Abstract

The issue of climate change, including global warming, poses a significant challenge to our planet. In response to this challenge, the Paris Agreement was signed, which aims to limit the rise in global temperatures to well below 2 ◦C and pursue efforts to limit it even further to 1.5 ◦C. Photovoltaic energy is the key to achieving this target.
This dissertation focuses on improving the efficiency and sustainability of interdigitated back contact (IBC) solar cells. A special emphasis is also placed on cost and reliability. IBC cells and modules utilized in this study are based on ZEBRA technologies, which were developed at ISC Konstanz and implemented using processes and equipment that are comparable to those employed in conventional solar cells, such as Al-BSF and PERC. A detailed discussion of the process and history can be found in Chapter 2...
