2. 1. Functional Metal Oxide Materials Deposited by Inkjet Printing Technique

   Author : Yan Wu; Lyubov Belova; Gillian Gehring; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Inkjet printing; photoconductivity; ZnO; Al-ZnO; composite; electron transfer; CdS; field effect transistor; photosensitive; RT do-ferromagnetism; Mn-doped ZnO; MgO; Materials science; Teknisk materialvetenskap;

   Abstract : This thesis presents a comprehensive study of the intrinsic room temperature ferromagnetism in 85 to 100nm thin films produced by in situ deposition of industrially important pristine MgO and ZnO by inkjet printing. It is suggested that the observed long range magnetic order, the so-called do magnetism in these oxides arises from cation vacancies. READ MORE

4. 2. Integration of Battery and Hydrogen Storage with a Grid-Connected Photovoltaic System in Buildings

   Author : Yang Zhang; Jinyue Yan; Jianzhong Wu; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Photovoltaic; Grid; Building; Battery; Hydrogen Storage; Operation Strategy; Optimization; Energiteknik; Energy Technology;

   Abstract :     The integration of Photovoltaic (PV) with buildings changes the previous electricity consumers into prosumers. The reduced PV subsidies and the grid stable operation requirements are pushing prosumers from direct exportation to self-consumption of the produced electricity. READ MORE
