Studies of the organic–inorganic hybrid perovskite, CH<sub>3</sub>NH<sub>3</sub>PbI<sub>3</sub>, doped with Sn<sup>2+</sup>, Sr<sup>2+</sup>, Cd<sup>2+</sup>and Ca<sup>2+</sup>.
A good correlation was obtained between the electronic properties of Cu-doped anatase TiO2 by virtue both physical chemistry characterization and theoretical calculations. Pure were synthesized. The composition, structural properties, band gap energy using several techniques. method synthesis used produces TiO2, XRD, XPS Raman spectroscopy indicate that Cu atoms are incorporated in structure substitution Ti atoms, generating a distortion oxygen vacancies. In turn, synthesized samples...
Meeting the growing energy demand with lowest environmental impact is one of greatest challenges facing our society. To this end, improving efficiency solar technologies a must. In work, nanofluids based on linear silicone-based fluid and Pd nanoparticles were prepared. The has been designed for use in concentrated power involving parabolic trough collector technology (CSP-PTC). showed high physical chemical stability. addition, Pd-based enhanced isobaric specific heat thermal conductivity...
Concentrating solar power is becoming one of options for producing energy to replace conventional polluting sources. However, improving the efficiency and reducing cost technologies based on this type make it more competitive still a work in progress. This study proposes replacing thermal oil used as heat transfer fluid absorber tubes parabolic trough collectors (PTCs) with nanofluids spherical molybdenum disulphide nanoparticles aim concentrating plants. The colloidal stability was verified...
Nanofluids are considered as a new generation of heat transfer fluids since they exhibit thermophysical properties improvements compared with conventional fluids. The high thermal conductivity nanofluids and even the isobaric specific enhancements over liquids make these colloidal suspensions very attractive in many research areas, including solar energy. In this work, based on tungsten disulphide (WS2) nanosheets have been prepared from oil currently used fluid Concentrating Solar Power...
Diamonds can host a variety of luminescent point-defects, such as nitrogen-vacancies and silicon-vacancies, making them remarkably promising materials for luminescence nanothermometry. It also fulfils the desirable characteristics low cytotoxicity...
This study explores the potential use of CuO nanofluids in a polydimethylsiloxane (PDMS) fluid for concentrating solar power (CSP) applications. The research addresses need environmentally friendly and efficient heat transfer fluids as alternatives to traditional options, which often pose environmental toxicity concerns. PDMS fluids, while offering benefits like high resistance low pour points, suffer from lower thermal conductivity capacity. addition nanoparticles aims enhance these...
Abstract TiO 2 doping has been widely used in photocatalysis and photovoltaic cells to improve the performance of this semiconductor. This paper studies use copper as a dopant dye‐sensitized solar (DSSC), analysing effect on properties different concentrations incorporated into The copper‐doped semiconductor was characterized with several instrumental techniques, including X‐ray diffraction (XRD), inductively coupled plasma atomic emission spectroscopy (ICP‐AES), scanning transmission...
This paper presents the synthesis of organic-inorganic hybrid perovskite CH3NH3Pb1-xCdxI3. The effect incorporating Cd(2+) or Pb(2+) on stability structure was analysed from a theoretical and experimental viewpoint. XRD results showed that tetragonal formed for x values up to 0.5, which seems indicate presence considerable amount is necessary stabilise structure. In turn, UV-Vis spectroscopy how led reduction in optical band gap 9% CH3NH3Pb0.5Cd0.5I3 with regard MAPbI3 Moreover, periodic-DFT...
