Sammanfattning : Increasing energy consumption and its environmental impacts make it necessary to look for alternative energy sources. Solar energy as huge energy source which is able to cover the terms sustainability is considered as a favorable alternative. LÄS MER
23. Environmental Assessment of Battery Systems: Critical Issues for Established and Emerging Technologies
Sammanfattning : Energy and material flows associated with portable and industrial rechargeable batteries have been quantified in a life-cycle perspective, as guidance for development of battery systems. The study included portable batteries based on nickel-cadmium, nickel-metal hydride and lithium-ion. LÄS MER
24. Low Band-Gap Conjugated Polymers for Plastic Solar Cells
Sammanfattning : Today, fossil fuels like coal, oil, and natural gas are used for more than 60% of the world's electricity production. These fuels have a very negative impact on the environment and many researchers agree that the earth's climate is changing as a consequence of fossil fuel emissions. LÄS MER
25. Liquid Redox Electrolytes for Dye-Sensitized Solar Cells
Sammanfattning : This thesis focuses on liquid redox electrolytes in dye-sensitized solar cells (DSCs). A liquid redox electrolyte, as one of the key constituents in DSCs, typically consists of a redox mediator, additives and a solvent. LÄS MER
