  6. 4. In situ electron microscopy of strain-induced effects on electrical and photovoltaic properties of GaAs nanowires - site specific and quantitative studies

    Author : Jonatan Holmér; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; In situ electron microscopy; Solar cells; Elastic strain engineering; Semiconductor nanowires;

    Abstract : Semiconductor nanowires have different physical properties than their bulk counterparts due to their small physical dimensions and high surface-to-volume ratio. The nanowire geometry entails enhanced optical absorption, widened possibilities to grow material heterostructures and ability to withstand high levels of strain. READ MORE

  7. 5. Single Junction and Tandem Junction Nanowire Solar Cells

    Author : David Alcer; NanoLund: Centre for Nanoscience; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Nanowire solar cell; GaInP; InP; Tandem junction; Vertical processing;

    Abstract : Solar cells based on silicon are successfully harvesting solar energy in established and increasingly widespread solar panels. However, their efficiency is limited by the Shockley–Queisser limit. For certain applications where high efficiency is the key figure of merit, the use of multi-junction solar cells is desirable.
