Gabatarwar Samfur
Yayin da fasahar photovoltaic ke ci gaba, wani sabon nau'in samfurin PV ya bayyana a bangaren samarwa wanda ya bambanta da na'urorin hasken rana na gilashi. Ya fi sauƙi, mai sassauƙa, kuma mafi dacewa don amfani. Wannan shi ne na'urar hasken rana mai sassauƙa, wanda galibi ake kira semi-flexible panel a masana'antar.
Modulolin PV masu sassauci suna da fa'idodi da dama. Suna rufe yanayin hasken rana da aka rarraba kamar rufin ƙarfe mai launi na kasuwanci da masana'antu, rufin lebur, gidajen tayal na zama, da haɗin gine-gine da hasken rana (BIPV). Har ila yau sun dace da yanayi na musamman kamar hasken shimfiɗar wuri, tushen wutar lantarki mai ɗaukar nauyi, robobi, da ayyukan waje.
Tare da fa'idodi kamar taushi da sassauci, nauyi mai sauƙi da ɗaukar nauyi, kyakkyawan siffa, inganci mai girma, da kasancewa abokiyar muhalli, modulolin masu sassauci suna ƙara zama abin so a fannin sabon makamashi, suna samun ƙarin amincewar masu amfani. Yau bari mu ɗan duba tsarin samarwa da tsarin modulolin PV masu sassauci.
Module Structure
Ga zanen tsari da hoton talla na modul PV mai sassauci da aka samu a yanar gizo:
Muna iya ganin cewa modul ɗin yana da tsarin yadudduka 7: ETFE + EVA + Kwayoyin (sashin samar da wuta) + EVA + PET + EVA + TPT. A ƙasa mun bayyana aikin kowane yadi.
Layer Functions
ETFE Front Sheet
ETFE (ethylene-tetrafluoroethylene copolymer) yana aiki a matsayin gaban takardar mai sassauƙa, wanda ya maye gurbin gilashin gargajiya. Yana bayar da babban haske watsawa (yawanci >94%), kyakkyawan juriya ga yanayi, juriya ga UV, da juriya ga lalacewar sinadarai. Yana ba da kariya ta waje ga na'urar yayin da yake tabbatar da ingantaccen watsa haske.
Fim ɗin Rufe EVA
Fim ɗin EVA (ethylene-vinyl acetate copolymer) yana da alhakin haɗawa da rufewa. Yana haɗa gaban takardar ETFE da ƙarfi zuwa layin samar da wutar lantarki, yayin da yake toshe tururin ruwa da oxygen, rage damuwa, da kare sel.
Layin Samar da Wutar Lantarki (Sel)
Sel sune babban bangaren samar da wutar lantarki na module. Suna yin canjin photoelectric, suna juya hasken rana da ke isa ga sel zuwa wutar lantarki.
EVA (Layer na Biyu)
Wannan Layer na EVA yana aiki azaman kayan rufewa, yana haɗa ɗayan gefen sel zuwa layukan da ke gaba. Aikin sa iri ɗaya ne da na EVA na sama.
Layer na Tallafi na PET
PET yawanci yana aiki azaman layer na tallafi na tsakiya ko a matsayin rufin ciki na backsheet. A cikin wannan sassauƙan tsari yana kasancewa a matsayin rufin tsakiya, yana ba da ƙarfin injiniya, rufin wutar lantarki, da kuma wani matakin shingen tururin ruwa. Duk da haka, juriyar sa na UV da damshi-zafi yana da iyaka, don haka ya dogara da kariyar layer na waje. Wasu modules masu sassauƙa suna sanya PET sama da layer na cell.
Fim ɗin EVA (Layer na Haɗawa)
Wannan fim ɗin EVA yana haɗa layer na PET zuwa backsheet na waje (TPT), yana tabbatar da mannewa tsakanin layuka da kuma hana rabuwa.
Fim ɗin Hana Fasa
Fim ɗin anti-crack yana haɗa sel ɗin kuma yana hana ƙananan tsagewa a cikin sel ɗin lokacin da aka lanƙwasa module ɗin.
Filin Baya na TPT
TPT backsheet shine mafi bayan Layer na module ɗin. Tsarinsa shine PVF (polyvinyl fluoride) fim + PET substrate + PVF fim, inda PVF fim wani polymer ne da aka fitar daga copolymers na fluorine da fluorocarbon molecules. Dalilin da yasa ake kiran wannan tsari da TPT backsheet shine kamfanin Amurka DuPont sanannen mai samar da PVF fim ne. Alamar kasuwanci ta DuPont ga PVF fim ita ce Tedlar, wacce aka taƙaita ta a matsayin "T" a cikin tsarin backsheet, yayin da "P" ke nufin PET substrate na tsakiya.
Babban ayyukan TPT tsarin backsheet sune: fim ɗin fluorine na waje yana ba da kyakkyawan juriya ga yanayi, juriya ga UV, da juriyar lalacewar muhalli; Layer PET na tsakiya yana ba da tallafin injiniya, rufin wutar lantarki, kuma babban shingen tururin ruwa; fim ɗin fluorine na ciki yana da kyakkyawan mannewa tare da fim ɗin EVA, yana tabbatar da backsheet ɗin yana manne da tsarin rufewa da ƙarfi.

Na'urorin PV masu sassauƙa suna amfani da ETFE maimakon gilashi a matsayin gaban takardar, yadudduka da yawa na EVA don haɗawa da kariya ta rufewa, PET a matsayin matsakaiciyar ƙarfafa Layer, da TPT a matsayin bayan takardar da ke jure yanayi. Tare suna ba da cikakkiyar kariya ta jiki, rufewar muhalli, da dogon lokaci ga ƙaramin Layer na samar da wutar lantarki. A lokaci guda, masana'anta suna ƙirƙirar siffar zuma a saman na'urar don inganta samar da wutar lantarki.
