“…Because of encouraging photo-conversion efficiency (PCE), dye sensitized solar Advances in Materials Physics and Chemistry cells (DSSCs) have been widely studied over the past twenty years [1]. Especially in the case of smaller market segments, DSSCs signify a workable substitute for silicon-based solar cells.…”

The aligned hexagonal cadmium sulfide nanorods (CdS NR) have been synthesized by hydrothermal technique at 200˚C on fluorine tin oxide (FTO) substrates. Dye sensitized solar cells (DSSCs) based on the photoelectrode core-shell CdS NR array with conductive polymers nanocomposite of polyaniline (PANI) and poly(3,4-ethylenedioxyl-thiophene)/poly(styrene-sulfonate) (PEDOT:PSS) were fabricated and designed with different types of dye molecules. DSSCs were characterized utilizing scanning electron microscopy (SEM), Raman scattering, energy dispersive spectroscopy (EDS), UV-Vis absorption spectroscopy, X-ray diffraction (XRD), and photocurrent-voltage (J-V) characteristic. Results show that under illumination (AM 1.5 G), the high power conversion energy (PCE) was achieved for CdS NR /PANI-PEDOT:PSS device when it sensitized with ruthenium (II) (dye N-719) of 0.91% and a short circuit current density (Jsc) of 4.21 mA/cm 2 in comparison with the other devices, which sensitized with natural dyes. The high performance of the CdS NR /PANI-PEDOT:PSS-N719 device attributed to the wide range of absorption and photostability for N719. This work shows that the CdS NR with N719 can be appropriate candidate for photovoltaics device for their low cost fabrication procedure and excellent absorption.

“…The optimal dispersion of CNSs in the polymeric matrix is in fact a requisite to create selective and well‐separated pathways for charge percolation in a specific direction (i.e., toward the collecting electrode) at the nanoscale level. This hinders undesirable back‐charge transfer processes, particularly for the case of SWCNTs . The prevention of aggregation for GBMs is also a key issue to preserve most of their unique properties, such as the high aspect ratio and electrical conductivity, associated to single or few layers graphene sheets .…”

Perovskite solar cells (PSCs) are demonstrating great potential to compete with second generation photovoltaics. Nevertheless, the key issue hindering PSCs full exploitation relies on their stability. Among the strategies devised to overcome this problem, the use of carbon nanostructures (CNSs) as hole transporting materials (HTMs) has given impressive results in terms of solar cells stability to moisture, air oxygen, and heat. Here, the use of a HTM based on a poly(3‐hexylthiophene) (P3HT) matrix doped with organic functionalized single walled carbon nanotubes (SWCNTs) and reduced graphene oxide in PSCs is proposed to achieve higher power conversion efficiencies (η = 11% and 7.3%, respectively) and prolonged shelf‐life stabilities (480 h) in comparison with a benchmark PSC fabricated with a bare P3HT HTM (η = 4.3% at 480 h). Further endurance test, i.e., up to 3240 h, has shown the failure of all the PSCs based on undoped P3HT, while, on the contrary, a η of ≈8.7% is still detected from devices containing 2 wt% SWCNT‐doped P3HT as HTM. The increase in photovoltaic performances and stabilities of the P3HT‐CNS‐based solar cell, with respect to the standard P3HT‐based one, is attributed to the improved interfacial contacts between the doped HTM and the adjacent layers.

The aim of this work was to characterize and evaluate the influence of the thickness on the photocatalytic efficiency of titanium dioxide thin films on the degradation of methyl orange dye under UV light irradiation. The films of 280 and 468 nm thick were deposited on borosilicate substrates at 400°C by the MOCVD technique using titanium isoproxide IV as precursor. XRD analyses showed the formation of anatase-TiO 2 phase. Crosssectional FE-SEM images show that the films presented a dense columnar structure and grown perpendicularly to the substrate surface. The photocatalytic activity of the catalysts was studied using UV-vis spectrophotometry The TiO 2 film with 468 nm of thickness presented higher photocatalytic activity exhibiting 69% of dye degradation. The increase of grain size and thickness of the films promoted an improvement of photocatalytic efficiency.
