Chowunikira cha photovoltaic panel EL ndi mtundu wa chida chomwe chimagwiritsidwa ntchito kuzindikira photovoltaic panel (solar panel). Chimachokera pa mfundo ya electroluminescence ya crystalline silicon. Electroluminescence (el) ndi chinthu chomwe magetsi ogwiritsidwa ntchito amafulumizitsa kuyenda kwa zonyamulira mu Mndandanda wa zinthu za semiconductor pansi pa mphamvu yamagetsi, kusintha gawo la mphamvu ya kinetic kukhala mphamvu yowala. Chowunikira cha photovoltaic panel EL chimagwiritsa ntchito mfundoyi kujambula chithunzi cha crystalline silicon chomwe chili pafupi ndi infrared pogwiritsa ntchito kamera ya infrared yapamwamba kwambiri ndikupeza chithunzi cha selo.
Ntchito yaikulu ya chowunikira cha photovoltaic panel EL ndikuzindikira molondola zolakwika zosiyanasiyana za panel ya photovoltaic, magawo ake ndi monga kusweka kwa chipata, ming'alu, fragment, fragment, braze welding, sintered mesh, black core, Letter boxing, blending, low efficiency chip, Edge etching, PID, attenuation, hot spot attenuation, ndi zina zotero. Zolakwika izi zingakhudze magwiridwe antchito ndi mtundu wa mapanelo a photovoltaic ndipo, ngati sizipezeka ndikuthetsedwa munthawi yake, zitha kusokoneza magwiridwe antchito ndi kukhazikika kwa makina onse opangira mphamvu ya dzuwa.
Kupatula pa kuzindikira molondola zolakwika za mapanelo a PV, chowunikira cha PV panel EL chili ndi zabwino zina. Mwachitsanzo, chili ndi kulondola kwakukulu komanso magwiridwe antchito, chimatha kuzindikira mwachangu komanso molondola malo ndi mtundu wa zolakwika. Kuphatikiza apo, chowunikira cha EL chili ndi mwayi woyesa wowononga kuti sichidzawononga thupi la panel ya photovoltaic yomwe ikuyesedwa kapena kusokoneza magwiridwe ake.
Zithunzi zoyeserera za EL zoyenerera ndi izi:
Nazi zina mwa zolakwika zomwe zimachitika kawirikawiri m'mapanelo a photovoltaic:
Batire yasweka
(1). Zifukwa: gulu la batri linasweka chifukwa cha mphamvu yakunja panthawi yowotcherera kapena kukonzedwa; kutentha kochepa, gulu la batri silinakonzedwenso kutentha, ndipo patatha nthawi yochepa kutentha kwambiri, mwadzidzidzi linayamba kukulirakulira, zomwe zinachititsa kuti pakhale ming'alu; Kutentha kwa batri kumakhala kwakukulu kwambiri panthawi yowotcherera kamodzi kapena serial welding.
(2). Zotsatira za module: zimapangitsa kuti mphamvu ya module ichepe, ndipo zotsatira za hot spot zidzachitika module ikagwira ntchito kwa nthawi yayitali, zomwe zidzakhudza mwachindunji magwiridwe antchito a batri mpaka module itayaka ndi kutayidwa.
(3). Njira zodzitetezera: pakuwotcherera kapena kukonza kuti tipewe kukhudzidwa ndi mphamvu zakunja pa batire, pakuwotcherera batire imodzi kapena tandem kuti itenthetsedwe, kutentha kwa chitsulo chamagetsi kuyenera kukwaniritsa zofunikira zaukadaulo pakupanga.
Chipata Chosweka
(1). Mawonekedwe a zithunzi za EL: Kuchokera pachithunzi cha El, pali mizere yoyima pakati pa mizere iwiri ya gridi, ndipo pali mizere yakuda pamzere waukulu wa gridi wa selo. Nthawi yomweyo, mphamvu yofooka ya kuwala kapena kusawala pa grating yopyapyala kumachitika makamaka chifukwa cha maselo osalumikizana.
(2). Zifukwa: Chifukwa chachikulu cha kuwonongeka kwa chipata ndi malo osweka a chipata chosalala komanso kutayika kwa chipata chosalala, zomwe zimapangitsa kuti mzere waukulu wa chipata ukhale wosalala ndipo mzere wosalala wa chipata chosalala sungapange kuzungulira. Nthawi yomweyo, gridi si yokhazikika yolumikizira kapena yosindikiza bolodi la batri, khalidwe losindikiza pazenera silili bwino kapena magawo osindikizira pazenera sakukhazikitsidwa bwino, kudula kwa silicon kosagwirizana, cholakwika.
