Cheebtsam muaj ntau cov roj hlwb xa mus rau cov hlwb hnub ci uas tsis yog ua los ntawm ib qho khoom siv hluav taws xob semiconductor. Muaj ntau yam kev tshawb fawb nyob rau ntau lub teb chaws, vaj huam sib luag hnub ci thiab lawv feem ntau tsis tau muaj kev lag luam, hnub ci vaj huam sib luag feem ntau suav nrog cov hauv qab no: a) cadmium sulfide solar cells b) gallium arsenide solar cells c) tooj liab indium selenium solar cells (tshiab ntau -zoo band ntxi gradient Cu (Hauv, Ga) Se2 nyias zaj duab xis solar cell)
Cu (Hauv, Ga) Se2 yog ib hom hnub ci kev nqus khoom nrog kev ua haujlwm zoo. Nws muaj qhov sib txawv ntawm lub zog sib txawv (lub zog qib sib txawv ntawm cov kab sib txuas thiab pawg valence). Nws tuaj yeem nthuav tawm lub hnub ci zog nqus cov hluav taws xob ntau thiab txhim kho photoelectric hloov dua siab tshiab. ua hauj lwm zoo. Raws li nws, hnub ci vaj huam sib luag nyias-zaj duab xis hnub ci hlwb nrog qhov kev hloov kho tau zoo dua qub dua qub dua li qhov ua tiav silicon nyias-zaj duab xis hnub ci hlwb tuaj yeem tsim. Kev ua tiav ntawm qhov kev xaiv photoelectric hloov dua siab tshiab yog 18%. Ntxiv mus, hnub ci vaj huam sib luag no hom nyias-zaj duab xis hnub ci cell tsis muaj kev ua tau zoo kev cuam tshuam (SWE) tshwm sim los ntawm lub teeb hluav taws xob. Nws cov photoelectric conversion efficiency yog txog 50 ~ 75% siab dua qhov uas coj mus muag nyias-zaj duab xis hnub ci. Hnub ci hlwb muaj qib siab tshaj plaws ntawm kev ua haujlwm photoelectric conversion efficiency nyob hauv lub ntiaj teb.
