Advanced light management techniques for two-terminal hybrid tandem solar cells

Multi-junction solar cells are considered for various applications, as they tackle various loss mechanisms for single junction solar cells. These losses include thermalization and non-absorption below the band gap. In this work, a tandem configuration comprising copper-indium-gallium-di-selenide (CIGS) and hydrogenated amorphous silicon (a-Si:H) absorber layers is studied. Two main challenges are addressed in this work. […]

Are energy decisions about energy?

Research shows that buildings should use 80% less energy in 2050 to counter climate change and to reduce dependence on fossil fuels [1, 2]. To achieve this in the Netherlands, 75% of the Dutch houses should be renovated [3] with a pace of 300,000 houses each year [2]. This can be achieved by one-off energy […]
