Nws txhim kho kev ua haujlwm los ntawm kev txhim kho cov neeg nqa khoom xaiv thiab tuaj yeem sib koom ua ke nrog cov kab tsim khoom crystalline silicon uas twb muaj lawm, txo cov nqi thiab cov teeb meem kev siv tshuab rau kev txhim kho kev lag luam.
HJT (Heterojunction nrog Intrinsic Thin-Layer) Technology
Cov Ntsiab Cai & Cov Nta:
HJT muab cov crystalline silicon nrog cov thev naus laus zis nyias nyias los tsim cov qauv sib npaug ob sab. Nws siv cov yeeb yaj kiab silicon amorphous intrinsic thiab cov yeeb yaj kiab silicon amorphous doped rau ob sab ntawm N-type silicon wafer, tsim ib qho PN junction. Cov oxides conductive pob tshab (TCOs) pab txhawb kev conductivity.
Cov ntawv thov:
Cov hlwb HJT, nrog kev ua haujlwm zoo thiab kev puas tsuaj tsawg los ntawm lub teeb (LID), yog qhov tsim nyog rau cov ntawv thov kev ua haujlwm siab xws li cov kab ke PV ru tsev, agrivoltaics, thiab cov photovoltaics sib xyaw ua ke hauv tsev (BIPV).
Qhov Tseem Ceeb & Cov Zoo:
Cov thev naus laus zis HJT muaj kev ua haujlwm zoo tshaj 24%, nrog rau lub peev xwm tshaj 30%. Nws cov txiaj ntsig suav nrog kev tiv taus LID thiab PID (kev puas tsuaj uas ua rau muaj kev puas tsuaj), cov coefficients kub qis, bifaciality siab, thiab kev ua haujlwm zoo dua thaum tsis muaj teeb pom kev zoo. Cov yam no ua kom muaj zog ntau dua thiab muaj txiaj ntsig zoo dua li cov hlwb PERC ib txwm muaj.
Cov Cell Hnub Ci Perovskite
Cov Ntsiab Cai & Cov Nta:
Cov roj teeb hnub ci Perovskite siv cov organic-inorganic halide semiconductors nrog cov qauv ABX3 ua cov khoom siv nqus lub teeb. Lawv qhia txog cov coefficients nqus tau siab, ntev ntawm cov neeg nqa khoom diffusion, thiab cov bandgaps hloov kho tau.
Cov ntawv thov:
Cov hlwb Perovskite muaj ntau yam siv tau, siv tau rau hauv cov chaw tsim hluav taws xob loj, BIPV, thiab kev tsim hluav taws xob sab hauv tsev uas tsis muaj teeb pom kev zoo.
Qhov Tseem Ceeb & Cov Zoo:
Cov hlwb Perovskite tau ua tiav qhov ua tau zoo hauv chav kuaj mob txog li 25.7%, nrog rau qhov chaw rau kev txhim kho ntxiv. Lawv muab cov nqi khoom siv qis, kev tsim khoom kub qis, thiab kev ua tau zoo heev hauv qhov chaw tsaus ntuj, ua rau lawv yog qhov kev daws teeb meem zoo rau ntau yam kev xav tau hluav taws xob.
IBC (Interdigitated Back Contact) Kev Siv Tshuab
Cov Ntsiab Cai & Cov Nta:
IBC tshem tawm cov electrodes sab pem hauv ntej los ntawm kev muab txhua qhov kev sib cuag rau sab nraub qaum ntawm lub cell, tshem tawm cov teeb meem nqus lub teeb thiab txhim kho kev hloov pauv zoo.
Cov ntawv thov:
Cov hlwb IBC yog qhov nyiam dua hauv cov lag luam zoo tshaj plaws, xws li cov tshuab ru tsev siab heev thiab cov kev daws teeb meem BIPV uas sib xyaw ua ke zoo nkauj.
Qhov Tseem Ceeb & Cov Zoo:
Cov thev naus laus zis IBC ua rau muaj kev ua haujlwm zoo dua thiab zoo nkauj dua. Nws cov txiaj ntsig suav nrog kev tiv thaiv series tsawg dua, kev kam rau duab ntxoov ntxoo zoo dua, thiab kev hloov pauv hluav taws xob zoo heev, ua rau nws zoo tagnrho rau cov ntawv thov uas muab qhov tseem ceeb rau kev ua haujlwm zoo thiab kev tsim qauv.
Xaus lus
Txhua yam thev naus laus zis ntawm lub hnub ci no ua lub luag haujlwm tseem ceeb hauv kev txhim kho kev ua haujlwm zoo, txo cov nqi, thiab nthuav dav qhov kev siv photovoltaics. Thaum cov thev naus laus zis no loj hlob thiab nthuav dav, lawv yuav ua rau lub zog hnub ci ua haujlwm zoo dua, ua kom nrawm hloov mus rau lub zog huv thiab daws cov teeb meem huab cua.
