Ilebhu yovavanyo lwe-elektroniki ehamba phambili yabelane ngamava ayo ne- Izixhobo zokuqhuba ibhayisekile ze-THR10-500Akunye nee-oveni zokomisa: "Igumbi lethu le-THR10-500A kunye nee-oveni zokomisa zisebenza kakuhle kakhulu, enkosi. Siyavuya kakhulu ngazo." Ukusebenza okuzinzileyo kwegumbi ngexesha lovavanyo olunamandla lokuhamba ngebhayisekile yobushushu kwenza iqela lakwazi ukwenza iinkqubo zokutsha ixesha elide kunye nokutshintsha okukhawulezayo kobushushu ngaphandle kokuphazamiseka. Oku kuthembeka kwabanika ukuzithemba ekuhloleni ngokuchanekileyo ukuqina kobushushu kunye nokuqina kwezixhobo ze-elektroniki zeemoto, izinzwa, kunye neemodyuli zolawulo. Ngaphaya kwezixhobo ze-elektroniki, izixhobo zibonakalise zisebenza kakuhle kuvavanyo lwezinto, ukuguga kwezixhobo zeplastiki, kunye novavanyo lokusebenza kwebhetri, ukunceda amaqela ukuba alingise ngokufanelekileyo iimeko zobushushu zehlabathi lokwenyani kwaye aphucule ubude bexesha lemveliso.

Kutheni iiphaneli zelanga zifuna uvavanyo lwebhayisikile yobushushu?

​Iminyaka Elishumi Yokuchatshazelwa Ngaphandle Nobushushu Obugqithisileyo

Uphahla okanye uluhlu lwelanga oluxhonywe emhlabeni lujongene nokuchatshazelwa ngaphandle kwesikhuseli kwiimeko ezingaqhelekanga zexesha lonyaka - ihlobo elitshisayo, ubusika obubandayo, nayo yonke into ephakathi. Ukufakelwa kwentlango kuhlangabezana nomahluko wemihla ngemihla odlula ama-50°C, ngelixa iindawo zaseNordic zinyamezela iimeko ezinde ezingaphantsi kwe-zero. Kwixesha lewaranti yeminyaka engama-25, iphaneli enye inokuqokelela amashumi amawaka emijikelo yobushushu, nganye icinezela ngokuthe ngcembe ujongano lwangaphakathi kunye nonxibelelwano.

Iindlela zokudinwa eziQokelelweyo kwiimodyuli zePV

Ukutshintshatshintsha kobushushu ngakunye kubangela ukwanda kunye nokucutheka kwezinto ezahlukeneyo ezidityaniswe ngaphakathi kwe-module laminate. Ukudinwa kuyaqhekeka kwiindawo zoxinzelelo - ingakumbi amalungu e-solder adibanisa iiseli ze-silicon kwiiribhoni zobhedu - kwaye asasaze umjikelo emva komjikelo. Ngaphandle kovavanyo lokujikeleza kobushushu, ezi ziphene ezikhula kancinci ziyabaleka ekubonweni ngexesha lokuhlolwa kombane rhoqo kwisango lomzi-mveliso.

Izibonelelo zoqoqosho zokuwohloka kwephaneli ngaphambi kwexesha

Uqoqosho lweeprojekthi zelanga luxhomekeke kwimveliso yamandla eqikelelweyo kwiminyaka emininzi edlulileyo. Imodyuli ewohloka ngokukhawuleza kunokuba bekulindelwe itshabalalisa imbuyekezo yabatyali-mali, ibangele amabango ewaranti, kwaye yonakalisa udumo lomenzi. Ukufaneleka okuqinileyo kokujikeleza kobushushu kusetyenziswa amagumbi ovavanyo akhiwe ngenjongo kubamba uyilo olubuthathaka kwangethuba, okuvumela ukulungiswa okukhusela imithombo yengeniso kunye nokulingana kophawu.

Uxinzelelo lobushushu kwiimodyuli ze-Photovoltaic kunye nezixhobo

Ukungafani kwe-CTE kwiiStacks zeModyuli ezineeLayer ezininzi

Iimodyuli zelanga ziisandwich ezifakwe ilaminate - iglasi eqinisiweyo, i-ethylene-vinyl acetate (EVA) encapsulant, iiseli zesilicon ezinee-metallic interconnects, i-polymeric backsheet, kunye nesakhelo se-aluminium. Umaleko ngamnye une-coefficient eyahlukileyo yokwandiswa kobushushu (CTE). Xa ubushushu butshintsha, ezi laya ziyanwebeka okanye zinciphe ngamanani ahlukeneyo, zivelisa uxinzelelo lwe-shear kunye ne-peel kuyo yonke i-bonded interface.

Itheyibhile 1: Amaxabiso e-CTE kwizixhobo zeModyuli yePV eqhelekileyo

Uxinzelelo lweThermomechanical kwii-Interconnects zeSeli

Umahluko we-CTE phakathi kwe-silicon (2.6 ppm/°C) kunye neribhoni yobhedu (17 ppm/°C) ugxininisa uxinzelelo olujikelezayo ngqo kumgca webhondi ye-solder. Ukugoba okuphindaphindiweyo kuyayikhathaza i-solder alloy, kubangele imifantu eyonyusa ukumelana nochungechunge kwaye kunciphise ukuphuma kwamandla. Amagumbi okujikeleza ngobushushu asebenzisa amazinga okuhamba alawulwayo - ngesiqhelo ukusuka kwi-5°C ukuya kwi-15°C ngomzuzu - ukuphinda olu qokelelo loxinzelelo phantsi kweemeko zelebhu.

Ukubola kwe-Encapsulant kunye ne-Backsheet phantsi koxinzelelo lwe-Cyclic

I-EVA kunye nezinye izinto ezifakwayo zithambisa xa kushushu kakhulu kwaye ziqine xa kushushu kushushu xa kushushu kakhulu ngexesha lovavanyo. igumbi lokuvavanya ibhayisekile eshushuUkujikeleza phakathi kwezi meko kunokubangela ukwahlukana komphezulu weseli okanye kwi-superstrate yeglasi, okudala iindlela zokungena komswakama. Iipolymers zephepha elingasemva ziphantsi koxinzelelo olufanayo, ekugqibeleni ziqhekeke kwaye zonakalise ingqibelelo yokufakelwa kombane yemodyuli.
