1. 1. Synthesis of Organo-Iron(II) Complexes Including N-Heterocyclic Carbene Ligation as Solar Cell Material.

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : Salim Charkas; [2023]
   Keywords : Dye-sensitized solar cell; Transition metal complex; Synthesis iron; N-heterocyclic carbene NHC ; Organic chemistry; Chemistry;

   Abstract : The push-pull design has been shown to increase DSC performance through the introduction of electron-withdrawing groups and electron-donating groups, usually on opposite far ends of the sensitizer. The scope of this thesis was to synthesize several pre-N-heterocyclic carbene ligand analogs that are inspired by the push-pull design in an attempt to investigate their susceptibility to Fe(II) complexation.

3. 2. Energy audit of a single-family house in a city in the middle of Sweden

   University essay from Högskolan i Gävle/Energisystem och byggnadsteknik

   Author : Daniela Valentina García Gimeno; [2023]
   Keywords : energy audit; building energy efficiency; building envelope; renewable sources; windows efficiency; insulation of houses in Sweden;

   Abstract : The world is currently submerged in two big problems: supply energy crisis and climate change. It is clear that society has to do its best to overcome these challenges, and one effective way to mitigate their effects is by conducting an energy audit, which helps to identify the weaknesses and strengths of the buildings, enabling improvements in their thermal efficiency.

4. 3. Tuning Photovoltaic Properties of Two-dimensional Molybdenum Disulfide by Alloying: An ab initio study

   University essay from KTH/Materialvetenskap

   Author : Mochen Li; [2023]
   Keywords : Photovoltaic; Molybdenum disulfide; Absorption coefficient; ab initio material design; Fotovoltaisk; Molybdendisulfid; Absorptionskoefficient; ab initio materialdesign;

   Abstract : Addressing the urgent need for innovative energy solutions amidst increasing environmental concerns, the focus on photovoltaic solar cells is intensifying. Currently limited by the Shockley-Queisser limit, conventional silicon-based solar cells offer a maximum power conversion efficiency of 32%. READ MORE

5. 4. Fabrication and characterization of GaAsxP1-x single junction solar cell on Si for III-V/Si tandem solar cell

   University essay from KTH/Tillämpad fysik

   Author : Elaheh Aghajafari; [2023]
   Keywords : III-V semiconductor; GaAsxP1-x heteroeputaxy; hydride vapor phase epitaxy; III-V Si solar cell; III-V halvledare; GaAsxP1-x epitaxiallager; hydridångfasepitaxi; III-V Si solcell;

   Abstract : Silicon based solar cells have been used as photovoltaic devices for decades due to reasonable cost and environment- friendly nature of silicon. But the conversion efficiency of silicon solar cell is limited; for instance, the maximum conversion efficiency of a crystalline silicon solar cell available in the market developed by Kaneka Corporation is 26 % [1].

6. 5. Comparison of the lead-leakage in Pb-Sn hybrid perovskite solar cells and Pb-based perovskite solar cells

   University essay from Linköpings universitet/Tema Miljöförändring

   Author : Chao Cui; [2023]
   Keywords : perovskite; solar cell; Pb-Sn hybrid; lead leakage;

   Abstract : Perovskite solar cells exhibit outstanding device performance and photovoltaic potential in recent ten years. However, the photoactive layer of the majority of perovskite solar cells with outstanding efficiency currently contains toxic lead. READ MORE
