Amaseli elanga, aziwa nangokuthi amaseli e-photovoltaic, aguqula ngqo ukukhanya kwelanga kube amandla kagesi. Ukulinganisa ukusebenza kahle kwamaseli elanga ngokuvamile kuhilela ukuhlola amandla okukhanya kwelanga okwenzeka ngengozi kusetshenziswa i-radiometer nokunquma ukuphuma kwamandla kagesi endaweni yamandla ephezulu kakhulu. Kodwa-ke, le nqubo ibhekene nezinselele ngenxa yokuncika kokusebenza kwamaseli ku-spectrum yelanga, okuhlukahluka ngokushintsha kwesizini, indawo, kanye nezimo zezulu. Lezi zici, kuhlangene namaphutha okulinganisa kuma-radiometer, kungaholela ekulinganisweni okungalingani nokunganembile.
Ukuze kuncishiswe izinkinga ezinjalo, abakhiqizi abaningi basebenzisa izilingisi zelanga ukuhlola ukusebenza kahle kwamaseli elanga ezindaweni ezilawulwayo. Lawa ma-simuling alinganiswa kusetshenziswa amaseli ajwayelekile ahambisana nokusatshalaliswa kokukhanya kwelanga ngaphansi kwezimo ezijwayelekile.
Izingibe Ezivamile Ekuhlolweni Kwamaseli Elanga Angama-Silicon Anombala Omncane
Amanye amalabhorethri kanye nezinhlangano zokuhlola zisebenzisa amaseli e-silicon acwebezelayo njengezindinganiso zokubhekisela ukuhlola amaseli e-silicon thin-film angenawo ukwakheka. Lo mkhuba uvame ukuholela emaphutheni amakhulu okulinganisa, okuholela ekungabazeni ngokusebenza kwamaseli e-silicon angenawo ukwakheka.
Izindinganiso Zomhlaba Wonke Zokuhlola Amaseli Elanga
Ukuqinisekisa ukuqhathanisa okuhambisanayo nokuthembekile, amazinga okuhlola omhlaba wonke achaza izimo ezithile zokuhlolwa kwamaseli elanga:
I-Spectrum: AM1.5
Ukukhanya: 1000 W/m²
Izinga lokushisa: 25°C
I-AM1.5 ibhekisela ku-spectrum yelanga lapho ukukhanya kwelanga kudlula emoyeni nge-engeli ehambisana ne-engeli ye-zenith engu-48.2°.
Ukuze kulinganiswe kahle, kufanele kuhlangatshezwane nezimo ezimbili ezibalulekile:
Impendulo ye-spectral yeseli yokubhekisela kanye neseli yokuhlola kumele ivumelane ngaphakathi kobubanzi obucacisiwe, okuvame ukufezwa ngokusebenzisa amaseli okubhekisela nawokuhlola enziwe ngezinto ezifanayo ze-semiconductor kanye nezinqubo zokukhiqiza ezifanayo.
Umthombo wokukhanya ku-simulator kumele uhambisane eduze nokwakheka kwe-spectral kwe-AM1.5 standard.
Izinto Ezibalulekile Okufanele Uzicabangele Ngamaseli E-Silicon Amorphous
Amaseli e-silicon angenasimo ahluke kakhulu kumaseli e-silicon acwebezelayo ngokwezinto ezibonakalayo kanye nokusabela kwe-spectral. Nazi izinto ezibalulekile okufanele uzicabangele ukuze uhlole ngokunembile:
Ukulinganiswa Kokukhanya:
Sebenzisa iseli lokubhekisela le-silicon elingaguquki elenzelwe ngqo ukulinganisa ukukhanya. Ukusebenzisa amaseli e-silicon acwebezelayo ngale njongo kungaholela emiphumeleni engenamsebenzi ngenxa yokungafani kwe-spectral. Ngisho noma ngabe umthombo wokukhanya ofanele uyatholakala, ukuqinisekisa imiphumela enembile ezindaweni ezijwayelekile zelebhu noma zokukhiqiza kusalokhu kuyinselele.
Ukukhethwa Komthombo Wokukhanya:
I-solar simulator kufanele isebenzise umthombo wokukhanya onobubanzi be-spectral obuphakathi kuka-300 nm no-800 nm obufana kakhulu ne-AM1.5 spectrum. Ama-xenon lamp simulator avamile avame ukuba ne-infrared-rich spectrum (800 nm kuya ku-1100 nm) ephambuka ku-standard, okubangela ukungafani okukhulu.
Impendulo ye-Spectral:
Impendulo ye-spectral yeseli yelanga ibhekisela enanini labathwali beshaja abakhiqizwa nge-photon ngayinye kubude obunikeziwe. Amaseli e-silicon angenawo ukwakheka anobubanzi bempendulo ye-spectral obungu-400 nm kuya ku-800 nm, uma kuqhathaniswa namaseli e-silicon angenawo ukwakheka angu-400 nm kuya ku-1100 nm kumaseli e-silicon angenawo ukwakheka. Lapho kuhlolwa amaseli e-silicon angenawo ukwakheka kusetshenziswa ama-simulators alinganiswe nezindinganiso ze-silicon ezi-crystalline, i-spectrum ecebile nge-infrared (800 nm kuya ku-1100 nm) inegalelo kugesi wamaseli e-crystalline kodwa hhayi kumaseli angenawo ukwakheka. Lokhu kuphumela ekungalinganisweni okukhulu kokusebenza kwamanje kweseli le-silicon elingenawo ukwakheka kanye nokusebenza kwayo yonke indawo.
Ngaphezu kwalokho, impendulo ye-spectral yamaseli e-silicon angenawo ukwakheka ithonywa yizici ezifana nokukhanya kwe-bias kanye ne-voltage, okwenza kube kubalulekile ukubheka lezi ziguquguquko ngaphansi kwezimo ezingezona ezejwayelekile.
Ukuhlolwa okunembile kwamaseli elanga e-silicon amorphous thin-film kudinga ukunakwa ngokucophelela ekulinganisweni kokukhanya, ukukhethwa komthombo wokukhanya, kanye nokuqondaniswa kwempendulo ye-spectral. Ukunamathela kulezi ziqondiso kuqinisekisa imiphumela ethembekile futhi kugwema amaphutha ahlobene nezindlela zokulinganisa ezingafanele.
