hnub ci cell ntawv
Photovoltaic cov ntaub ntawv, tseem hu ua cov ntaub ntawv xov tooj ntawm hnub ci, xa mus rau cov ntaub ntawv uas tuaj yeem hloov ncaj qha hnub ci zog rau hauv hluav taws xob lub zog. Photovoltaic cov ntaub ntawv tuaj yeem tsim tawm tam sim no vim tias cov nyhuv photovoltaic, uas yog, yog tias lub teeb ci ci rau lub hnub ci cell thiab lub teeb tau nqus rau hauv interface txheej txheem, photons nrog lub zog txaus tuaj yeem ua rau nyiam electrons los ntawm covalent bonds hauv P-type silicon thiab N-type silicon, Yog li ua hluav taws xob.
