Kupanga ukadaulo wa crystalline silicon solar cell coating technology

Malangizo a crystalline pakachitsulo chitukuko cha luso cell kumaphatikizanso luso PERT ndi Topcon luso, umisiri awiriwa amaonedwa ngati kutambasuka kwa chikhalidwe kufalitsa njira selo luso, makhalidwe awo wamba ndi passivation wosanjikiza kumbuyo kwa selo, ndipo onse ntchito wosanjikiza doped poly silicon monga kumunda kumbuyo, sukulu nthawi zambiri ntchito mu high-kutentha oxidized oxidized wosanjikiza mu njira ya doLPD ndi doLPD wosanjikiza ndi doLPD wosanjikiza. PECVD, etc. Tubular PECVD ndi Tubular PECVD ndi mbale yathyathyathya PECVD zakhala zikugwiritsidwa ntchito pakupanga kwakukulu kwa maselo a PERC.

Tubular PECVD ili ndi mphamvu yayikulu ndipo nthawi zambiri imagwiritsa ntchito magetsi otsika pafupipafupi makumi angapo a kHz. Kuphulika kwa ma ion ndi zovuta zopumira zimatha kukhudza mtundu wa passivation layer. Lathyathyathya mbale PECVD alibe vuto kulambalala plating, ndipo ali ndi mwayi waukulu ❖ kuyanika ntchito, ndipo angagwiritsidwe ntchito mafunsidwe a doped Si, Si0X, SiCX mafilimu. Choyipa chake ndi chakuti filimu yodzaza imakhala ndi haidrojeni yambiri, yosavuta kuyambitsa matuza a filimu wosanjikiza, yocheperako mu makulidwe a zokutira. LPcvd ❖ kuyanika luso ntchito chubu ng'anjo ❖ kuyanika, ndi mphamvu yaikulu, akhoza kuika wandiweyani polysilicon filimu, koma padzakhala padziko plating kumachitika, mu lpcvd ndondomeko pambuyo kuchotsa mozungulira plating wa wosanjikiza filimuyo ndipo sikupweteka wosanjikiza pansi. Maselo a Topcon opangidwa ndi misa akwanitsa kutembenuza pafupifupi 23%.
