    Sammanfattning : The global market for photovoltaics (PV) has increased rapidly: during 2014, 44 times more was installed than in 2004, partly due to a price reduction of 60-70% during the same time period. Economic support schemes that were needed to make PV competitive on the electricity market have gradually decreased and self-consumption of PV electricity is becoming more interesting internationally from an economic perspective.

    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Organic photovoltaics (OPVs) is a rapidly growing low-cost PV technology sector that relies on multiple benefits of organic semiconductors viz. being environmental-friendly with a simplified processing/fabrication and tunable properties. LÄS MER

  7. 30. Light Trapping and Alternative Electrodes for Organic Photovoltaic Devices

    Författare :Kristofer Tvingstedt; Olle Inganäs; Peter Peumans; Linköpings universitet; []
    Nyckelord :Light trapping; Organic solar cells; Tandem cells; Polymer solar cells; Plastsolceller; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Organic materials, such as conjugated polymers, have emerged as a promising alternative for the production of inexpensive and flexible photovoltaic cells. As conjugated polymers are soluble, liquid based printing techniques enable production on large scale to a price much lower than that for inorganic based solar cells. LÄS MER
