  1. 1. Robust TCO’s for CIGS solar cells based on indium tin oxide

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Julia Nilsson; [2022]
    Keywords : photovoltaics; solar cells; thin film photovoltaics; PV; TCO; transparent conductive oxide; indium tin oxide; ITO; CIGS; solar power; sputtering; RF sputtering; radio frequency sputtering;

    Abstract : The increasing energy demand, combined with the use of harmful non-renewable energy sources calls for the search of alternative methods to cover our energy need.Renewable energy can be harvested in different ways, through the movement of wind and water, biomass, or directly from the rays of the sun, as in the case of photovoltaic (PV) devices.

  3. 2. 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.

  4. 3. Study of HfN as seed layer for next generation of BAW RF filters : synthesis, characterization, and investigation of piezoelectric performance

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Eduard Llorens Balada; [2020]
    Keywords : HfN; AlScN; AlN; sputtering; XRD; SEM; seed layer; epitaxial growth;

    Abstract : Micro-electro-mechanical systems (MEMS) have become an essential component of a wide range ofelectronic devices over the last decades such as accelerometers, microphones, gas sensors, and filters.During this new millennium, a new radio frequency (RF) technology has been developed to satisfy thetough demands that arose due to the implementation of 5G wireless communication: bulk acoustic wave(BAW) filters.

  5. 4. Cu2O/TiO2 Nanorod Heterojunctions: Synthesis, Characterization and Applications as Solar Cells on the Nanoscale

    University essay from Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Author : Edward Dellamary; [2020]
    Keywords : ;

    Abstract : Novel solar cells are being synthesized from sustainable, non-toxic, and economic materials. All metal oxide semiconductors are one such class of these materials. READ MORE

  6. 5. Transparent conductive oxides deposited by magnetron sputtering: synthesis and characterization

    University essay from Uppsala universitet/Fasta tillståndets elektronik

    Author : Mathias Axelsson; [2019]
    Keywords : TCO; AZO; solar cell; magnetron sputtering;

    Abstract : The thesis has dealt with transparent conducting oxide (TCO) materials, with a focus on Al:ZnO and with studies on Sn:In2O3 and ZnO. TCOs are a material group that is used for its properties of being conductive and at the same time transparent. READ MORE
