PowerPoint Slide Presentation I/V Slides Example
Solar cell I/V curve 2.2cm x 1.7 cm = 3.74cm 2 Aluminum top contact metal Voc = 0.4v Isc = 70mA Imax = 80 mA
Vmp = 0.2v Imp = 35mA FF = Vmp x Imp/Voc x Isc = (0.2)(.035)/(0.4)(0.070) =.007/.028 =.250 n = Pout / Pin = (0.2V)(35mA)/374mW = 7mW/374mW =.018 = 1.8% Pin = 100mW/cm 2 For this cell area = 3.74cm 2 Pin = 374mW You can zoom in and print a section of the graph larger to make measurements easier
