A highly efficient flexible dye-sensitized solar cell based on nickel sulfide/platinum/titanium counter electrode
TL;DR: It may be said that the NiS/Pt/Ti counter electrode is a promising catalytic material to replace the expensive platinum in FDSSCs.
Journal ArticleDOI
Dye-Sensitized Solar Cells Based on
TL;DR: In this article, Bismuth titanate (Bi4Ti3O12) particles were synthesized by hydrothermal treatment and nanoporous thin films were prepared on conducting glass substrates.

TL;DR: In situ back-contact passivation (BCP) that reduces interfacial and extraction losses between the perovskite absorber and the hole transport layer (HTL) is reported and it is shown that a flat-band alignment between theperovskites and polymer passivation layers achieves a high photovoltage and fill factor.
Journal ArticleDOI
Enhanced cycling stability of LiMn2O4 cathode by amorphous FePO4 coating
TL;DR: In this paper, the performance of LiMn 2 O 4 at room and elevated temperatures is improved by FePO 4 modification through chemical deposition method, and the results show that the improvement can be attributed to the stabilization of spinel structures.
Journal ArticleDOI
Preparation and investigation of nano-thick FTO/Ag/FTO multilayer transparent electrodes with high figure of merit.
TL;DR: The effects of mid–layer Ag and top FTO layer on the structural, electrical and optical properties of FTO/Ag/FTO multilayered composite structures deposited on quartz glass substrates by magnetron sputtering at 100 °C have been investigated.
