Oludare Oyediran, D. (author)The plasma-enhanced chemical vapour deposition (PECVD) method is widely used compared to other methods to deposit µc-Si:H because of the high potential to prepare high quality material uniformily on a large area substrate at low temperature. This method was used to grow µc-Si:H p- and i-layers. The effect of p– layer deposition parameters on the...master thesis 2009

Nebo, C.U. (author)In recent times, thin-film solar cells have gained a lot of attention. This can be attributed to the low material cost as well as its low energy consumption. The micromorph solar cell configuration consisting of a top amorphous silicon cell and a bottom microcrystalline silicon cell has proved to be one of the promising approaches in thin-film...master thesis 2009

Wiegman, J.W.E. (author)Nowadays silicon solar cells are widely used to produce electric energy. However, considering its efficiency, there is room for improvement. The solar spectrum ranges from 300 nm to 2,500 nm, whereas the band gap of the silicon solar cell converts only a small band around 1,000 nm at full efficiency into electricity. The spectrum below the band...bachelor thesis 2010

Sap, J.A. (author)In the research on solar cells, accurate characterization techniques are of great importance. In this work a specific technique is studied that makes use of transmitted and reflected light from a thin layer. The material properties of transparent conductive oxides (TCOs), silicon and nanoparticles are extracted by fitting a mathematical model on...master thesis 2010

Bolman, B.F.A. (author)Within thin-film silicon solar cells, the so-called Transparent Conductive Oxide (TCO) plays an important role. The optimization of TCOs is a very meticulous process since these thin layers not only need to be both highly transparent and conductive, but are also used for light management; that is manipulating the path of the light through the...master thesis 2010

Bensdorp, S. (author)In this thesis we perform a in-depth comparison study between different geometri- cal possibilities for solar cells to find an optimal design. Basic numerical experiments on the essential parts of the improve- ments in the geometry were performed separately to obtain an indication about increasing efficiency for 2D configurations. Our research...master thesis 2011

Blanker, A.J. (author)In the field of thin film solar cells light management is an important mechanism to improve efficiency. Manipulating the reflectivity and distribution of scattering angles significantly contribute to absorbing light with relative long wavelengths. In this thesis the scattering effect of titaniumdioxide nanoparticles (0.2-0.3 micron) for the use...master thesis 2013

Rutten, J. (author)Thanks to advances in technology a time has arrived where it is possible to generate energy by virtually everyone for a competitive price. To produce energy on a small scale, fossil fuels are unattractive because energy can be extracted from them more efficiently on a larger scale. For technologies such as solar photovoltaic panels, there is no...master thesis 2013

Mannheim, A. (author)Hydrogenated Amorphous Silicon (a-Si:H) is a very promising solar cell material with a good potential to use in many applications, as it is cheap to produce, light-weight and flexible. However, upon prolonged exposure to light, the layers suffer from both metastable and irreversible changes (the Staebler-Wronski effect) that have a bad effect on...master thesis 2013

Harihara Subramanian, K.K. (author)The commercial efficiency of a c-Si solar cell is ~18% although the thermodynamic limit is ~95%. This indicates a good scope for improvements. The major loss mechanism in a solar cell is spectral mismatch which is contributed to by non-absorption of low energy photons and thermalization of high energy photons. In this thesis, it is sought to...master thesis 2013
