In order to accelerate the development of photovoltaic energy conversion as a major source of renewable energy in the global energy mix, manufacturing of solar cells with increasing efficiency is a powerful means of cost reduction. Interdigitated back contact (IBC) solar cells currently have the hig...
The driving force in photovoltaics is the reduction of the ratio between device costs and conversion efficiency. The present research study introduces a highly innovative diffusion process, called co-diffusion, which allows for a drastic decrease in process costs, on the one hand, and the assembly o...
In this work, a high-efficiency back-contact back-junction (BC-BJ) silicon solar cell was developed and characterized that features an aluminum-alloyed emitter and industrially feasible process steps like screen-printing used for structuring and metallization. The aim was to develop a solar cell pro...
Das Ziel der vorliegenden Dissertation ist die Untersuchung der Langzeitstabilität von CIGS-Dünnschichtsolarzellen. Basis der Untersuchungen sind beschleunigte Alterungstests. Eine elementare Erkenntnis der beschleunigten Alterungstests war, dass das Verhalten bei tiefen Temperaturen im Ausgangszu...
The standard method to extract the recombination parameter J0 and the carrier lifetime in the base substrate from lifetime measurements of samples exhibiting diffused surfaces is revised, adapted, and tested on simulation and measurement data sets.
An analytical model for solar cells with locally c...
The use of lightweight structures across several industries has become inevitable in today’s world given the ever-rising demand for improved fuel economy and resource efficiency. In the automotive industry, composites, reinforced plastics, and lightweight materials, such as aluminum and magnesium ...
