Anode Buffer Layer

Previous study showed that the introduction of solution-dispersed copper iodide (CuI) as anode buffer layer has improved the performance of inverted type organic solar cell. However, the CuI preparation parameters have yet to be optimized for the inverted type organic solar cell. In this work, the effect of ultrasonic agitation of CuI solution on inverted type organic solar cell based on zinc oxide (ZnO)/poly(3-hexylthiophene) (P3HT):(6,6)-phenyl-C61-butyric acid methyl ester (PCBM) has been studied. ZnO, acting as electron transporter, was spin-coated on top of fluorine tin oxide (FTO) substrate, while the active layer consisting of P3HT:PCBM as the electron donor and electron acceptor was spin-coated onto the ZnO layer and the top electrode, silver (Ag) was then thermally evaporated. CuI dispersed in acetonitrile solution was ultrasonicated with durations of 10, 20 and 30 min and then was spin-coated on the active layer. It was found that solution-dispersed CuI with longer ultrasonic agitation duration attained a relatively higher PCE than that with shorter duration and the highest PCE was 2.13%, achieved at 30 min ultrasonic agitation due to good film surface morphology. For further optimization, the deposition of CuI was carried out using different spin coating speeds of 1000 and 3000 rpm. The optimum PCE obtained was 2.29 at a spin coating speed of 3000 rpm as a result of uniform layer of CuI.

Phthalocyanine Derivative

Purpose – The purpose of this paper is to study the optical and electrical characteristics of a single-junction solar cell based on a green-colour dye vanadyl 2,9,16, 23-tetraphenoxy-29H, 31H-phthalocyanine (VOPcPhO). The use of soluble vanadyl phthalocyanine derivative makes it very attractive for photovoltaic applications due to its tunable properties and high solubility. Design/methodology/approach – A photoactive layer of VOPcPhO has been sandwiched between indium tin oxide (ITO) and aluminium (Al) electrodes to produce a ITO/PEDOT:PSS/VOPcPhO/Al photovoltaic device. The VOPcPhO thin film is deposited by a simple spin coating technique. To obtain the optimal thickness for the solar cell device, different thicknesses of the photoactive layer, achieved by manipulating the spin rate, have been investigated. Findings – The device exhibited photovoltaic effect with the values of Jsc, Voc and FF equal to 5.26 × 10-6 A/cm2, 0.621 V and 0.33, respectively. The electronic parameters of the cell have been obtained from the analysis of current-voltage characteristics measured in dark. The values of ideality factor and barrier height were found to be 2.69 and 0.416 eV, respectively. The optical examination showed that the material is sensitive to light in the UV region between 270 nm and 410 nm, as well as in the visible spectrum within the range of 630 nm and 750 nm. Research limitations/implications – The solar cell based on a single layer of vanadyl phthalocyanine derivative results in low efficiency, which can be enhanced by introducing a variety of donor materials to form bulk heterojunction solar cells. Practical implications – The spin coating technique provides a simple, less expensive and effective approach for preparing thin films. Originality/value – A novel thin-film, single-junction organic solar cell, fabricated by using VOPcPhO, has been investigated for the first time ever. The vanadyl phthalocyanine derivative together with a donor material will have potential application for improved efficiency of the solar cells.
