Iiseli zelanga, ezaziwa ngokuba ziiseli ze-photovoltaic, ziguqula ngokuthe ngqo ukukhanya kwelanga kube ngamandla ombane. Ukulinganisa ukusebenza kakuhle kweeseli zelanga kudla ngokubandakanya ukuvavanya amandla okukhanya kwelanga okwenzekileyo kusetyenziswa i-radiometer kunye nokufumanisa amandla ombane aphuma kwindawo ephezulu yamandla. Nangona kunjalo, le nkqubo ijongene nemingeni ngenxa yokuxhomekeka kokusebenza kweeseli kwi-spectrum yelanga, eyahluka ngotshintsho lwexesha lonyaka, indawo, kunye neemeko zemozulu. Ezi zinto, kunye neempazamo zokulinganisa kwi-radiometers, zinokukhokelela ekulinganisweni okungahambelaniyo nokungachanekanga.
Ukunciphisa iingxaki ezinjalo, uninzi lwabavelisi basebenzisa ii-solar simulators ukuvavanya ukusebenza kakuhle kweeseli zelanga kwiindawo ezilawulwayo. Ezi simulators zilinganiswa kusetyenziswa iiseli ezisemgangathweni ezihambelana nokusasazwa kwelanga kwe-spectral phantsi kweemeko eziqhelekileyo.
Iingxaki Eziqhelekileyo Ekuvavanyweni Kweeseli Zelanga Ezincinci ZeSilicon Ezingenawo Umzimba
Ezinye iilabhoratri kunye neearhente zovavanyo zisebenzisa iiseli ze-silicon ezikristale njengemigangatho yokubhekisa ukuvavanya iiseli ze-silicon ezingathathi cala. Olu qheliselo ludla ngokubangela iimpazamo ezinkulu zokulinganisa, nto leyo ekhokelela kumathandabuzo malunga nokusebenza kweeseli ze-silicon ezingathathi cala.
Imigangatho yaMazwe ngaMazwe yoVavanyo lweeSeli zeLanga
Ukuqinisekisa uthelekiso oluhambelanayo noluthembekileyo, imigangatho yovavanyo lwamazwe ngamazwe ichaza iimeko ezithile zovavanyo lweeseli zelanga:
I-Spectrum: AM1.5
Ukukhanya: 1000 W/m²
Ubushushu: 25°C
I-AM1.5 ibhekisa kwi-spectrum yelanga xa ukukhanya kwelanga kudlula emoyeni nge-engile ehambelana ne-engile ye-zenith ye-48.2°.
Ukuze kulinganiswe ngokuchanekileyo, kufuneka kuhlangatyezwane neemeko ezimbini ezibalulekileyo:
Impendulo ye-spectral yeseli yesalathiso kunye neseli yovavanyo kufuneka ihambelane ngaphakathi koluhlu oluchaziweyo, oluqhele ukufezekiswa ngokusebenzisa iiseli zesalathiso kunye neeseli zovavanyo ezenziwe ngezinto ezifanayo ze-semiconductor kunye neenkqubo ezifanayo zokuvelisa.
Umthombo wokukhanya kwi-simulator kufuneka uhambelane ngokusondeleyo nokwakheka kwe-spectral yomgangatho we-AM1.5.
Izinto Ezibalulekileyo Eziqwalaselweyo Ngee-Silicon Cells Ezingenawo Umzimba
Iiseli ze-silicon ezi-amorphous zahluke kakhulu kwiiseli ze-silicon ezikristale ngokweempahla kunye nempendulo ye-spectral. Nazi izinto ezibalulekileyo ekufuneka ziqwalaselwe ukuze kuvavanywe ngokuchanekileyo:
Ukulinganiswa kwe-Irradiance:
Sebenzisa iseli yesalathiso sesilicon esingenasimo semvelo eyenzelwe ngokukodwa ukulinganisa ukukhanya. Ukusebenzisa iiseli zesilicon ezikristale kule njongo kunokukhokelela kwiziphumo ezingenamsebenzi ngenxa yokungafani kwe-spectral. Nokuba umthombo wokukhanya ofanelekileyo ubukho, ukuqinisekisa iziphumo ezichanekileyo kwiindawo eziqhelekileyo zelebhu okanye zemveliso kusengumngeni.
Ukhetho loMthombo wokukhanya:
Isilayidi selanga kufuneka sisebenzise umthombo wokukhanya onobubanzi be-spectral obuphakathi kwe-300 nm kunye ne-800 nm obuhambelana ngokusondeleyo ne-AM1.5 spectrum. Iisilayidi zezibane ze-xenon eziqhelekileyo zihlala zine-spectrum etyebileyo ye-infrared (800 nm ukuya kwi-1100 nm) ephambukayo kumgangatho, nto leyo ebangela ukungalingani okukhulu.
Impendulo yeSpectral:
Impendulo ye-spectral yeseli yelanga ibhekisa kwinani leenkampani ezithwala itshaja eziveliswa yi-photon nganye kubude obuthile. Iiseli ze-silicon ezi-Amorphous zinoluhlu lwempendulo ye-spectral oluyi-400 nm ukuya kwi-800 nm, xa kuthelekiswa ne-400 nm ukuya kwi-1100 nm kwiiseli ze-silicon ezi-crystalline. Xa kuvavanywa iiseli ze-silicon ezi-amorphous kusetyenziswa ii-simulators ezilinganiswe ngemigangatho ye-silicon e-crystalline, i-infrared-rich spectrum (800 nm ukuya kwi-1100 nm) inegalelo kumbane weeseli ze-crystalline kodwa hayi kwiiseli ezi-amorphous. Oku kubangela ukungaqwalaselwa kakuhle kwamandla ombane kunye nokusebenza ngokubanzi kweseli ye-silicon e-amorphous.
Ukongeza, impendulo ye-spectral yeeseli ze-silicon ezi-amorphous iphenjelelwa zizinto ezifana nokukhanya kwe-bias kunye ne-voltage, nto leyo eyenza kube yimfuneko ukuphendula ezi zinto phantsi kweemeko ezingaqhelekanga.
Uvavanyo oluchanekileyo lweeseli zelanga ze-silicon ezithambileyo zefilimu ethambileyo lufuna ingqalelo ebukhali ekulinganisweni kwemitha, ukukhethwa komthombo wokukhanya, kunye nokulungelelaniswa kwempendulo ye-spectral. Ukunamathela kwezi zikhokelo kuqinisekisa iziphumo ezithembekileyo kwaye kuthintela iimpazamo ezinxulumene neendlela ezingafanelekanga zokulinganisa.
