Defektspektroskopie an Solarzellen und Schottky-Kontakten auf Basis des Halbleiters Cu(In,Ga)Se 2
Solarzellen auf Basis des Halbleiters Cu(In,Ga)Se2 (CIGS) sind dabei, die Grenze zur Kommerzialisierung zu überschreiten. Ein Spitzenwirkungsgrad von bisher knapp 19% verspricht ein großes Potential. Leider hinkt das physikalische Verständnis den technologischen Erfolgen hinterher. In der …

Cu2ZnSn(S,Se)4 photovoltaic absorber fabrication by hydride chalcogenization of electrodeposited precursors
… related to the commercially available Cu(In,Ga)Se2 (CIGS) absorber material, CZTSSe consists of more readily-available materials, and may therefore offer cost reduction and highly scalable production potential if its PV properties can be controlled and improved. This work presents a two-step …

Optical characterization of copper indium gallium diselenide thin films
Cu(In,Ga)Se2 (CIGS) and its alloys are the leading choice for thin film photovoltaic absorber layers due to their high performance in devices, low degradation, high optical absorption coefficient and high tolerance to off-stoichiometry and intrinsic defects. Film conductivity and recombination …

Growth and characterization of epitaxial silver indium diselenide
… solar cell absorber material to date is Cu(In,Ga)Se2 (CIGS). While current efficiency records are over 21% for single-junction cells, there is still room for improvement. Replacing some of the Cu with Ag has been shown to be beneficial in CIGS devices. However, the Ag- containing chalcopyrites …

How visual representations affect undergraduate students’ use and understanding of engineering concepts during problem solving
In this two-part thesis, I address gaps in the surface science of semiconductor materials for photovoltaics and discipline-based education research literature. Surface Science of Semiconductor Materials for Photovoltaics With the rise of global energy consumption, it is important to find low-cost, …

Optical Modeling of Solar Cells
… layers and tandem cells. Experimentally investigating these combinations to optimize cell performance is expensive and time consuming. Computer simulations of the optical and electrical functions allow for eliminating large class of ineffective combinations and containing the parameter space …
