1. 16. Development and characterisation of silicon solar cells with recombination interconnects for future tandem solar cells

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Marika Gugole; [2018]
   Keywords : ;

   Abstract : 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. READ MORE

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

   University essay from KTH/Energiteknik

   Author : Lisa Anna Zafoschnig; [2018]
   Keywords : ;

   Abstract : 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. READ MORE

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

   University essay from Karlstads universitet/Fakulteten för hälsa, natur- och teknikvetenskap (from 2013)

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

   Abstract : 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. READ MORE

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

   University essay from Uppsala universitet/Molekyl- och kondenserade materiens fysik

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

   Abstract : 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.

6. 20. Role of annealing and photostability of organo-metal-halide semiconductors for solar cell applications

   University essay from Lunds universitet/Centrum för analys och syntes

   Author : David Sörell Jonsson; [2016]
   Keywords : materials chemistry; materialkemi; Chemistry;

   Abstract : Methyl ammonium lead halides (MAPbX3 , X=Cl-, Br-,I-), crystallizing in a perovskite structure, have in recent years been shown to be a promising material as a light harvesting material in solar cells. It has many interesting properties which makes it suitable for solar cell applications, such as near-optimal band gap and long electron-hole diffusion lengths, as well as the possibility of synthesizing the films from solution based methods.
