Lub hauv paus ntsiab lus ua haujlwm ntawm hnub ci photovoltaic lub zog tsim hluav taws xob: Hnub ci photovoltaic tsim hluav taws xob tso siab rau lub hnub ci cell modules, siv cov khoom siv hluav taws xob ntawm cov khoom siv semiconductor. Thaum tshav ntuj ci rau ntawm lub semiconductor PN hlws ris, ib qho muaj zog built-in electrostatic teb yog generated nyob rau hauv lub PN junction barrier cheeb tsam, uas ua rau cov tiam ntawm non-equilibrium electrons thiab qhov nyob rau hauv lub barrier cheeb tsam los yog diffusion ntawm non-equilibrium electrons thiab qhov. sab nraum lub barrier cheeb tsam mus rau hauv lub barrier cheeb tsam. Nyob rau hauv qhov kev txiav txim ntawm built-in electrostatic teb, Tsiv nyob rau hauv opposite lus qhia thiab tawm hauv lub barrier cheeb tsam, qhov tshwm sim yog ib tug nce nyob rau hauv lub P- cheeb tsam muaj peev xwm thiab ib tug txo nyob rau hauv lub N- cheeb tsam muaj peev xwm, uas generates voltage thiab tam sim no nyob rau hauv lub sab nraud. Circuit Court thiab hloov lub teeb lub zog rau hauv hluav taws xob hluav taws xob.
