  1. 1. Processing of Sub-micrometer Features for Rear Contact Passivation Layer of Ultrathin Film Solar Cells Using Optical Lithography

    Kandidat-uppsats,

    Författare :Evelina Roxner; Ronja Olsmats Baumeister; [2019]
    Nyckelord :nanofabrication; optical lithography; photo lithography; line contacts; microfabrication; rear contact passivation; passivation layer; sub-micrometer features; thin film; ultra-thin film; solar cells; CIGS; aluminiumoxide;

    Sammanfattning : Thin film copper, indium, gallium, selenide (CIGS) solar cells are promising in the field of photovoltaic technology. To reduce material and fabrication cost, as well as increasing electrical properties of the cell, research is ongoing towards ultra-thin film solar cells (absorption layer thickness less than 500 nm).

  3. 2. 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

  4. 3. Influence of Na doping on tunnelling rear contact passivation in Cu(In,Ga)Se2 solar cells

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fasta tillståndets elektronik

    Författare :Markus Sköld; [2016]
    Nyckelord :Sodium; Na; CIGS; solar cells; Passivation; rear contact; Al2O3; tunnelling; tunneling;

    Sammanfattning : In this thesis Cu(In,Ga)Se2 (CIGS) solar cells with different sodiumdoping of the CIGS absorber and varying Al2O3 rear surface passivationlayer thickness have been manufactured and electrically characterised. Baseline samples and samples without passivation were used asreferences for the passivated samples. LÄS MER

  5. 4. Rear side BSF/emitter patterning of SHJ-IBC solar cells using selective deposition and hydrogen plasma etching of a-Si:H

    Master-uppsats, KTH/Skolan för informations- och kommunikationsteknik (ICT)

    Författare :Mahmudul Hasan; [2016]
    Nyckelord :;

    Sammanfattning : Silicon heterojunction interdigitated back-contact (SHJ-IBC) solar cells have attracted considerable attention because of their potential to achieve very highly efficiency. However, the back contacting scheme leads to additional fabrication complexity mainly resulting from the formation of interdigitated n- (back surface field (BSF)) and p-type (emitter) hydrogenated amorphous silicon (aSi:H) strips.
