“…Song et al . incorporated the CNTs into TiO 2 NR (CTNRs) by electrospinning, and after hydrothermal treatment, calcination, and ultrasonic treatment, they synthesized the branched TiO 2 NT (BTNTs) . The bilayer photo‐anodic films composing of the light scattering over layer of BTNTs and the under layer of CTNRs were fabricated for DSSCs.…”

The key to improving the performance of dye-sensitized solar cells is the photo-anode that has much dye adsorption and short optoelectronic transmission path. Electrospun TiO 2 films in photo-anode have high specific surface area and meet the demand exactly. The article summarizes these efforts in TiO 2 photo-anode improvement, including various morphology, different onedimensional and two-dimensional composite structure, and varied element doped TiO 2 photo-anode. Besides, the review makes comparison with these different TiO 2 photo-anodes in photoelectric properties. The conclusions provide a clear guidance in design of morphology, structure, and doping, which is helpful for researcher to improve the performance of the anode and increase the photoelectric conversion efficiency especially those prepared using electrospinning.

“…Conventional DSSCs with CNTs incorporated into them exhibited over 12% conversion efficiency [47]. Carbon nanotubes can be used as a substrate to grow branched TiO 2 crystals which improve light scattering / dye loading, and allow for more effective electron collection by increasing the surface area of the oxide layer [48]. This CNT/TiO 2 nanorod system shows great application for flexible DSSCs (Figure 6), with conversion efficiencies of up to 4.18% [48].…”

Advancements in dye-sensitized solar cell (DSSC) technology are occurring at an everincreasing rate, as the development of novel carbon-based materials, the increasing research into new 3D surface morphologies and cell design, and the focus on the development of new sensitizers and electrolytes have allowed many new possibilities for DSSCs. Solar cells that are three-dimensionally structured offer significant advantages over traditional crystalline / semicrystalline panels in that they can convert incident photons that strike them at large incident angles, can be flexible / used in applications which require non-rigid materials, and can be substantially cheaper to produce than traditional panels, especially with the replacement of more expensive, traditional electrode materials by carbon materials in the working / counter electrode.The use of carefully selected and engineered sensitizers like quantum dots with these threedimensionally structured solar cells have seen them achieve ever-increasing power conversion efficiencies, and it's likely that they will soon rival traditional crystalline / semi-crystalline panels for both mass power generation and use in more niche applications such as flexible photovoltaic textile fibers. This review covers DSSCs constructed with several different materials, and the advantages and disadvantages of a variety of cell designs.

“…Single-walled nanotubes are generally figured as a single sheet of graphene rolled and formed in a hollow cylindrical shape whereas multi-walled CNTs consisted of multiple concentric sheets with typically 5-50 nm in diameter and 10 μm in length (Yeoh et al 2012). CNTs are electrically conductive with great thermal conductivity compare to diamond and have extended too many applications such as thermal interface materials (Xu et al 2008), solar cells (Song et al 2016), batteries (Kim et al 2010) and energy storage (Cott et al 2013).…”

Thermal interface materials (TIMs) are applied in packaging of electronic devices for heat dissipation purposes. Carbon nanotubes (CNTs) are promising material due to their high thermal conductivity properties which will give optimum performance as TIMs. In this research study, electrophoretic deposition (EPD) is used which enables the deposition process conduct at room temperature with simple equipment setup which beneficial for CNTs deposition. As-produced CNTs was purified and directly deposited on heat spreader using direct current (DC) electricity. Dimethylformamide (DMF) was used as suspension medium for CNTs and the effect of suspension concentration was studied. From the screening of suspension concentration, 0.50 mg/mL yielded good deposition with thickness of 4.78 µm of CNTs deposited on heat spreader at applied voltage of 150V and 10 min deposition time. Further studied in different applied voltage and voltage of 250 V shows the maximum thickness of 15.01 µm with 2.0 mg weight of deposited CNTs which is suitable for fabrication of TIM. ABSTRAKBahan antara dua muka haba diaplikasikan dalam pakej alatan elektronik untuk tujuan pelesapan haba. Karbon tiub nano (CNT) dipilih kerana ia mempunyai konduktiviti haba baik yang dapat memberi prestasi optimum sebagai bahan antara dua muka haba. Di dalam kajian ini, pengendapan elektroforesis (PE) adalah digunakan bagi membolehkan proses pengendapan dilakukan pada suhu bilik berserta pemasangan alatan yang ringkas iaitu bermanfaat dalam pengendapan NK. NK yang telah dihasilkan kemudiannya ditulenkan dan diendapkan terus di atas penyebar haba menggunakan elektrik arus terus (AT). Dimetilformamida (DMF) digunakan sebagai medium ampaian untuk NK dan kesan kepekatan ampaian telah dikaji. Kepekatan ampaian, 0.50 mg/mL menghasilkan endapan NK yang baik dengan ketebalan 4.78 µm di atas penyebar haba pada voltan gunaan 150V dan 10 min masa endapan. Kajian diteruskan bagi voltan gunaan yang berbeza dan menunjukkan voltan gunaan 250V menghasilkan tebal maksimum 15.01 µm dengan 2.0 mg berat endapan NK yang sesuai untuk fabrikasi bahan antara dua muka haba.Kata kunci: Bahan antara dua muka haba; nanotiub karbon; pengendapan elektroforesis
