Facile and eco-friendly synthesis of water-soluble Cu2-xSe nanoparticles for photovoltaic applications
Water-soluble Cu2-xSe (x = 0.2) nanoparticles (NPs) were synthesized by an eco-friendly modified chemical co-precipitation method at 70 °C within a short reaction time of 15 min using ascorbic acid. Cu2-xSe NPs showed pseudo-spherical and hexagonal shapes with sizes in the range of 20–50 nm. XRD ana...

Cu2-xSe NPs showed pseudo-spherical and hexagonal shapes with sizes in the range of 20–50 nm. XRD analysis showed cubic structure to Cu2-xSe NPs. Thin films of Cu2−xSe were deposited by drop-casting the synthesized Cu2-xSe NPs solution using polyvinylpyrrolidone binder and their physical properties were investigated. The annealed Cu2-xSe NPs thin film showed a direct optical band gap of 1.82 eV and an indirect band gap of 1.69 eV. Hall Effect measurements of the annealed films showed p-type conductivity with a carrier concentration of 3.18 × 1019cm−3, resistivity of 1.31 × 10−1 Ω-cm, and hole mobility of 1.5 cm2/V-s. In order to investigate the potential of Cu2-xSe NPs as an absorber, solar cells with a device configuration of soda-lime glass (SLG)/Mo/Cu2-xSe NPs/CdS/i-ZnO/Al:ZnO/Ni/Ag were fabricated and tested, which showed a power conversion efficiency (PCE) of 0.095%. Even though the Cu2-xSeNPs solar cell showed low PCE, the use of environmentally benign reducer like ascorbic acid offers the benefit of eco-friendliness and compatibility of water-soluble Cu2-xSe NPs synthesis, and its ultimate use in solar cell as well as other applications. | ||

Hall Effect measurements of the annealed films showed p-type conductivity with a carrier concentration of 3.18 × 1019cm−3, resistivity of 1.31 × 10−1 Ω-cm, and hole mobility of 1.5 cm2/V-s. In order to investigate the potential of Cu2-xSe NPs as an absorber, solar cells with a device configuration of soda-lime glass (SLG)/Mo/Cu2-xSe NPs/CdS/i-ZnO/Al:ZnO/Ni/Ag were fabricated and tested, which showed a power conversion efficiency (PCE) of 0.095%. Even though the Cu2-xSeNPs solar cell showed low PCE, the use of environmentally benign reducer like ascorbic acid offers the benefit of eco-friendliness and compatibility of water-soluble Cu2-xSe NPs synthesis, and its ultimate use in solar cell as well as other applications.</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Cu2-xSe nanoparticles</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Cu2-xSe NPs thin film as absorber material</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="650" ind1=" " ind2="7"><subfield code="a">Modified chemical co-precipitation method</subfield><subfield code="2">Elsevier</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Minnam Reddy, Vasudeva Reddy</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Kotte, Tulasi Ramakrishna Reddy</subfield><subfield code="4">oth</subfield></datafield><datafield tag="700" ind1="1" ind2=" "><subfield code="a">Park, Chinho</subfield><subfield code="4">oth</subfield></datafield><datafield tag="773" ind1="0" ind2="8"><subfield code="i">Enthalten in</subfield><subfield code="n">Elsevier Science</subfield><subfield code="a">Narattha, Chalermphan ELSEVIER</subfield><subfield code="t">Thermal and mechanical characterization of fly ash geopolymer with aluminium chloride and potassium hydroxide treated hemp shiv lightweight aggregate</subfield><subfield code="d">2022</subfield><subfield code="g">Amsterdam [u.a.]</subfield><subfield code="w">(DE-627)ELV007709056</subfield></datafield><datafield tag="773" ind1="1" ind2="8"><subfield code="g">volume:112</subfield><subfield code="g">year:2020</subfield><subfield code="g">day:15</subfield><subfield code="g">month:06</subfield><subfield code="g">pages:0</subfield></datafield><datafield tag="856" ind1="4" ind2="0"><subfield code="u">https://doi.org/10.1016/j.mssp.2020.105013</subfield><subfield code="3">Volltext</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_USEFLAG_U</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">GBV_ELV</subfield></datafield><datafield tag="912" ind1=" " ind2=" "><subfield code="a">SYSFLAG_U</subfield></datafield><datafield tag="936" ind1="b" ind2="k"><subfield code="a">56.45</subfield><subfield code="j">Baustoffkunde</subfield><subfield code="q">VZ</subfield></datafield><datafield tag="951" ind1=" " ind2=" "><subfield code="a">AR</subfield></datafield><datafield tag="952" ind1=" " ind2=" "><subfield code="d">112</subfield><subfield code="j">2020</subfield><subfield code="b">15</subfield><subfield code="c">0615</subfield><subfield code="h">0</subfield></datafield></record></collection>
