Quenching Mo optical losses in CIGS solar cells by a point contacted dual-layer dielectric spacer: a 3-D optical study
A 3-D optical modelling was calibrated to calculate the light absorption and the total reflection of fabricated CIGS solar cells. Absorption losses at molybdenum (Mo) / CIGS interface were explained in terms of plasmonic waves. To quench these losses, we assumed the insertion of a lossless dielectric spacer between Mo and CIGS, whose optical properties […]
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 […]
