21. Comparison of the performance of silicon and thin film solar cells at the laboratory of the University of Gävle
University essay from Högskolan i Gävle/Avdelningen för bygg- energi- och miljöteknikAbstract : The huge environmental awareness emerging last years by reason of global warming and greenhouse effect, on one hand, and the need of finding other sources of energy production and conversion due to the declining of fossil resources and the increasing cost of this kind of energy resource, on the other hand, both have led position renewable energies as a powerful alternative on the energy production and conversion. PV-systems have emerged at an exponential rate in recent year as the main candidate and a satisfactory possibility with respect to environmental and economic sustainability. READ MORE

22. Influence of Na doping on tunnelling rear contact passivation in Cu(In,Ga)Se2 solar cells
University essay from Uppsala universitet/Fasta tillståndets elektronikAbstract : 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. READ MORE

23. Gas flow sputtering of Cu(In,Ga)Se2 with extra selenium supply
University essay from Uppsala universitet/Fasta tillståndets elektronikAbstract : In this thesis CIGS absorber layers have been deposited by gas flow sputtering with an extra supply of selenium, a method that displays promise for large scale production because of its one-step sputtering route which deposits low energy particles in a high deposition rate. In this thesis a method was developed where selenium was added to the sputtering process inside the sputter chamber in a controllable manner and in larger amount than done in previous projects.

24. Evaluation of a PVT Air Collector
University essay from Högskolan Dalarna/ElektroteknikAbstract : Hybrid Photovoltaic Thermal (PVT) collectors are an emerging technology that combines PV and solar thermal systems in a single solar collector producing heat and electricity simultaneously. The focus of this thesis work is to evaluate the performance of unglazed open loop PVT air system integrated on a garage roof in Borlänge. READ MORE

25. Cu-tråd som elektrisk ledare i CIGS-tunnfilmssolceller för att sänka silvermängden utan att förlora verkningsgrad
University essay from KTH/Skolan för informations- och kommunikationsteknik (ICT)Abstract : The solar industry is bigger than ever and continues to grow while competition between the solar cell manufacturers is increasing. This is something that has lowered the prices of solar cells and reduces the profitability for manufacturers. READ MORE
