    Sammanfattning : Grid-connected photovoltaic (PV) capacity is increasing worldwide, mainly due to extensive subsidy schemes for renewable electricity generation. A majority of newly installed systems are distributed small-scale systems located in distribution grids, often at residential customers. LÄS MER

  5. 9. On Generation and Recombination in Cu(In,Ga)Se2 Thin-Film Solar Cells

    Författare :Jonas Malmström; Lars Stolt; Uwe Rau; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; solar energy conversion; solar cells; Cu In; Ga Se2; device modelling; optical properties; electron-hole generation; light trapping; electron-hole recombination; Elektronik; Electronics; Elektronik;

    Sammanfattning : The solar cell technology based on Cu(In,Ga)Se2 (CIGS) thin-films provides a promising route to cost competitive solar electricity. The standard device structure is ZnO:Al/ZnO/CdS/CIGS/Mo films on a glass substrate, where the first three layers are n-type semiconductors with wide bandgaps, forming a pn-junction with the p-type CIGS absorber layer; the Mo layer serves as a back contact.

  7. 10. Solar Variability Assessment and Grid Integration : Methodology Development and Case Studies

    Författare :David Lingfors; Joakim Widén; Uwe Zimmermann; Eva Wäckelgård; Tobias Boström; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solar variability; Photovoltaics; Grid integration; GIS; Distributed generation; Engineering Science; Teknisk fysik;

    Sammanfattning : During the 21st century there has been a tremendous increase in grid-connected photovoltaic (PV) capacity globally, due to falling prices and introduction of economic incentives. PV systems are in most cases small-scale, installed on residential dwellings, which means that the power production is widely distributed and close to the end-user of electricity. LÄS MER
