Optimize Micro-Textures for Increased Light Extraction in Flexible, Curved Displays
Flexible electronics have been envisioned to change the way we interact with technology. Flexible circuit boards are already ubiquitous. These applications of flexible electronics are packaged away inside electrical gadgets and instruments and are therefore not visible to the end user. Nevertheless the development of this technology allowed for tighter packed and therefore smaller and still powerful devices. Curved displays are an application of flexible electronics where the user directly interacts with the shaped object and the technological advancement is directly tangible for the end user.
Numerical Optimization of Organic and Hybrid Multijunction and Tandem Solar Cells
We present a numerical optimization of organic and hybrid multijunction solar cell devices , using an integrated optoelectronic device simulation approach that captures the essential properties of the complex multilayer structures, such as, light scattering at both macroscopic and rough thin film textures, resonator effects in coherent stacks, and the impact of organic interface properties for the design of efficient recombination layers . The optimization capabilities of the numerical device simulation framework are illustrated in the examples of textured perovskite silicon and all organic tandem solar cells.
