1. 16. Evaluating the economic viability of Perovskite – SHJ monolithically integrated photovoltaic modules

   Master-uppsats, Uppsala universitet/Fasta tillståndets elektronik

   Författare :Marwyn Vernon; [2018]
   Nyckelord :solar energy; perovskite; economic viability; economics; LCOE; energy yield;

   Sammanfattning : In this study, the financial and economic viable of perovskite-SHJ tandem solar cells were determined using a detailed bottom-up cost model and energy-yield calculations. Attention to specific advancements in perovskite solar cell layer technology and large-scale deposition have been taken into account to create a realistic, viable commercial scale option for tandem production.

3. 17. Development and characterisation of silicon solar cells with recombination interconnects for future tandem solar cells

   Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

   Författare :Marika Gugole; [2018]
   Nyckelord :;

   Sammanfattning : In this project commercial BSF Si solar cells have been processed in order to develop a suitable interconnect for a possible tandem solar cell. The Ag original top contacts have been removed and replaced with TiSi2 formed using the SALICIDE process at 3 different temperatures: 500 °C, 650 °C and 750 °C. LÄS MER

4. 18. SnOx electron selective layers for perovskite/silicon tandem solar cells using atomic layer deposition

   Master-uppsats, KTH/Energiteknik

   Författare :Lisa Anna Zafoschnig; [2018]
   Nyckelord :;

   Sammanfattning : In this work the application of ALD deposited SnOx films as electron transport layers in perovskite solar cells is analysed. Processes to fabricate homogeneous, transparent and conductive tin oxide films were developed on an Oxford Instruments FlexAL tool using a TDMASn precursor and H2O as oxidiser. LÄS MER

5. 19. Silicon solar cells: basics of simulation and modelling : Using the mathematical program Maple to simulate and model a silicon solar cell

   Kandidat-uppsats, Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

   Författare :Sebastian Ekhagen; [2017]
   Nyckelord :solar cell; semiconductor; physics; condensed matter physics; solid state physics; applied physics; solcell; halvledare; fysik; material fysik; applicerad fysik; fasta tillståndets fysik.;

   Sammanfattning : The main goal of this thesis was to simulate a solar cell with the symbolic manipulation tool Maple and discuss the strength and weaknesses of using Maple instead of the already known simulation program PC1D. This was done mainly by solving the three essential differential equations governing the current density and excess electron and hole densities in the solar cell. LÄS MER

7. 20. Investigation of Bismuth Iodine as Light Absorbing Materials for Solar Cell Applications: From Synthesis to XPS Characterisation

   Master-uppsats, Uppsala universitet/Molekyl- och kondenserade materiens fysik

   Författare :Jonatan Fast; [2017]
   Nyckelord :Bismuth; Iodine; Light absorbing; Light absorbing materials; Solar; solar cell; Synthesis; XPS; Characterisation; synchrotron; energy; x-ray photoelectron spectroscopy; perovskite;

   Sammanfattning : During the last years perovskite materials have taken the photovoltaic community by storm, bringing promises of solar cells with efficiencies comparable to conventional silicon devices but at a lower price. However perovskite solar cells so far are facing two main obstacles, they are unstable in the presence of air, moisture and heat and they are usually toxic due to being based on lead-halide materials.
