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. Correlated Structure-Property Investigation of Ultrathin InAs Nanowires

   Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Författare :Linnea Suomenniemi; [2019]
   Nyckelord :Nanowires; InAs; epitaxy; MBE; Photo luminescence; Physics and Astronomy;

   Sammanfattning : III-V semiconductors are a profound part of the optoelectronics industry and new developments in alloy compositions and architectures are constantly emerging. Lowdimensional semiconductors, such as nanowires (NWs) have shown to have improved characteristics in certain areas such as enhanced light absorption and can furthermore be integrated on Silicon (Si) plattforms and are thus predicted to be a key component in future nanoelectronic and nanophotonic applications and devices.

4. 3. Additive Manufacturing of Silicon Nitride

   Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Materialvetenskap

   Författare :Céline Montanari; [2017]
   Nyckelord :ceramics; silicon nitride; additive manufacturing; stereolithography; photopolymerization;

   Sammanfattning : This study aims to investigate the fabrication of silicon nitride ceramics via additive manufacturing method. Silicon nitride exhibits excellent thermo-mechanical properties and it is one of the main structural ceramics. The excellent properties of silicon nitride are obtained through densification via liquid phase sintering. LÄS MER

5. 4. Fabrication and characterization of nano/micrometer glass channels with UV lithography

   Magister-uppsats, Uppsala universitet/Mikrosystemteknik; Uppsala universitet/Institutionen för cell- och molekylärbiologi; Uppsala universitet/Institutionen för biologisk grundutbildning

   Författare :Krishna Narayan; [2017]
   Nyckelord :Microtechnology; Biotechnology; Nanotechnology;

   Sammanfattning : In this project, fabrication and characterization of nano/microfluidic channels on borosilicate glass substrate were carried out using a Photo/Ultraviolet (UV) lithography method, which has applications in single-cell analysis. In our single-cell analysis glass system, the bacterial cells will be made to sit in the micrometer channels and also the sub-micron size channels around 300 nm is aspired so it helps in passing the fluid to the outlet hole while holding the cells back.

7. 5. 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.
