  1. 11. Alternative Architectures of Quantum Dot Solar Cells

    University essay from KTH/Tillämpad fysikalisk kemi

    Author : Astrid Bergman; [2021]
    Keywords : Quantum dots; Solar cells; PbS; Alternative architectures; electron transporting layer; Kvantprickar; solceller; PbS; alternativa arkitekturer; elektrontransportlager;

    Abstract : Kvantprickar är intressanta för tillverkning av solceller på grund av möjligheten att justera bandgapet beroende på kvantpricksstorleken. I detta examensarbete har alternativa arkitekturer av PbS kvantprickssolceller testats samt att påverkan av olika lager har utvärderats. READ MORE

  3. 12. The use of graphene quantum dots as detection elements in nanomaterials-based sensors for forensic applications

    University essay from KTH/Tillämpad fysik

    Author : Xiaofan Ma; [2021]
    Keywords : Graphene Quantum Dots; Amphetamine; Cocaine; Chemical Sensor; Forensic Drugs; Grafenkvantprickar; amfetamin; kokain; kemisk sensor; rättsmedicinska läkemedel;

    Abstract : The large-scale abuse and addiction of narcotics such as amphetamine and cocaine have become a global problem. In this project, we innovatively use graphene quantum dots (GQDs) as a fluorescent sensor to detect and quantify amphetamine and cocaine. This technology will have broad forensic application prospects. READ MORE

  4. 13. Transport properties and full counting statistics of electrons in double quantum dots operated by Maxwell’s demon

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Keywords : quantum thermodynamics; thermodynamics; Maxwell s demon; electron transport; full counting statistics; quantum dots; rate equation; information-thermodynamics link; Physics and Astronomy;

    Abstract : During recent years, Maxwell’s demon has regained interest in the work of understanding the connection between thermodynamics and information theory. This thesis presents transport properties of electrons in a double quantum dot system operated by Maxwell’s demon. READ MORE

  5. 14. Manufacturing optimization and film stability analysis of PbS quantum dot solar cells

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Erik Bryngelsson; [2019]
    Keywords : Quantum dots; Solar cells; Photovoltaics; PbS; Optimization;

    Abstract : Semiconductor colloidal quantum dots have an interesting potential to increase solar cell efficiency, with strong absorption in the infrared region and a tunable band gap. In this work an attempt was made to adopt a manufacturing process for PbS quantum dot solar cells, proven successful at Uppsala University. READ MORE

  6. 15. Quantum Dot Movement on Human Lung Epithelial Cell Line

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Michael Luxemburg; Hanna Jönsson; [2016]
    Keywords : ;

    Abstract : Inhalationsläkemedel är den främsta behandlingsmetoden för lungsjukdomar såsom astma och KOL. Förutom medicinering inandas vi dessutom miljardtals luftmolekyler varje dag varav en del är föroreningar. Hur dessa ämnen påverkar lunghälsan beror i hög grad på spridningen över lungcellerna.
