Multijunction hnub ci vaj huam sib luag, tseem hu ua lub hnub ci vaj huam sib luag, yog ib hom photovoltaic hlwb uas yog tsim los ntawm ntau txheej ntawm semiconductors nrog ib tug txawv bandgap uas yuav nqus tau sib txawv wavelengths ntawm lub teeb. Cov tshuab no tso cai rau kev nqus ntawm ntau dua ntawm lub hnub ci spectrum thiab yog li kev hloov pauv ntau dua.
Hom ntau hom hnub ci hnub ci ntau tshaj plaws yog 3-hluav taws xob hnub ci cell, uas yog tsim los ntawm peb txheej ntawm cov khoom siv semiconductor xws li gallium arsenide, indium gallium phosphide, thiab germanium, txhua tus tsim los ntes ntau yam ntawm lub hnub ci. spectrum. Cov txheej sab saum toj absorbs lub teeb pom kev, thaum nruab nrab thiab hauv qab txheej nqus cov infrared thiab ultraviolet lub teeb, feem.
Multijunction solar cells feem ntau yog siv nyob rau hauv cov concentrated photovoltaic (CPV) systems, uas siv lo ntsiab muag los yog tsom iav kom pom tseeb hnub ci mus rau ib tug me me, high-efficiency solar cell. Qhov no tso cai rau txo qis ntawm cov khoom siv semiconductor xav tau, nrog rau kev ua haujlwm siab dua li cov hnub ci vaj huam sib luag vaj huam sib luag.
Zuag qhia tag nrho, kev siv lub hnub ci vaj huam sib luag muaj peev xwm ua kom muaj kev ua tau zoo thiab txo tus nqi ntawm lub hnub ci zog, ua rau nws muaj kev cog lus thev naus laus zis rau yav tom ntej ntawm lub zog tauj dua tshiab.
