Abstract Carbon/graphite nanocomposite (CGn) film had been employed as cathode for hole transport layer (HTL) free, mesoscopic, heterojunction perovskite solar cells (PSCs). Hydrophobic CGn film shows impressive charge transport characteristics that makes it promising candidate for cathode in HTL free PSCs. The electrochemical impedance spectroscopy measurements realised the significant charge transport characteristics can get for (10 μm–14 μm) thin film. On the other hand, the hydrophobic (Cont...

Metal halide perovskites (MHPs) have excellent optoelectronic and photovoltaic applications because of their cost-effectiveness, tunable emission, high photoluminescence quantum yields, and excellent charge carrier properties. However, the potential applications of the entire MHP family are facing a major challenge arising from its weak resistance to moisture, polar solvents, temperature, and light exposure. A viable strategy to enhance the stability of MHPs could lie in their incorporation into...

In the last few decades, dye-sensitized solar cell (DSC) technology has been demonstrated to be a promising candidate for low cost energy production due to cost-effective materials and fabrication processes. Arguably, DSC stability is the biggest challenge for making this technology appealing for industrial exploitation. This work provides further insight into the stability of DSCs by considering specific dye–electrolyte systems characterized by Raman and impedance spectroscopy analysis. In part...

Perovskite and dye-sensitized solar cells are PV technologies which hold promise for PV application. Arguably, the biggest issue facing these technologies is stability. The vast majority of studies have been limited to small area laboratory cells. Moisture, oxygen, UV light, thermal and electrical stresses are leading the degradation causes. There remains a shortage of stability investigations on large area devices, in particular modules. At the module level there exist particular challenges whi...

This work provides further insight on the long term stability, of Dye Sensitized Solar Cells (DSCs) assessed through prolong thermal aging at 85°C in dark. The investigation is focused on Bis(isothiocyanato)(4,4′-dicarboxylato-2,2′- bipyridine)(4,4′-dinonyl-2,2′-bipyridine)ruthenium(II) (Z907) sensitized devices employing commercially available ionic liquid electrolyte (livion 12, L12) with high boiling point. The electrical performance (measured under 1 Sun irradiation condition) of the investi...

Abstract An electrochemical biosensor based on manganese oxide (Mn 3 O 4 ) and chitosan (Cn) nanocomposite has been fabricated for fish freshness detection. The electrophoretic deposition of Mn 3 O 4 nanoparticles (15–20 nm) with Cn has changed their morphological arrangement leading to pearl shaped of Mn 3 O 4 –Cn nanocomposite on indium tin oxide substrate. Size and morphology of nanocomposite have been confirmed by high resolution transmission electron microscopy (HRTEM), X-ray diffraction (X...

Abstract We have fabricated the chemically functionalized multi-walled carbon nanotubes (MWCNT) electrophoretically deposited onto indium tin oxide for urea detection. Urease and glutamate dehydrogenase are attached to MWCNT/ITO electrode surface covalently using ethyl-dimethylaminopropyl-carbodiimide and N-hydroxysuccinimide coupling chemistry. Excellent electrochemical properties of MWCNT and covalent functionalization of dual enzyme improve biosensor stability and sensitivity. The electrochem...
