Generation of electricity using renewable energy sources is becoming an integral part of the electrical energy mix. A substantial fraction of the electrical energy is foreseen to be generated by photovoltaic (PV) solar cells that directly convert light into electricity. Large scale application of building integrated PV is envisaged to aid the...

The current energy scenario requires not only the conversion of renewable energy sources into electrical energy, but also a way to store it to match the demand and supply. In particular, solar energy can be used to stabilize energy conversion and energy supply by converting the energy in other diverse ways. And important possibility are photo...

The direct utilization of sunlight is a critical energy source in a sustainable future. One of the options is to convert the solar energy into electricity using thin-film silicon-based solar cells (TFSSCs). Solar cells in a triple-junction configuration have exhibited the highest energy conversion efficiencies within the thin-film silicon...

Silicon heterojunction solar cells (SHJ) are currently one of the most promising solar cell technologies in the world. The SHJ solar cell is based on a crystalline silicon (c-Si) wafer, passivated on both sides with a thin intrinsic hydrogenated amorphous silicon (a-Si:H) layer. Subsequently, p-type and n-type doped layers are deposited on the...

Climate changes due to increase of CO2 emission are becoming a serious issue for this planet. The so called climate crisis has been the main topic of the last United Nations Climate Change Conference (COP 21) . Direct conversion of sunlight into electricity is one of the most promising technology for achieving the COP 21 agreement. Wafer-based...

Thin film CIGS solar cells and individual layers within these solar cells have been tested in order to assess their long term stability. Alongside with the execution of standard tests, in which elevated temperatures and humidity levels are used, the solar cells have also been exposed to a combination of elevated temperature and humidity and...

In this thesis we present results of the development of n-i-p thin-film silicon solar cells on randomly textured substrates, aiming for highly efficient micromorph solar cells (i.e., solar cells based on a ?c-Si:H bottom cell and a-Si:H top cell). For the efficiency of n-i-p thin-film silicon solar cells the interfaces between different layers...

Since the first report on the fabrication of hydrogenated amorphous silicon (a-Si:H) in 1965, this material has found many applications, for instance in the fabrication of solar cells, sensors and transistors. An especially notable example in the context of this thesis is thin-film silicon solar cells, which have attracted a lot of attention....

It has been predicted that due to the population growth the energy demand is increasing faster and faster. It has been well recognized that depleting fossil-fuel resources will not fulfill the energy need of the future world. Not to mention the problem of global warming caused by its combustion, and of energy security as a result of geopolitical...

In summary, this thesis shows the development and nanostructure analysis of doped silicon oxide layers. These layers are applied in thin-film silicon single and double junction solar cells. Concepts of intermediate reflectors (IR), consisting of silicon and/or zinc oxide, are applied in tandem cells. Multi-stack Bragg reflector IRs are tested in...

Due increasing energy use per capita and increasing world population, the world faces an energy-crisis. However, the energy required to solve it is abundantly available: solar energy. The technology to convert this energy to electricity, solar cell technology, is well-developed. The technical issue is how to manufacture solar cells at such a...

Building-integrated photovoltaic systems (BIPV) are able to improve the energy balance of buildings. However, this improvement can be analyzed quantitatively only if the electricity yield generated by the BIPV system is calculated. This PhD thesis presents a simulation program that calculates the electricity yield generated by BIPV systems,...

Solar energy can fulfil mankind’s energy needs and secure a more balanced distribution of primary sources of energy. Wafer-based and thin-film silicon solar cells dominate todays’ photovoltaic market because silicon is a non-toxic and abundant material and high conversion efficiencies are achieved with silicon-based solar cells. To stay...

Nano-textured interfaces between two media of different refractive indices scatter light. The angular distribution and the intensity of the scattered light are deter- mined by the geometry of the nano-textures and the difference of the refractive indices of the two media. Thin-film silicon solar cells (TFSSC), which convert sunlight directly...

The need for electrical energy is growing fast as a result of the expanding world population and economic activities. On top of this the energy need of each individual is also growing. At present the growth in energy demand is not matched by the growth in energy generation because of insufficient energy production. This energy gap therefore...
