Ukusetshenziswa kwemitha yomthombo wokunemba okuphezulu ekuhlolweni kwesici seseli yelanga

Ngokuthuthuka okusheshayo komnotho womhlaba kanye nokudlondlobala kwezimboni, isidingo sabantu samandla sikhula usuku nosuku. Uma kuqhathaniswa namandla kaphethiloli angavuseleleki, imisebe yelanga ingagcina ukuphuma okungashintshile amashumi ezinkulungwane zeminyaka, futhi ukuguqulwa kwamandla okukhanya abe amandla kagesi kuyinqubo ebaluleke kakhulu. Amaseli elanga awuhlobo lweshidi le-photoelectric semiconductor elisebenzisa ukukhanya kwelanga ukukhiqiza ugesi ngokuqondile. Uma ukukhanya kuhlangabezana nezimo ezithile, kungakhipha i-voltage ngokushesha futhi kukhiqize i-current in the presence of a circuit. Isetshenziswa kabanzi emikhakheni ehlukahlukene efana nezokuthutha, ezokuxhumana, namasathelayithi.

Kusukela ocwaningweni nasekuthuthukisweni kuya ekukhiqizeni, amaseli elanga anezidingo ezihlukene zokuhlola kusixhumanisi ngasinye. Izici zabo ze-photoelectric zifaka izici ze-volt-ampere IV, izici ze-spectral impendulo ye-SR, nezici ze-quantum ze-QE ezisebenza kahle. Phakathi kwazo, ukuhlaziywa kwesici se-IV kubalulekile ekutholeni amapharamitha abalulekile ahlobene nokusebenza kwamaseli elanga, ikakhulukazi okuhlanganisa i-I-max ephezulu yamanje kanye ne-voltage V-max, i-voltage yesifunda evulekile i-Voc, i- short circuit current Isc, i-factor factor ff, nokusebenza kahle kokuguqulwa η. Ukuze uqedele ngokunembile ukuhlolwa kwesici se-IV samaseli elanga, umhloli udinga ukusebenzisa umthombo wokukhanya wesifanisi selanga ukuze akhanyise isampula ngebanga elithile, bese esebenzisa amathuluzi kagesi anembayo ukukala ijika lophawu lwe-IV ukuze athole amapharamitha ebhethri.

Uma kungenakukhanya, i-DC eshiwo i-bias voltage iyadingeka ukukala izici ze-IV zamaseli elanga, futhi ijika lesici se-IV ngaphansi kwe-voltage yokuchema eya phambili iyalinganiswa; uma ingekho i-voltage echema, izici ze-IV zamaseli elanga ngaphansi kwezimo ezihlukene zomthwalo zikalwa ngokukhanya kwesigameko kwamaza ahlukahlukene (izici zomthwalo wochungechunge oluningi zisobala kakhulu), kanye ne-Isc yamanje yesiyingi esifushane, i-voltage ye-open-circuit Voc , amandla aphezulu, ukusebenza kahle kwamanje kanye ne-voltage kuyalinganiswa. Uchungechunge lwemitha yomthombo wedijithali ye-NGI N2600 enembayo ephezulu ihlanganisa imisebenzi yokulinganisa umthombo, ingakhipha umthombo wamandla kagesi wokunemba okuphezulu kakhulu kanye nomthombo wamanje, futhi inikeza imisebenzi yokulinganisa, engahlangabezana ngokugcwele nezidingo zokuhlola izici ze-solar cell IV.

I-Spectral response SR inkomba yokuhlola amandla okuguqulwa kwe-photoelectric yamaseli elanga. Nikeza ukukhanya kwesigameko kwamaza ahlukahlukene, futhi isilinganiso samanje esiguquliwe ngemva kokuthola ukukhanya kwesigameko kumandla okukhanya kwesigameko kuyimpendulo ye-spectral SR. Imitha yomthombo wochungechunge lwe-N2600 ingakala ngokunembile i-photocurrent ukuze iqedele ukuhlolwa kwesici samanje se-SR.

Ngokuvamile, ukunikezwa kwamandla kunikeza kuphela ukusebenza kwe-quadrant yokuqala neyesithathu, ekhipha amandla njengomthombo. Uchungechunge lwe-N1 lungahlinzeka ngokusebenza okugcwele kwama-quadrant amane. Uma isebenza ku-3nd ne-2600th quadrants, ingakwazi ukumunca amandla njengesinki (umthwalo). Kumodi yomthombo noma yokucwila, ingakala i-voltage, yamanje kanye nokumelana. Ijubane layo eliphezulu lokusampula lingafinyelela ku-2ksps, futhi isivinini sokuskena singu-4ms ngephuzu ngalinye.
