3. Advanced rear contact design for CIGS solar cells
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : 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. READ MORE

4. Detection of stator interturn fault of synchronous machine by rotor current analysis : A SIMULATION APPROACH
University essay from KTH/Skolan för elektro- och systemteknik (EES)Abstract : One of the major electrical faults of synchronous machines is an interturn short circuit in the stator winding, due to winding insulation failure. A synchronous machine is designed to have electrical and mechanical symmetry in the stator and rotor. READ MORE

5. Study of CVD deposited i-ZnO layers in CIGS thin film solar cells
University essay from Uppsala universitet/Fasta tillståndets elektronikAbstract : CIGS thin film solar cells usually include a thin layer of intrinsic zinc oxide (i-ZnO) deposited on a CdS buffer layer by sputtering. However an interest has grown in using chemical vapor deposition (CVD) instead. READ MORE
