Me yasa Flux ke da muhimmanci ga walda na hasken rana?

Gabatarwa

Flux yana da muhimmanci a cikin soldering na photovoltaic lokacin da ake haɗa sel na hasken rana da ribbons. Yana magance oxidation na ƙarfe, inganta jika na solder, da dakatar da oxidation na biyu. Wannan yana tabbatar da ingancin soldering mai ƙarfi da haɓaka amincin dogon lokaci na hasken rana. Ga ainihin dalilin da yasa muke amfani da shi da yadda yake aiki.

Sharewa da Tsabtace Ƙarfe na Surface Oxides

Tsaftacewa da Kunna

Silver paste a kan busbars na cell da copper base na ribbons suna yin oxidation cikin sauƙi a cikin iska. Wannan oxide layer yana toshe solder daga haɗuwa da ƙarfe, yana haifar da rauni ko ƙarya joints. Active agents kamar organic acids a cikin flux suna amsawa da waɗannan oxides kuma suna rushe su. Wannan yana barin tsabtataccen interface mai aiki don soldering.

Rage Surface Tension na Solder

Jika da Yadawa

Narkakken solder yana da ƙarfin saman sama kuma baya yaduwa cikin sauƙi a saman ƙarfe. Surfactants a cikin flux suna rage wannan ƙarfin sosai. Suna haɓaka kwararar solder da wettability, suna barin shi ya bazu da sauri kuma daidai. Wannan yana haifar da cikakken haɗin solder ba tare da voids ba kuma yana ƙarfafa haɗin injiniya.

Hana Oxidation Na Biyu

Kariya Daga Zafin Mai Girma

Soldering yana faruwa a yanayin zafi mai girma. Saman ƙarfe na iya yin oxidation cikin sauƙi a wannan zafin, wanda ke lalata ingancin haɗin. Flux yana shiga ta hanyar samar da iskar gas mai kariya ko fim mai ƙarfi a saman ƙarfe. Wannan shingen yana toshe iska kuma yana hana oxidation na biyu yayin dumama da sanyaya, yana kiyaye haɗin solder mai tsabta.

Ƙarfafa Ƙarfin Soldering

Haɗin Metallurgical da Gudanarwa

Ta hanyar tsaftace saman, inganta jika, da dakatar da iskar oxygen, flux yana taimakawa wajen samar da ƙaƙƙarfan haɗin ƙarfe tsakanin solder da ƙarfe. Wannan a fili yana ƙara ƙarfin jan hankali na haɗin, yana hana shi karyewa. Kyakkyawan soldering kuma yana tabbatar da tafiyar da wutar lantarki cikin santsi tsakanin solar cell da ribbon. Yana rage juriyar tuntuɓar kuma yana ƙara yawan samar da wutar lantarki na module.

Daidaitawa da Bukatun Soldering na PV

Bukatun Tsari na Musamman

Modules na hasken rana suna buƙatar matuƙar daidaito da aminci a soldering. Dole ne flux ɗin da ya dace ya yi aiki a ƙananan zafin jiki don guje wa lalacewar zafi ga cells. Dole ne ya zama marar lalacewa don kada ya cutar da cells ko sauran sassan module. Hakanan yana buƙatar barin ɗan ƙaramin saura. Yawan saura na iya lalata insulation na module ko haifar da lalacewa daga baya. Cimma waɗannan maƙasudai yana kiyaye module yana aiki da kyau a cikin yanayin waje mai tsanani na shekaru.

Ra'ayin Ooitech

Samun ingantaccen sinadarin flux wani muhimmin mataki ne a kowane layin samar da hasken rana. Flux din yana bukatar ya kasance mai aiki sosai don tsaftace busbars da sauri amma kuma ya kasance mai laushi don barin wani abu mai lalata a baya. Lokacin da ake saita tabber stringers don fasahar sel na zamani kamar TOPCon ko HJT, daidaita nau'in flux din daidai da yanayin zafi yana hana fashewar sel da kuma tabbatar da dorewar ingancin module na dogon lokaci.
