Peb lub tuam txhab Maximum Power Point Tracking (MPPT) hnub ci maub los yog qhov tseem ceeb ntawm txhua lub hnub ci hluav taws xob tsim hluav taws xob. Tsim los txhim kho lub zog tsim hluav taws xob, tus tswj hwm qib siab no ua kom ntseeg tau tias cov hnub ci vaj huam sib luag ua haujlwm ntawm kev ua haujlwm siab tshaj plaws thiab hloov pauv mus rau ib puag ncig kev hloov pauv.#80a hnub ci tus nqi tswj

Thaum lub teeb ntawm qhov tsim nyog wavelength (thiab lub zog) tawm tsam cov txheej txheem ntawm tes thiab yog absorbed, electrons raug tso tawm mus random. Cov hluav taws xob ze rau ntawm ciam teb (pn junction) tuaj yeem cheb hla kev sib tshuam los ntawm qhov chaw ruaj khov. Vim hais tias cov electrons tuaj yeem hla ciam teb tau yooj yim, tab sis tsis tuaj yeem rov qab mus rau lwm qhov kev taw qhia (tawm tsam thaj tsam gradient), qhov kev tsis sib haum xeeb ntawm ob cheeb tsam semiconductor. Electrons raug rhais mus rau hauv n-txheej los ntawm cov teebmeem hauv cheeb tsam ntawm qhov chaw ruaj khov muaj lub ntuj nyiam tawm hauv txheej txhawm rau txhawm rau kho qhov tsis sib xws.

Txog rau qhov kawg no, cov electrons yuav ua raws lwm txoj hauv kev yog tias muaj. Los ntawm kev muab ib qho hluav taws xob sab nraud uas cov hluav taws xob tuaj yeem rov qab mus rau lwm txheej, cov dej ntws tam sim no yog tsim tawm uas yuav txuas ntxiv mus ntev npaum li lub teeb tawm tsam lub hnub ci. Nyob rau hauv kev tsim kho ntawm ib lub cell photovoltaic, hlau tiv thaiv txheej yog siv rau sab nrauv ntawm ob txheej semiconductor, thiab muab ib txoj hauv kev rau sab nraud Circuit Court uas txuas ob txheej. Qhov kawg tshwm sim yog kev tsim hluav taws xob hluav taws xob tau ncaj qha los ntawm lub zog ntawm lub teeb.
