Wave Optics Simulation of Subwavelength Structures within Solar Cells: Integration of RCWA with GenPro4

To further improve the light management and optical performance of solar cells, research into nano-textured interfaces has led to a need for a fast and accurate wave optics model. Currently, within the PVMD group at the TU Delft an optical solar cell simulation tool, GenPro4, is being developed to allow for the quick optimization and analysis of...

Influence of interspace and controlled disorder on bactericidal properties of nanopatterns

Patients with orthopaedic implants often experience implant-associated infections (IAI), one of the most prominent causes for implant failure. IAIs are caused by pathogens adhering to the implant surface. One method to prevent IAIs is through the use of surface topography modifications. Cellular behaviour has been shown to be influenced by...

Studying the nanostructure of a-Si:h solar cell absorber layers using positrion annihilation and neutron reflectometry

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...
