Iimodyuli zeeseli zelanga, ezikwabizwa ngokuba ngamaphaneli elanga kunye neemodyuli ze-photovoltaic, ziyinxalenye ephambili yenkqubo yokuvelisa amandla elanga kunye neyona nxalenye ibalulekileyo yenkqubo yokuvelisa amandla elanga.Umsebenzi wayo kukuguqula amandla elanga kumandla ombane, okanye ukuyithumela kwibhetri yokugcina, okanye ukukhuthaza umsebenzi womthwalo.
Iimodyuli zeeseli zelanga zenziwe ngobuchule obuphezulu be-monocrystalline okanye iiseli ze-polycrystalline zelanga, i-iron ephantsi ye-ultra-white suede iglasi enomsindo, izinto zokupakisha (i-EVA, i-POE, njl.), i-backplanes esebenzayo, imivalo yokudibanisa, imivalo yebhasi, iibhokisi ze-junction kunye ne-aluminium alloy. izakhelo..
Umgaqo weeseli zelanga
Umguquli wamandla we-solar photovoltaic power generation yiseli yelanga, eyaziwa ngokuba yi-photovoltaic cell.Umgaqo wokuveliswa kwamandla elanga yi-photovoltaic effect.Xa ukukhanya kwelanga kukhanya kwiseli yelanga, iseli ifunxa amandla okukhanya kwaye ivelise iperi ye-electron-hole enefoto.Ngaphantsi kwesenzo sendawo yombane eyakhelwe-ngaphakathi yebhetri, ii-electron ezenziwe ngeefoto kunye nemingxunya ziyahlukana, kwaye ukuqokelelwa kweentlawulo ezichaseneyo kwenzeka kuzo zombini iziphelo zebhetri, oko kukuthi, "i-voltage photogenerated" yenziwe, leyo. yi "photovoltaic effect".Ukuba i-electrode izotywe kumacala omabini ombane owakhelwe ngaphakathi kwaye umthwalo uqhagamshelwe, umthwalo uya kuba ne "photo-generated current" ehambayo, ngaloo ndlela ufumana amandla ombane.Ngale ndlela, amandla okukhanya kwelanga aguqulwa ngokuthe ngqo abe ngumbane onokusetyenziswa.
Kwiqondo lokushisa elifanayo, umphumo wokukhanya kokukhanya kwipaneli yelanga: ubukhulu bokukhanya kokukhanya, ubukhulu be-voltage evulekileyo kunye ne-short-circuit current ye-solar panel, kunye namandla amakhulu okuvelisa amandla.Ngexesha elifanayo, kunokubonwa ukuba i-voltage ye-open-circuit voltage iyatshintsha kunye nokuqina kwe-irradiation.Ayicacanga njengotshintsho lwe-short-circuit current kunye nokuqina kwe-irradiation.
Ngaphantsi kokukhanya okufanayo, umphumo weqondo lokushisa kwipaneli: xa iqondo lokushisa leseli yelanga linyuka, i-voltage ye-open-circuit voltage iyancipha kakhulu ngeqondo lokushisa, kwaye i-short-circuit current inyuka kancinane, kwaye umkhwa jikelele kukuba. amandla emveliso aphezulu ayancipha
Iimpawu zeeseli zelanga
Imodyuli yeseli yelanga ine-photoelectric ephezulu yokuguqulwa kwe-photoelectric kunye nokuthembeka okuphezulu;itekhnoloji yokusasazwa okuphezulu iqinisekisa ukufana koguqulo olusebenzayo kuyo yonke i-chip;iqinisekisa ukuhanjiswa kombane okulungileyo, ukubambelela okuthembekileyo kunye ne-electrode solderability elungileyo;ukuchaneka okuphezulu I-silika-screen eprintiweyo imizobo kunye ne-flatness ephezulu yenza ibhetri ibe lula kwi-welding ngokuzenzekelayo kunye nokusika kwe-laser.
Ngokwezixhobo ezahlukeneyo ezisetyenzisiweyo, iiseli zelanga zinokwahlulwa zibe: iiseli ze-silicon zelanga, iiseli zelanga ze-silicon, iiseli zelanga ze-polymer multilayer eziguqulweyo, iiseli zelanga ze-nanocrystalline, iiseli zelanga ze-organic, iiseli zelanga zeplastiki, phakathi kwazo iiseli zelanga ze-silicon. Iibhetri zezona zikhulileyo kwaye zilawula usetyenziso.
