M'malo a mphamvu zowonjezereka, machitidwe ochepetsetsa a photovoltaic (PV) atuluka ngati teknoloji yodalirika, yopereka njira yowonjezereka komanso yowonjezereka yopangira magetsi a dzuwa. Mosiyana ndi mapanelo wamba a silicon-based solar, makina ocheperako a PV amakanema amagwiritsa ntchito wosanjikiza wocheperako wa zinthu za semiconductor zomwe zimayikidwa pagawo losinthika, kuzipangitsa kukhala zopepuka, zosinthika komanso zosinthika kuzinthu zosiyanasiyana. Cholemba ichi chabulogu chimayang'ana pazoyambira zamakanema opyapyala a PV, ndikuwunika magawo awo, magwiridwe antchito, ndi zabwino zomwe amabweretsa pakukonzanso mphamvu zamagetsi.
Zigawo za Thin Film PV Systems
Photoactive Layer: Mtima wa filimu yopyapyala PV system ndi chithunzi chojambulidwa, chomwe chimapangidwa kuchokera ku zinthu monga cadmium telluride (CdTe), copper indium gallium selenide (CIGS), kapena amorphous silicon (a-Si). Chosanjikizachi chimatenga kuwala kwa dzuwa ndikusintha kukhala mphamvu yamagetsi.
Gawo laling'ono: Chojambula chojambula chimayikidwa pagawo, chomwe chimapereka chithandizo chokhazikika komanso kusinthasintha. Zida zodziwika bwino za gawo lapansi zimaphatikizapo magalasi, pulasitiki, kapena zitsulo.
Encapsulation: Kuteteza chithunzithunzi ku zinthu zachilengedwe monga chinyezi ndi mpweya, chimakutidwa pakati pa zigawo ziwiri zoteteza, zomwe zimapangidwa ndi ma polima kapena magalasi.
Ma Electrodes: Zolumikizira zamagetsi, kapena maelekitirodi, amayikidwa kuti atenge magetsi opangidwa kuchokera pagawo lojambula.
Bokosi la Confluence: Bokosi la confluence limagwira ntchito ngati malo olumikizirana, kulumikiza ma module a dzuwa ndikuwongolera magetsi opangidwa ku inverter.
Inverter: The inverter imasintha magetsi apachindunji (DC) opangidwa ndi dongosolo la PV kukhala magetsi osinthika (AC), omwe amagwirizana ndi gridi yamagetsi ndi zida zambiri zapakhomo.
Kugwiritsa ntchito Thin Film PV Systems
Mayamwidwe a Dzuwa: Kuwala kwa dzuŵa kukakhala pagawo la photoactive, ma photon (mapaketi a mphamvu ya kuwala) amatengeka.
Chisangalalo cha Electron: Ma photon omwe alowetsedwa amasangalatsa ma elekitironi muzinthu zojambulidwa, kuwapangitsa kulumpha kuchokera kugawo lotsika lamphamvu kupita ku mphamvu yayikulu.
Kupatukana kwa Malipiro: Kusangalatsa kumeneku kumapangitsa kuti ma elekitironi asamayende bwino, pomwe ma elekitironi ochulukirapo amawunjikana mbali imodzi ndi mabowo a ma elekitironi (kupanda ma electron) mbali inayo.
Magetsi Akuyenda Pakalipano: Magawo amagetsi omangidwa mkati mwazinthu zojambulidwa amawongolera ma elekitironi olekanitsidwa ndi mabowo kupita ku maelekitirodi, ndikupanga magetsi.
Ubwino wa Thin Film PV Systems
Opepuka komanso Osinthika: Makina amtundu wa PV wocheperako amakhala opepuka komanso osinthika kwambiri kuposa mapanelo wamba a silicon, kuwapangitsa kukhala oyenera kugwiritsa ntchito zosiyanasiyana, kuphatikiza madenga, ma facade omanga, ndi mayankho amagetsi osunthika.
Kuchita Kwapang'onopang'ono: Makina opanga mafilimu ocheperako a PV amakonda kuchita bwino m'malo owala pang'ono poyerekeza ndi mapanelo a silicon, akupanga magetsi ngakhale masiku a mvula.
Scalability: Njira yopangira mafilimu opyapyala a PV ndi owopsa komanso osinthika kuti azitha kupanga zambiri, zomwe zingachepetse ndalama.
Kusiyanasiyana kwa Zida: Mitundu yosiyanasiyana ya zida za semiconductor zomwe zimagwiritsidwa ntchito pamakina opyapyala a PV amakupatsirani mwayi wowonjezera bwino komanso kuchepetsa mtengo.
Mapeto
Makanema a Thin film PV asintha mawonekedwe a mphamvu ya dzuwa, ndikupereka njira yodalirika yopita ku tsogolo lokhazikika komanso longowonjezera mphamvu. Chikhalidwe chawo chopepuka, chosinthika, komanso chosinthika, chophatikizana ndi kuthekera kwawo kotsika mtengo komanso kuwongolera magwiridwe antchito m'malo opepuka, zimawapangitsa kukhala kusankha kokakamiza pamagwiritsidwe osiyanasiyana. Pamene kafukufuku ndi chitukuko chikupitirirabe, machitidwe ochepetsetsa a PV a mafilimu atsala pang'ono kutenga gawo lalikulu kuti akwaniritse zosowa zathu za mphamvu zapadziko lonse m'njira yokhazikika komanso yosamalira chilengedwe.
