Emkhakheni wamandla avuselelekayo, izinhlelo zefilimu encane ye-photovoltaic (PV) ziye zavela njengobuchwepheshe obuthembisayo, obunikeza indlela eguquguqukayo futhi eyingozi yokukhiqiza ugesi welanga. Ngokungafani namaphaneli elanga asekelwe ku-silicon avamile, amasistimu efilimu amancane e-PV asebenzisa ungqimba oluncane lwempahla ye-semiconductor efakwe ku-substrate eguquguqukayo, ibenze ibe lula, iguquguquke, futhi ivumelane nezimo ezihlukahlukene zokusebenza. Lokhu okuthunyelwe kwebhulogi kudingida izisekelo zezinhlelo ze-PV zamafilimu amancanyana, zihlola izingxenye zazo, ukusebenza kwazo, kanye nezinzuzo ezizilethayo endaweni yamandla avuselelekayo.
Izingxenye ze-Thin Film PV Systems
Isendlalelo Sesithombe: Inhliziyo yesistimu yefilimu encane ye-PV ungqimba oluthwebulayo, ngokuvamile olwenziwe ngezinto ezifana ne-cadmium telluride (CdTe), i-copper indium gallium selenide (CIGS), noma i-amorphous silicon (a-Si). Lolu ngqimba lumunca ukukhanya kwelanga futhi luguqule lube amandla kagesi.
I-Substrate: Isendlalelo esinesithombe sifakwa ku-substrate, enikeza ukusekelwa kwesakhiwo nokuguquguquka. Izinto ezijwayelekile ze-substrate zifaka ingilazi, ipulasitiki, noma izinsimbi zensimbi.
I-Ecapsulation: Ukuze kuvikelwe isendlalelo esithwebula izithombe ezintweni zemvelo njengomswakama nomoya-mpilo, simbozwa phakathi kwezendlalelo ezimbili ezivikelayo, ngokuvamile ezenziwe ngamapholima noma ingilazi.
Ama-Electrodes: Okuthintana nabo ngogesi, noma ama-electrode, asetshenziswa ukuze kuqoqwe ugesi okhiqiziwe ovela kungqimba lwezithombe.
Ibhokisi lokuhlangana: Ibhokisi lokuhlangana lisebenza njengendawo yokuhlangana emaphakathi, elixhumanisa amamojula elanga ngalinye futhi lihambisa ugesi okhiqiziwe ku-inverter.
I-Inverter: I-inverter iguqula ugesi oqondile (DC) wamanje (DC) okhiqizwe uhlelo lwe-PV uwenze ugesi wamanje (AC) oshintshanayo, ohambisana negridi yamandla kanye nezinto eziningi zikagesi zasendlini.
Ukusebenza kwe-Thin Film PV Systems
Ukumunca Ukukhanya Kwelanga: Uma ukukhanya kwelanga kushaya ungqimba lwe-photoactive, ama-photon (amaphakethe wamandla okukhanya) ayamuncwa.
I-Electron Excitation: Ama-photon amunnyiwe ajabulisa ama-electron kokokusebenza okuthwebulayo, okuwenza eqe esuka endaweni ephansi yamandla aye kusimo samandla aphezulu.
Ukuhlukaniswa Kwezindleko: Lokhu kuvusa kudala ukungalingani kwezindleko, nama-electron amaningi anqwabelana ngakolunye uhlangothi kanye nezimbobo zama-electron (ukungabikho kwama-electron) kolunye.
Ukugeleza Kwamanje Kagesi: Izinkambu zikagesi ezakhelwe ngaphakathi ngaphakathi kwezinto ezithatha izithombe ziqondisa ama-electron ahlukanisiwe nezimbobo ukuya kuma-electrode, akhiqiza amandla kagesi.
Izinzuzo zama-Thin Film PV Systems
I-Lightweight futhi Iyavumelana nezimo: Izinhlelo ze-PV zefilimu ezacile zilula kakhulu futhi zivumelana nezimo kakhulu kunamaphaneli e-silicon avamile, awenza afanelekele izinhlelo zokusebenza ezihlukahlukene, okuhlanganisa uphahla, ama-facade wokwakha, nezixazululo zamandla aphathwayo.
Ukusebenza Kokukhanya Okuphansi: Amasistimu e-PV efilimu azacile ajwayele ukwenza kangcono ezimeni zokukhanya okuphansi uma kuqhathaniswa namaphaneli e-silicon, akhiqiza ugesi ngisho nangezinsuku zokusibekela.
I-Scalability: Inqubo yokukhiqiza yezinhlelo ze-PV zefilimu ezacile iyakala futhi ivumelana nezimo ekukhiqizeni ngobuningi, okungenzeka kunciphise izindleko.
Ukwehlukahlukana Kwezinto Ezisetshenziswayo: Izinhlobonhlobo zezinto ezisetshenziswa yisemiconductor ezisetshenziswa ezinhlelweni ze-PV zefilimu ezacile zinikeza ithuba lokuthuthuka okusebenzayo kanye nokwehliswa kwezindleko.
Isiphetho
Izinhlelo ze-PV zefilimu ezacile ziguqule isimo samandla elanga, zanikeza indlela ethembisayo ebheke ekusaseni lamandla aqhubekayo nelivuselelekayo. Imvelo yabo engasindi, eguquguqukayo, futhi evumelana nezimo, ehambisana namandla abo ezindleko eziphansi nokusebenza okuthuthukisiwe ezimeni zokukhanya okuphansi, kubenza babe ukukhetha okuphoqelekile kwezinhlelo zokusebenza eziningi. Njengoba ucwaningo nentuthuko iqhubeka, izinhlelo ze-PV zamafilimu amancanyana sezilungele ukudlala indima ebalulekile ekuhlangabezaneni nezidingo zethu zamandla omhlaba ngendlela esimeme nenakekela imvelo.
