Kev ua haujlwm ntawm tes heterojunction ntawm 26.6% ntawm P-hom silicon wafers tau ua tiav.

Lub heterojunction tsim ntawm amorphous / crystalline silicon (a-Si: H / c-Si) interface muaj cov khoom siv hluav taws xob tshwj xeeb, tsim rau silicon heterojunction (SHJ) hnub ci hlwb. Kev sib koom ua ke ntawm ultra-thin a-Si: H passivation txheej tau ua tiav qhov siab qhib-circuit voltage (Voc) ntawm 750 mV. Ntxiv mus, a-Si: H tiv tauj txheej, doped nrog n-hom lossis p-hom, tuaj yeem crystallize rau hauv ib theem sib xyaw, txo cov kab mob cab thiab txhim kho cov neeg nqa khoom xaiv thiab kev sau ua haujlwm.

LONGi Green Energy Technology Co., Ltd.'s Xu Xixiang, Li Zhenguo, thiab lwm tus tau ua tiav 26.6% efficiency SHJ hnub ci cell ntawm P-hom silicon wafers. Cov kws sau ntawv ua haujlwm phosphorus diffusion tau txais cov tswv yim ua ntej thiab siv nanocrystalline silicon (nc-Si: H) rau cov neeg nqa khoom xaiv, ua kom muaj txiaj ntsig zoo ntawm P-hom SHJ hnub ci cell mus rau 26.56%, yog li tsim kom muaj kev ua tau zoo tshiab rau P. -type silicon solar cells.

Cov kws sau ntawv muab cov ncauj lus kom ntxaws txog cov txheej txheem kev txhim kho thiab kev txhim kho photovoltaic. Thaum kawg, kev soj ntsuam poob hluav taws xob tau ua los txiav txim siab txoj hauv kev txhim kho yav tom ntej ntawm P-hom SHJ hnub ci tshuab hluav taws xob.
