    Tests of a diamond field-assisted positron moderator by Al-Qaradawi, I. Y.

    Published 2002
    “…A potential difference of up to 300 V could be held across the film with a leakage current of ∼ 10 nA. Although positron re-emission was observed from the diamond surface, the re-emitted fraction was observed to decrease when a bias of 300 V was applied across the film. …”

    Towards understanding the effects of climatic and environmental factors on solar PV performance in arid desert regions (Qatar) for various PV technologies by Touati F.

    Published 2012
    “…It was estimated that 100 days of dust accumulation over mono-crystalline PV panels, caused the efficiency to decrease by around 10%. This limitation makes solar PV an unreliable source of power for unattended or remote devices and thus strongly suggests the challenge of cleaning the panel's surface regularly or injecting technical modifications. …”
