Visar resultat 1 - 5 av 89 avhandlingar innehållade orden solar cell efficiency.
Sammanfattning : The energy demand of society increases rapidly, while the main source of today’s energy, the fossil fuels, eventually will be depleted and also poses environmental and climate hazards (though the global warming). Therefore there is a need for alternative, renewable energy sources, and solar photovoltaics (solar cells) will play an important role as one of them. LÄS MER
- Detta är en avhandling från Faculty of Engineering, LTH at Lund University
Sammanfattning : Solar electricity is one of the most promising technologies for our future electricity supply. By using concentrators, it is possible to reduce the cost of generating photovoltaic electricity. This thesis discusses how to design stationary low concentrating systems for photovoltaic or PV/Thermal applications. LÄS MER

Sammanfattning : The dye-sensitized solar cell (DSC) is a promising efficient low-cost molecular photovoltaic device. One of the key components in DSCs is the dye, as it is responsible for the capture of sunlight.State-of-the-art DSC devices, based on ruthenium dyes, show record efficiencies of 10-12 %. LÄS MER

Sammanfattning : The need for systems for renewable electrical power production is enormous worldwide.This applies to systems of varying size and capacity. From small systems for household purposes up to large systems for regional purposes. If possible, all systems should be linked in a common power grid. LÄS MER
5. Exploring Electron Transfer Dynamics of Novel Dye Sensitized Photocathodes Towards Solar Cells and Solar FuelsDetta är en avhandling från Uppsala : Acta Universitatis Upsaliensis
Sammanfattning : The design of dyes for NiO-based dye-sensitized solar cells (DSSCs) has drawn attention owing to their potential applications in photocatalysis and because they are indispensable for the development of tandem dye-sensitized solar cells. The understanding of the electron transfer mechanisms and dynamics is beneficial to guide further dye design and further improve the performance of photocathode in solar cells and solar fuel devices.
