Nga waahanga hua
1、Te taumata teitei o te tiaki i te taiao: Ka taea te whakatutuki i te tuhi maataki me te kore e whakamahi i nga turanga waro penei i te TMAH.
2, He iti te utu o te hanga: Ma te whakamahi i te NaOH/KOH hei wai etching, he iti ake te utu i te whakakorikori waikawa me te tukanga etching.
3 、 Te kaha o te mahi whakairo: Ka whakatauritea ki te whakakoi waikawa me te tukanga etching, kua piki ake te pai o te pākahiko i te 0.15%.
Nga Tono Hua
1、 Ko te tikanga tenei hua e tika ana mo nga tukanga pākahiko Perc me Topcon;
2, He pai mo nga tioata kotahi o 210, 186, 166, me te 158 nga whakaritenga.
Nga tohutohu mo te whakamahi
1, Tāpirihia te nui o te kawakore ki roto i te tank (1.5-4% i runga i te ōwehenga rōrahi KOH/NAOH)
2, Tāpirihia he rahinga tika o tenei hua ki roto i te tank (1.0-2% i runga i te ōwehenga rōrahi)
3, Whakawerahia te wai tank whakakoi ki te 60-65°C
4, Whakanohia te wafer silicon me te tuara o te PSG kua tangohia ki roto i te tank whakakoi, ko te wa tauhohenga he 180s-250s
5、 Te mate taimaha e taunakihia ana mo ia taha: 0.24-0.30g (210 puna angiangi, ka hurihia etahi atu puna ki nga waahanga rite) kotahi me te polycrystalline PERC pūtau solar
Whakatupato
1, Me penapena nga taapiri mai i te marama.
2、Ki te kore e puta te raina whakaputa, me whakakiia te wai me te whakaheke ia 30 meneti.Mena karekau he hanga mo te neke atu i te 2 haora, ka tūtohu kia whakahekehia me te whakakii ano i te wai.
3 、Ko te whakakore i te raina hou e hiahia ana ki te hoahoa DOE i runga i ia mahinga o te raina whakaputa ki te whakatutuki i nga mahi whakarite, na reira ka nui ake te pai.Ko te tukanga e taunaki ana ka taea te tuku ki te patuiro.
