Cov qauv tseem ceeb ntawm nyias - zaj duab xis hnub ci cell yog PN hlws ris. Nws feem ntau muaj tsib txheej ntawm nyias - cov ntaub ntawv zaj duab xis nrog cov haujlwm sib txawv:
• Transparent conductive oxide (TCO) txheej: Ua hauj lwm raws li cov electrode pem hauv ntej ntawm lub xov tooj ntawm tes, tso cai rau lub teeb kom dhau mus thiab khaws cov tam sim no. Cov khoom siv feem ntau suav nrog indium tin oxide (ITO).
• P-hom semiconductor txheej: Tsim cov qhov, ua raws li cov txheej txheem thauj mus rau cov neeg nqa khoom photogenerated.
• Intrinsic semiconductor txheej (I txheej): Lub teeb tseem ceeb -absorbing txheej, feem ntau yog lub luag hauj lwm rau tiam thiab kev sib cais ntawm photogenerated electron- qhov khub.
• N- hom semiconductor txheej: Tsim cov khoom siv hluav taws xob, tsim cov tsim- hauv hluav taws xob ntawm PN hlws ris nrog P txheej.
• Back electrode txheej: Feem ntau yog ua los ntawm hlau, siv los sau cov tam sim no.