(3). Zotsatira za module: ngakhale kuchepetsa kugwira ntchito bwino kwa module ya photovoltaic, sikwabwino kusonkhanitsa mphamvu yamagetsi.
(4). Njira zodzitetezera: kukhazikitsa magawo oyenera osindikizira pazenera, kusonkhanitsa zinthu pazenera, kukhazikitsa njira zogwiritsira ntchito pazenera, kuyang'anira nthawi yeniyeni RS kungachepetse kwambiri kusweka kwa chipata chosindikizira pazenera, nthawi yomweyo ikhoza kukhala ndi makina osonkhanitsira okha kuti aziwunika pa intaneti.
Chipu chakuda
(1). EL imaging imaging: mu chithunzi cha EL, mutha kuwona mabwalo ozungulira omwe amawala pang'onopang'ono kuchokera pakati mpaka m'mphepete mwa selo. Gawo lina la batri ndi lakuda ndipo chithunzicho chimawoneka chofooka kapena chosawala. Izi zimapanga malo ophatikizika okhala ndi malo okhuthala, pankhani ya mphamvu, pakati pa batri pamawoneka malo akuda.
(2). Pakupangidwa kwa kristalo ya ndodo ya silicon, kuchuluka kwa silicon rod komwe kumagawika kwambiri kumagwirizana mwachindunji ndi kusungunuka kwa mpweya, ndipo zinthu za silicon zimadetsedwa mosiyanasiyana, zomwe zimapangitsa kuti gawo la batri lisinthe kukhala lakuda. Nthawi yomweyo, chifukwa cha kufupikitsa nthawi yolimba yolunjika, kutulutsidwa kwa kutentha kobisika komanso kufananiza kutentha kwa kusungunuka sikokwera kwambiri, liwiro la kukula kwa kristalo limakulitsidwa, ndipo chifukwa chachikulu cha vuto la kusokonekera kwamkati ndi kutentha kwambiri.
(3). Kukhudzidwa kwa gawo: pambuyo poti chip chakuda chaonekera mu gawo, kuthamanga kwa nthawi yayitali kumayambitsa kuwonongeka kwa kutentha, pamene curve ya test component IV, curve ikuwoneka ngati makwerero, kuthamanga kwa nthawi yayitali kumayambitsa kuchepa kwa mphamvu yotulutsa gawo.
(4). Njira zodzitetezera: sinthani moyenera kuchuluka kwa coagulation coefficient ndi kusungunuka kwa mpweya mu ndodo ya silicon kuti mupewe kuipitsa zinthu za silicon.
Chip yakuda ya Short Circuit (chip yakuda yopanda short circuit)
(1). Makhalidwe a kujambula kwa EL: ma module a photovoltaic pamalo enaake adzawoneka chidutswa chimodzi kapena zingapo za Batri yakuda kwambiri.
(2). Zoyambitsa: kufupika kwa ma electrode abwino ndi oipa, kulowetsa m'mbuyo pakati pa ma electrode abwino ndi oipa a junction box diode, kulumikizana kolakwika ndi kulowetsa m'malo enieni pakati pa ma electrode abwino ndi oipa, ndi zina zotero, ma cell unit osakanikirana osagwira ntchito bwino, ndi ma silicon wafers abwino kapena ma wafers amtundu wa N amagwiritsidwa ntchito molakwika. Kusowa kwa ma PN junctions ndi chimodzi mwa zifukwa zomwe EL imaging imakhala yakuda kwathunthu.
(3). Zotsatira za gawo: kuchuluka kwa kudzaza ndi mphamvu yotulutsa ya gawolo zidzakhudzidwa kwambiri. Mphamvu yotulutsa ya gawo lonse la PV imachepetsedwa, ndipo mphamvu yayikulu ya IV characteristic curve imachepetsedwa.
(4). Zosamala: batire ikalumikizidwa, solder imasiyidwa m'mphepete kuti ipewe malo olumikizira solder kutentha kochepa. Pambuyo poti cholumikiziracho chayikidwa laminated, yang'anani ngati diode ya junction box yalumikizidwa komanso ngati waya wotsogola walumikizidwa molakwika.
Mwachidule, chowunikira cha photovoltaic panel EL ndi chida chofunikira chodziwira, mu dongosolo la mphamvu ya dzuwa chimagwira ntchito yofunika kwambiri. Sichingongowonjezera mphamvu yosinthira magetsi, kuchepetsa ndalama, kulimbikitsa chitukuko cha mphamvu zongowonjezwdwanso, komanso kuonetsetsa kuti makina opangira magetsi a dzuwa ndi olimba komanso ogwira ntchito bwino.
