Ukusetyenziswa kwemitha yomthombo echanekileyo ephezulu kuvavanyo lweempawu zeseli yelanga

Ngokukhula okukhawulezayo koqoqosho lwehlabathi kunye nokuqina koshishino, imfuno yabantu yamandla iyanda imihla ngemihla. Xa kuthelekiswa namandla efosili engahlaziyekiyo, imitha yelanga inokugcina imveliso engaguqukiyo amashumi eebhiliyoni zeminyaka, kwaye ukuguqulwa kwamandla okukhanya abe ngamandla ombane yinkqubo ebaluleke kakhulu. Iiseli zelanga luhlobo lwephepha le-photoelectric semiconductor elisebenzisa ukukhanya kwelanga ukuvelisa umbane ngokuthe ngqo. Xa ukukhanya kuhlangabezana neemeko ezithile, kunokukhupha i-voltage ngokukhawuleza kwaye kuvelise i-current phambi kwesekethe. Isetyenziswa kakhulu kwiinkalo ezahlukeneyo ezifana nezothutho, unxibelelwano, kunye neesathelayithi.

Ukusuka kuphando kunye nophuhliso ukuya kwimveliso, iiseli zelanga zineemfuno ezahlukeneyo zokuvavanya kwikhonkco ngalinye. Iimpawu zabo ze-photoelectric ziquka iimpawu ze-volt-ampere IV, iimpawu ze-SR ze-spectral, kunye neempawu ze-QE ze-quantum. Phakathi kwazo, uhlalutyo lweempawu ze-IV lubalulekile ekufumaneni iiparamitha ezibalulekileyo ezinxulumene nokusebenza kweeseli zelanga, ngakumbi kubandakanya i-I-max ephezulu yangoku kunye ne-voltage V-max, i-voltage ye-voltage evulekileyo yeVoc, i-Isc yesiphaluka esifutshane, i-factor factor ff, kunye nokusebenza kakuhle kokuguqulwa η. Ukuze ugqibezele ngokuchanekileyo uvavanyo lweempawu ze-IV zeeseli zelanga, umvavanyi kufuneka asebenzise umthombo wokukhanya we-simulator yelanga ukuze akhuphe isampuli kumgama othile, kwaye emva koko asebenzise izixhobo zombane ezichanekileyo ukulinganisa ijika leempawu ze-IV ukufumana iiparamitha zebhetri.

Xa kungekho kukhanya, i-voltage ekhankanyiweyo ye-DC iyafuneka ukulinganisa iimpawu ze-IV zeeseli zelanga, kunye ne-IV ye-curve yeempawu phantsi kombane ohamba phambili ohamba phambili uyalinganiswa; xa kungekho mandla ombane ocalanye, iimpawu ze-IV zeeseli zelanga phantsi kweemeko ezahlukeneyo zomthwalo zilinganiswa ngokukhanya kwesiganeko samaza ahlukeneyo (iimpawu zomthwalo wechungechunge ezininzi zicace ngakumbi), kunye ne-Isc ye-short-circuit yangoku, i-voltage evulekileyo ye-Voc , amandla aphezulu, ukusebenza ngokufanelekileyo kunye ne-voltage iyalinganiswa. Uluhlu lwe-NGI N2600 oluchanekileyo oluchanekileyo lwemitha yomthombo wedijithali ludibanisa imisebenzi yokulinganisa umthombo, inokukhupha umthombo we-voltage ye-ultra-high-precision umthombo kunye nomthombo wangoku, kwaye ibonelele imisebenzi yokulinganisa, enokuthi ihlangabezane ngokupheleleyo neemfuno zovavanyo lweempawu ze-solar cell IV.

Impendulo ye-Spectral SR sisalathisi sokuvavanya amandla okuguqula i-photoelectric yeeseli zelanga. Ukubonelela ngokukhanya kwesiganeko se-wavelengths eyahlukeneyo, kunye nomlinganiselo wangoku oguqulweyo emva kokufumana ukukhanya kwesiganeko kwisiganeko samandla okukhanya yimpendulo ye-spectral SR. Uluhlu lwemitha yomthombo we-N2600 inokulinganisa ngokuchanekileyo i-photocurrent ukugqiba uvavanyo lwangoku lweempawu ze-SR.

Ngokuqhelekileyo, izixhobo zombane zibonelela kuphela ukusebenza kwe-1 kunye ne-3rd quadrant, ekhupha amandla njengomthombo. Uluhlu lwe-N2600 lunokubonelela ngokusebenza okupheleleyo kwee-quadrant ezine. Xa usebenza kwi-2 kunye ne-4th quadrants, inokuthatha amandla njenge-sink (umthwalo). Kumthombo okanye kwimodi ye-sink, inokulinganisa i-voltage, yangoku kunye nokuchasana. Isantya salo esikhulu sokulinganisa sinokufikelela kwi-100ksps, kwaye isantya sokuskena si-1ms ngenqaku ngalinye.
