1. ALD Buffer Layer Growth and Interface Formation on Cu(In,Ga)Se2 Solar Cell Absorbers
Abstract : Cu(In,Ga)Se2 (CIGS) thin film solar cells contain a thin layer of CdS. To avoid toxic heavy-metal-containing waste in the module production the development of a cadmium-free buffer layer is desirable. This thesis considers alternative Cd-free buffer materials deposited by Atomic Layer Deposition (ALD). READ MORE

2. Sputtering-based processes for thin film chalcogenide solar cells on steel substrates
Abstract : Thin film chalcogenide solar cells are promising photovoltaic technologies. Cu(In,Ga)Se2 (CIGS)-based devices are already produced at industrial scale and record laboratory efficiency surpasses 22 %. Cu2ZnSn(S,Se)4 (CZTS) is an alternative material that is based on earth-abundant elements. READ MORE

3. Green procurement of buildings: estimation of environmental impact and life-cycle cost
Abstract : This thesis focuses on environmental impact reduction and life-cycle cost estimations in building procurement. The aim for the work presented in this thesis is to contribute to the understanding of whether costs and environmental impact of a building can be integrated in a, from the users perspective, practical model applied for tender evaluation.
