    Sammanfattning : “Heat is half” of the global final energy consumption, and the decarbonization of the heating sector is critical to achieving climate goals. This thesis employs a system modelling approach to evaluate renewable heating systems. LÄS MER

  4. 28. Solar access indicators for urban planning

    Författare :Agnieszka Czachura; Avdelningen för Energi och byggnadsdesign; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; solar access; urban planning; performance indicator; daylighting; sunlighting; neighbourhood; metric taxonomy; urban density;

    Sammanfattning : Solar access describes the amount and distribution of sunlight in living environments. Access to sunlight is crucial for the health and sustainability of cities. It is vital for people and vegetation, and for energy production and conservation. LÄS MER

  5. 29. Quantum Dot Solar Cells: Towards Environmentally Friendly Materials

    Författare :Viktor A. Öberg; Erik Johansson; Muhammet S. Toprak; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Quantum dots; Nano-crystals; Energy conversion; Solar cells; Quantum dot solar cells; Low toxicity; Silver Sulfide; Silver Bismuth Sulfide; Lead Sulfide; Chemistry with specialization in Physical Chemistry; Kemi med inriktning mot fysikalisk kemi;

    Sammanfattning : To decrease the world’s energy dependence on fossil fuels, energy production and specifically electricity production needs to shift to more sustainable alternatives. One such alternative is solar cells as they directly convert energy emitted from the sun into electricity. LÄS MER
