  2. 21. Materials Modelling for Energy Harvesting : From Conversion to Application through Storage

    Author : Amitava Banerjee; Rajeev Ahuja; Gunnar Niklasson; Sudip Chakraborty; Tejs Vegge; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Materials Modelling; DFT; Energy Materials; Photocatalysis; HER and OER; Hybrid Perovskite Solar Cells; Stability; Thermodynamics and Kinetics in Na-ion battery; Organic Crystal Battery;

    Abstract : In this Ph.D. thesis, ab initio density functional theory along with molecular dynamics and global optimization methods are used to unveil and understand the structures and properties of energy relevant materials. In this connection, the following applications are considered: i. READ MORE

  4. 22. Combined solar and pellet heating systems for single-family houses : How to achieve decreased electricity usage, increased system efficiency and increased solar gains

    Author : Tomas Persson; Per Lundqvist; Simon Furbo; Högskolan Dalarna; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Pellet; pelleteldning; kamin; panna; solvärmesystem; varmvattenberedning; systemutformning; småhus; elbesparing; verkningsgrad; emissioner; rökgasförluster; skorstensförlust; diskmaskin; tvättmaskin; Thermal energy engineering;

    Abstract : In Sweden, there are about 0.5 million single-family houses that are heated by electricity alone, and rising electricity costs force the conversion to other heating sources such as heat pumps and wood pellet heating systems. Pellet heating systems for single-family houses are currently a strongly growing market. READ MORE
