    Yapay zekadan makale özeti

    Basic Equation
    • Shockley equation models exponential current-voltage relationship in diodes
    • Ideal diode equation has ideality factor 1-2, added for imperfect junctions
    • Thermal voltage typically 25.852 mV at 300 K
    • Reverse saturation current varies with temperature
    Limitations
    • Doesn't model internal resistance causing leveling off
    • Doesn't account for reverse breakdown region
    • Doesn't model noise or transient response
    Historical Development
    • Shockley derived voltage equation in 1949
    • Germanium diodes closely followed ideal equation in 1950
    • Pfann and van Roosbroek showed silicon junctions followed ideal equation in 1954
    Photovoltaic Applications
    • De Vos and Pauwels developed more rigorous photovoltaic equation in 1981
    • Equation applies to both illumination and thermal radiation
    • Current goes to infinity at gap voltage
    • Recently revised to account for temperature scaling
