1. 16. Potential-Induced Degradation and possibilities for recovery of CuIn1-xGaxSe2 thin film solar cells

   Författare :Viktor Fjällström; Marika Edoff; Uwe Zimmermann; Thomas Walter; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Sammanfattning : The long-term performance of solar modules is of key importance to achieve profitable solar power installations. In this work, the degradation mechanism potential-induced degradation (PID) was investigated for CuIn1-xGaxSe2 (CIGS) thin film solar cells. LÄS MER

3. 17. On the Road to Graphene Biosensors

   Författare :Malkolm Hinnemo; Zhi-Bin Zhang; Shi-Li Zhang; Jörgen Olsson; Max Lemme; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Graphene; Biosensors; Microprocessing; Photolithography; Surface Physics; Raman Spectroscopy; Transistors; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Sammanfattning : Biosensors are devices that detect biological elements and then transmit a readable signal. Biosensors can automatize diagnostics that would otherwise have to be performed by a physician or perhaps not be possible to perform at all. Current biosensors are however either limited to particular diseases or prohibitively expensive. LÄS MER

4. 18. In the confines of Cu(In,Ga)Se2 thin film solar cells with rear surface passivating oxide layers

   Författare :Dorothea Ledinek; Marika Edoff; Charlotte Platzer Björkman; Jan Keller; Christian Kaufmann; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alkali; Alumina; Back contact; CIGS; CIGSe; Hafnia; Passivation; Rear contact; Sodium fluoride; Ultra-thin; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Sammanfattning : The material supply to build renewable energy conversion systems needs to be considered from both a cost and an energy security perspective. For Cu(In,Ga)Se2 (CIGS) thin film solar cells the use of indium in the absorber layer is most problematic. LÄS MER

5. 19. Reactive Sputter Deposition of Functional Thin Films

   Författare :Lina Liljeholm; Jörgen Olsson; Ilia Katardjiev; Tomas Nyberg; Gonzalo Fuentes Iriarte; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thin film; reactive sputtering; coating; resonator; sensor; FBAR; SMR; aluminum nitride; Al; B N; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Sammanfattning : Thin film technology is of great significance for a variety of products, such as electronics, anti-reflective or hard coatings, sensors, solar cells, etc. This thesis concerns the synthesis of thin functional films, reactive magnetron sputter deposition process as such and the physical and functional characterization of the thin films synthesized.

7. 20. Design and Characterization of RF-LDMOS Transistors and Si-on-SiC Hybrid Substrates

   Författare :Sara Lotfi; Jörgen Olsson; Örjan Vallin; Jean-Pierre Raskin; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LDMOS; RF; losses; crosstalk; silicon carbide; Si-on-SiC hybrid substrate; wafer bonding; CMOS; Teknisk fysik med inriktning mot elektronik; Engineering Science with specialization in Electronics;

   Sammanfattning : With increasing amount of user data and applications in wireless communication technology, demands are growing on performance and fabrication costs. One way to decrease cost is to integrate the building blocks in an RF system where digital blocks and high power amplifiers then are combined on one chip. LÄS MER
