Tam sim no, tus nqi ntau ntawm lub hnub ci hluav taws xob tsim hluav taws xob yog qhov dav heev. Cov chaw nyob me me feem ntau yog li ntawm 10,000 txog 50,000 yuan, thaum lub lag luam loj lossis kev lag luam muaj peev xwm ncav cuag ntau pua txhiab lossis ntau lab yuan. Tus nqi tshwj xeeb yog cuam tshuam los ntawm qhov system muaj peev xwm, cov khoom siv zoo, thiab kev teeb tsa tsis yooj yim.
Nrog rau kev txhim kho thev naus laus zis, tus nqi ntawm lub hnub ci hluav taws xob tsim hluav taws xob txuas ntxiv poob qis. Hauv xyoo 2023, tus nqi nruab nrab ntawm lub ntiaj teb ntawm kev tsim hluav taws xob photovoltaic tau nqis mus rau $ 0.03-0.05 ib kilowatt-teev, nce mus txog qib ntawm fossil fuels. Txawm li cas los xij, kev lag luam tseem ntsib cov teeb meem xws li kev tsis sib haum xeeb hauv cov cuab yeej siv hluav taws xob, kev txwv kev sib txuas ntawm kab sib chaws, thiab kev nqis peev loj. Nyob rau hauv lub neej yav tom ntej, kev siv dav dav ntawm cov roj teeb uas muaj peev xwm ua tau zoo (xws li roj teeb heterojunction thiab perovskite roj teeb) thiab cov kev tswj xyuas lub zog ntse yuav txhawb nqa ntau daim ntawv thov kev siv hluav taws xob hnub ci.
