  4. 3. Advanced rear contact design for CIGS solar cells

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jorge Alexandre De Abreu Mafalda; [2019]
    Nyckelord :CIGS; HfO2; surface passivation; alkali treatment; point contact openings; SCAPS;

    Sammanfattning : The current trend concerning the thinning of solar cell devices is mainly motivated by economic aspects, such as the cost of the used rare-earth elements, and by the requirements of emergent technologies. The introduction of ultra-thin absorber layers results in a reduction of used materials and thus contributes to a more cost-effective and time-efficient production process. LÄS MER

  5. 4. Stacked Dual Narrowband Organic Near-Infrared Photodetectors

    Master-uppsats, Linköpings universitet/Institutionen för fysik, kemi och biologi

    Författare :Yazhong Wang; [2017]
    Nyckelord :Near-infrared; photodetectors; CT states; Fabry-Perot resonant cavity; resonant cavity enhancement; tunability; full width at half maximum;

    Sammanfattning : Compared with the detector devices made of inorganic semiconductors, organic photodetectors are granted with additional strengths, such as flexibility, high scalability and bio-compatibility. However, in the family of organic optoelectronic devices, the detectors that are capable of detecting photons at two or multiple specific wavelengths are still missing. LÄS MER

  7. 5. Surface energy modification of metal oxide to enhance electron injection in light-emitting devices : charge balance in hybrid OLEDs and OLETs

    Master-uppsats, Högskolan i Gävle/Avdelningen för elektronik, matematik och naturvetenskap

    Författare :Sergio Apicella Fernandez; [2017]
    Nyckelord :organic; inorganic; semiconductors; OLEDs; OLETs; TFT; stack; thin-film; deposition; spin-coating; thermal; evaporation; process; reactive; sputtering; luminescence; EQE; PEIE; metal-oxide; ZnO; ZnO:N; MoO3; F8BT; Alq3; NPB;

    Sammanfattning : Organic semiconductors (OSCs) present an electron mobility lower by several orders of magnitude than the hole mobility, giving rise to an electron-hole charge imbalance in organic devices such as organic light-emitting diodes (OLEDs) and organic light-emitting transistors (OLETs). In this thesis project, I tried to achieve an efficient electron transport and injection properties in opto-electronic devices, using inorganic n-type metal oxides (MOs) instead of organic n-type materials and a polyethyleneimine ethoxylated (PEIE) thin layer as electron transport (ETLs) and injection layers (EILs), respectively.
