) of about 30%, compared with non-patterned CRL device.

“…As a result, the device fabricated from mixed solvent as CF/CB showed a better PCE value of 3.7% in comparison with those fabricated from CF and CB mono solvents [81]. Using inverted polymer solar cell based on P3HT:ICBA, Lin et al [82] demonstrated that a mixture of DCB and CB may result in different phase separations because of differences in their boiling points. The active-layer drying time was controlled with a higher ratio of DCB to CB (0.8/0.2 mL), while horizontal phase separation was reduced by the addition of the conductive polymer polyvinyl carbazole (PVK) [82].…”

Recent Approaches to Controlling the Nanoscale Morphology of Polymer-Based Bulk-Heterojunction Solar Cells

et al. 2013

Abstract:The need for clean, inexpensive and renewable energy has increasingly turned research attention towards polymer photovoltaic cells. However, the performance efficiency of these devices is still low in comparison with silicon-based devices. The recent introduction of new materials and processing techniques has resulted in a remarkable increase in power-conversion efficiency, with a value above 10%. Controlling the interpenetrating network morphology is a key factor in obtaining devices with improved performance. This review focuses on the influence of controlled nanoscale morphology on the overall performance of bulk-heterojunction (BHJ) photovoltaic cells. Strategies such as the use of solvents, solvent annealing, polymer nanowires (NWs), and donor-acceptor (D-A) blend ratios employed to control the active-layer morphologies are all discussed.

“…The blend of P3HT (poly(3-hexylthiophene-2,5-diyl)) and PCBM ([6,6]-phenyl-C61 butyric acid methyl ester) is commonly used as active layer owing to the complete knowledge about the mechanism, , though the higher electron affinity of PCBM limit the open circuit voltage ( V oc ) to 0.6 V. A fullerene derivative ICBA (indene-C 60 bisadduct) with a higher LUMO energy level is applied to replace PCBM as the donor, − which results in higher V oc but sacrifices the short circuit current ( J sc ), and the final OPV performance will be enhanced.…”

In this work, lithium-doped zinc oxide nanoparticles (LZO NPs) with different Li/Zn molar ratios (Li/Zn = 0, 0.05, 0.2) are successfully prepared to form an electron transporting layer (cathode buffer layer) in the inverted-type P3HT:ICBA organic photovoltaic (OPV) devices. As compared with the undoped ZnO NPs buffer layer, a considerable improvement OPVs from 2.344% to 2.946% is obtained by using 5%-LZO NPs as a buffer layer, which owns J sc of 7.22 mA/cm2, V oc of 0.86 V, and FF of 47.4%. X-ray absorption near-edge structure (XANES) spectra show the increase of unoccupied O 2p-derived states in 5%-LZO NPs, which leads to better carrier conductance. The energy levels of defects in 5%-LZO NPs analyzed by photoluminescence are found to facilitate electron extraction to the cathode. Impedance measurement results indicate that the carrier lifetime is effectively increased to 2176 μs by applying the 5%-LZO NPs buffer layer, showing the improvement of carrier extraction efficiency and resulting in its progressive performance.
