Sharaxaad Gaaban:

WeiTai Energy Technology Co., Ltd. waa alaab-qeybiye hormuud ah oo ku takhasusay waferka iyo isticmaalka semiconductor sare.Waxaan u heellannahay inaan siino alaab tayo sare leh, la isku halayn karo, iyo halabuur leh wax-soo-saarka semiconductor,warshadaha photovoltaiciyo qaybaha kale ee la xidhiidha.

Khadkayaga alaabada waxaa ka mid ah alaabada graphite ee dahaarka leh ee SiC/TaC iyo alaabada dhoobada, oo ka kooban agabyo kala duwan sida silikoon carbide, silicon nitride, iyo aluminium oxide iyo iwm.

Bixiye la aamini karo, waxaan fahamsanahay muhiimada ay alaabooyinka u leeyihiin habka wax soo saarka, waxaana naga go'an inaan gaarsiinno alaabada buuxisa heerarka tayada ugu sarreeya si loo fuliyo baahiyaha macaamiisheena.
