Qhov sib txawv ntawm p-type thiab n-type solar panels

Qhov sib txawv ntawm p-type thiab n-type solar panels

Qhov sib txawv tseem ceeb ntawm P-hom thiab N-hom hnub ci vaj huam sib luag yog nyob rau hauv cov khoom siv semiconductor thiab cov yam ntxwv ua haujlwm lawv siv. P-type solar panels siv boron doped P-type silicon wafers ua lub substrate, thaum N-type solar panels siv phosphorus doped N-hom silicon wafers ua substrate. Qhov sib txawv ntawm cov qauv hluav taws xob thiab cov khoom siv hluav taws xob ntawm ob cov ntaub ntawv no ua rau lawv qhov kev sib txawv hauv cov nyhuv photovoltaic thiab efficiency:

N-hom solar panels:

Siv cov khoom siv N-hom silicon, nws muaj ntau dua electron txav thiab tsawg impurities.

Feem ntau muaj ntau dua photoelectric conversion efficiency thiab qis attenuation tus nqi.

Muaj kev tiv thaiv zoo dua rau kev yees duab induced attenuation txhais tau tias kev ua haujlwm ruaj khov nyob rau hauv lub sij hawm ntev illumination.

Siab zog thiab ntau dua conversion efficiency. Raws li cov qauv ntsuas, qhov kev hloov pauv tau zoo tuaj yeem ncav cuag 24.6%, thiab lub hnub ci vaj huam sib luag tuaj yeem ncav cuag 575W.

P-hom solar panels:

Siv cov khoom siv P-hom silicon, cov txheej txheem ntau lawm kuj yooj yim thiab tus nqi qis.

Txawm hais tias qhov kev ua tau zoo tsis zoo li N-hom hnub ci vaj huam sib luag, nws tseem txaus kom tau raws li qhov xav tau ntawm ntau daim ntawv thov.

Lub zog tivthaiv tuaj yeem ncav cuag 550W thiab qhov hloov pauv yog 23.5%.

Tam sim no, cov khoom lag luam tseem ceeb hauv kev lag luam photovoltaic yog P-hom hnub ci hlwb sib raug rau P-hom silicon wafers. Txawm li cas los xij, nrog kev nce qib ntawm thev naus laus zis thiab txo cov nqi, kev lag luam feem ntawm N-hom hnub ci vaj huam sib luag tau maj mam nce. Qhov zoo ntawm N-hom hnub ci vaj huam sib luag ua rau lawv muaj txiaj ntsig zoo hauv cov ntawv thov uas xav tau kev ua haujlwm siab dua thiab kev ua haujlwm ruaj khov dua.
