  1. 6. Sputtered Transparent Contact Layers for Bifacial and Tandem Solar Cells

    University essay from Uppsala universitet/Solcellsteknik

    Author : Klara Kiselman; [2022]
    Keywords : Solar cells; ITO; indium doped tin oxide; bifacial cell; tandem cell; transparent conductive oxides;

    Abstract : A key to solar cells with lower environmental impact is higher efficiency and reduced material usages. Bifacial solar cells may have a higher efficiency as light can enter from two directions and tandem solar cells may use a larger part of the incoming solar spectrum, increasing the efficiency.

  3. 7. Design of LED setup for measuring tandem solar cell subcell J-V behaviour

    University essay from

    Author : Kristina Bergström; Mohammed Nour Kamalmaz; Erik Lindvall; [2022]
    Keywords : Tandem solar cell; LED; background light; bias; arduino; processing; subcell;

    Abstract : The need to accurately measure multi-junction (MJ) tandem solar cells' subcell current-voltage characteristics is increasing due to the vital information they provide about the efficiency, stability, and longevity of the cells. These measurements are rather difficult compared to their counterpart single-layer solar cell measurements. READ MORE

  4. 8. Film formation of mixed-halide perovskites for PSCs

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Lina Ekstedt; [2021]
    Keywords : Mixed Halide Perovskites; Perovskite Solar Cells; Bandgap Tuning; In-situ Spectroscopy; Antisolvent; Interface Modifier.; Physics and Astronomy;

    Abstract : Over the last few years there has been a steady increase in interest in the exploration of perovskite materials within photovoltaic research. This can to a large extent be attributed to the incredible pace at which solar cells based on perovskites have improved in efficiency during the same time period. READ MORE

  5. 9. Intermediate layer contacts for tandem solar cells based on ALD SnO2

    University essay from Uppsala universitet/Institutionen för fysik och astronomi

    Author : Georgia Iona; [2021]
    Keywords : Ald; SnO2; tandem cell; solar cell; IML; intermediate layer;

    Abstract : In this project, samples with a metal/semiconductor/metal structure were fabricated and investigated with the potential application as the interconnecting layer of a tandem solar cell in mind. Degenerately doped p-Si and n-Si were used as bottom (metal like) contacts, as Si represents one of the most common materials for the bottom cell of tandem devices. READ MORE

  6. 10. Magnetron sputtering of highly transparent p-conductive NiO thin films

    University essay from Uppsala universitet/Solcellsteknik

    Author : Martin Book; [2020]
    Keywords : Nickel oxide; Magnetron sputtering; Electrochromic; Transmittance; Absorption; Resistivity;

    Abstract : P-type transparent conductors are needed for a wide range of applicationssuch as solar cells and electrochromic smart windows. Solar power is animportant form of energy in today’s society as the threat of global warmingpushes the world towards fossil free energy. READ MORE
