“…Then, the solution was continuously stirred for 3 hours at room temperature and then poured into a container with an Al: ZnO seed coated glass substrate inserted into the container. The immersion process was done by immersing sealed vessels inside the water bath for 60 minutes at 95°C for nanorod growth [23]. For the second immersion process, GO solution with different concentrations (0, 0.2, 0.3, 0.4, 0.5, and 0.6mg/ml GO) was poured into each vessel onto the ZnO nanorods.…”

In this present work, the effects of coating of graphene oxide (GO) at different concentrations (0, 0.2, 0.3, 0.4, 0.5, and 0.6 mg/ml) onto zinc oxide (ZnO) nanostructured were investigated. ZnO and ZnO coated with GO (ZnO/GO) were prepared using immersion method. The structural, morphology and optical properties of all samples have been studied using x-ray diffraction (XRD), field emission scanning microscopy (FESEM) and UV Vis spectroscopy. The peak obtained from the XRD pattern shows that all samples are in the hexagonal-wurtzite structure. The (002) peak shows the strongest intensity for all samples with the highest (002) peak obtained for the ZnO/GO sample coated at a GO concentration of 0.5 mg/ml. The diameter of ZnO/GO nanostructured samples decreased after coating with GO at concentrations of 0.2 to 0.5 mg/ml and the diameter increased again when ZnO nanostructures were coated with GO at above 0.5 mg/ml. The highest transmission spectrum was obtained for the ZnO/GO sample coated with GO at a concentration of 0.5 mg/ml. In conclusion, the effect of GO coating on ZnO nanostructured can be changed at different concentrations of GO. The optimal properties of ZnO/GO may be suitable as a photoanode in DSSC applications.

“…Sol-gel immersion has high quality of aligned ZnO nanorods. This method was started with preparing the solution by a sonicated sol-gel and immersion method to grow ZnO nanorods [70]. Moreover, this method has low cost production, simplicity, capability to control the growth of ZnO nanorods and low temperature deposition process.…”

Dye sensitized solar cells (DSSCs) merupakan teknologi alternatif fotovoltaik yang menguntungkan. DSSCs menunjukkan harga yang murah, efisiensi yang tinggi dan proses pembuatan yang sederhana. Dalam aplikasi DSSCs, fotoanoda memiliki peranan yang penting untuk mengumpulkan elektron-elektron yang tereksitasi dan dye berfungsi untuk menyalurkan cahaya elektron-elektron ke transparent conducting film (TCF). Fotoanoda mempunyai band gap yang lebar pada semikonduktor logam oksida (contoh: zinc oxide (ZnO) dan titanium dioxide (TiO2)) yang dilapiskan pada TCF. Counter electrode (CE) adalah salah satu komponen yang penting dalam proses kerja DSSCs. CE digunakan sebagai mediator untuk membangkitkan sensitizer setelah masuknya elektron. Bahan CE yang ideal harus mempunyai resistansi yang rendah, biaya produksi yang murah, konduktivitas listrik yang tinggi, aktivitas elektrokatalitik yang bagus dan stabilitas yang tinggi. Bahan-bahan CE yang umum digunakan untuk aplikasi DSSCs yaitu seperti platina (Pt), karbon, carbon nanotubes (CNTs), grafin dan polimer konduktif. Review ini dikembangkan untuk mempelajari sifat-sifat bahan fotoanoda dan CE yang bagus untuk aplikasi DSSCs. Review ini juga digunakan untuk memberikan informasi untuk perkembangan bahan-bahan fotoanoda dan CE pada penelitian selanjutnya dalam aplikasi DSSCs. Dalam review ini, pengaruh bahan-bahan yang digunakan untuk fotoanoda dan CE dalam aplikasi DSSCs didiskusikan.

“…In 2013, Research on the fabrication of MEH-PPV [2-methoxy-5-(2 -ethylhexyloxy)p-phenylenevinylene]/Al:ZnO nanorod arrays based on ordered bulk heterojunction hybrid solar cells) has resulted in high performance (Jsc = 5.32 mA/cm 2 , Voc = 195 mV, FF = 27.71%,and EFF = 0.287%), an average optical transmission of approximately 78%, and an improved absorption coefficient compared to the catalyst layer seeded [12]. On the other hand, in 2014, an Experimental study of aligned ZnO nanorods on ZnO thin films doped with 2% Sn yielded high transmittance in the visible region, a large area with longer aligned ZnO nanorods, and improved performance (short-circuit current density Jsc = 2.840 mA/cm 2 , open-circuit voltage Voc = 0.552, fill factor FF = 0.381, and the power conversion efficiency of 0.599%) compared to the undoped film [13]. Also, in 2015, Jalal Rouhi et al showed that vertically aligned ZnO-ZnS core-shell nanocone arrays can be useful for optoelectronic devices due to a good surface-to-volume ratio, good electrical performance (Jsc = 12.2 mA/cm 2 , Voc = 0.68 V, and FF = 0.49), better light trapping, and longer life than the other structures [14].…”

The numerical modeling of Cu2ZnSnS4 solar cells with ZnO/CdS core-shell nanowires of optimal dimensions with and without graphene is described in detail in this study.The COMSOL Simulation was used to determine the optimal values of core diameter and shell thickness by comparing their optical performance and to evaluate the optical and electrical properties of the different models. The deposition of a nanolayer of graphene on the layer of MoS2 made it possible to obtain a maximum absorption of 97.8% against 96.5% without the deposition of graphene.The difference between generation rates and between recombination rates of electron–hole pairs of models with and without graphene is explored.The electrical parameters obtained, such as the filling factor (FF), the short-circuit current density (Jsc), the open-circuit voltage (Voc), and the efficiency (EFF) are, respectively, 81.7%, 6.2 mA/cm2, 0.63 V, and 16.6% in the presence of graphene against 79.2%, 6.1 mA/cm2, 0.6 V, and 15.07% in the absence of graphene. The suggested results will be useful for future research work in the field of CZTS-based solar cells with ZnO/CdS core-shell nanowires with broadband light absorption rates.
