Master's thesis Renewable Energy ENE500 - University of Agder 2018The work done in this thesis has been focused on the comparison of the power production in
the ideal single junction cell, intermediate band solar cell, the unconstrained tandem cell, and the
area de-coupled 2-terminal constrained tandem cell, using di erent band gaps. The efficiency and
production for each of the concepts have been calculated based mathematical framework previously
established, using temperature and irradiation data collected from Kjøita in Kristiansand, using
MatLab. The monthly and annual power production for each of the concepts has been calculated
and compared. It has been found that the intermediate band solar cell with a band gap optimized
for the Am1.5 spectrum, has an annual production 3.6% and 3% higher than the 2-terminal and
4-terminal double junction solar cells with band gaps optimized for Am1.5. Also, the intermediate
band solar, 2-terminal and 4-terminal double was shown to have an annual production 29%, 26.5%,
and 26.8% higher, respectively, than the single junction cell with Am1.5 optimized band gap
