Cov hlwb photovoltaic tau dhau los ua peb tiam neeg ntawm kev txhim kho thev naus laus zis:
Thawj Tiam: Crystalline Silicon Technology
Qhov no yog raws li silicon ua cov khoom siv tseem ceeb, uas muaj cov thev naus laus zis xws li BSF, PERC, TOPCon, HJT, thiab IBC.
Tiam Thib Ob: Kev Siv Tshuab Thin-Film
Cov ntaub ntawv xws li Copper Indium Gallium Selenide (CIGS), Cadmium Telluride (CdTe), thiab Gallium Arsenide (GaAs), cov hlwb nyias nyias tau tawm tsam kom sib tw nrog crystalline silicon vim tias nws ua haujlwm tau zoo dua thiab tus nqi siab (ntau dua $ 2 billion ib GW ntawm kev nqis peev). Tam sim no, lawv cov feem ntawm kev ua lag luam tsawg dua 5%.
Tiam Thib Peb: Perovskite thiab Organic Solar Cells
Vim tias muaj cov roj teeb perovskite solar cells ntau heev, tiam neeg no tau loj hlob sai heev nyob rau xyoo tas los no. Nws yog ib qho thev naus laus zis zoo uas yuav dhau cov roj teeb crystalline silicon ua qhov kev tshawb pom tshiab hauv photovoltaics.
Kev nce qib hauv kev ua haujlwm ntawm Photovoltaic Cell Conversion Efficiency
Piv rau cov crystalline silicon, cov hlwb perovskite muaj kev ua haujlwm zoo dua thiab cov nqi tsim khoom qis dua. Cov hlwb perovskite ib leeg thiab tandem muaj kev ua haujlwm zoo ntawm 33% thiab 45%, raws li, dhau qhov siab tshaj plaws rau crystalline silicon. Kev lag luam, tus nqi mus sij hawm ntev ntawm cov modules perovskite ib leeg yog kwv yees li ntawm 0.5–0.6 RMB / W, qis dua li crystalline silicon, ua rau nws yog qhov chaw tseem ceeb rau kev txhim kho photovoltaic yav tom ntej.
Txawm hais tias cov hlwb perovskite tseem nyob rau theem pib ntawm kev lag luam, ob lub tuam txhab crystalline thiab amorphous silicon tab tom nqis peev rau hauv qhov kev lag luam no. Ntau qhov chaw ntawm peev kuj tau nkag mus rau hauv kev ua lag luam, ua rau muaj kev txaus siab dav dav thiab ua kom kev lag luam sai dua.
Cov Teeb Meem thiab Txoj Kev Mus Rau Kev Lag Luam
Cov hlwb Perovskite ntsib teeb meem ntsig txog kev ruaj khov thiab cov txheej txheem tsim khoom, uas yuav tsum tau daws kom ua tiav kev tsim khoom loj. Cov kab tsim khoom sim tam sim no tseem nyob rau theem sim. Cov teeb meem tseem ceeb suav nrog kev txhim kho kev ruaj khov thiab kev hloov pauv zoo dua los ntawm cov ntaub ntawv zoo dua thiab cov txheej txheem. Cov kev tsim kho tshiab tseem ceeb, xws li cov ntaub ntawv tiv taus dej thiab roj, cov khoom ntxiv los txhim kho kev ruaj khov, cov txheej txheem passivation, thiab cov khoom siv siab heev, yog qhov tseem ceeb rau kev kov yeej cov teeb meem no. Kev tawg ua tej yam hauv cov cheeb tsam no yuav tsav kev siv lag luam, nrog rau cov khoom faib tawm PV thiab cov khoom lag luam rau cov neeg siv khoom yuav ua haujlwm ua cov xwm txheej thov thawj zaug.
Tandem Cells: Ib qho tseem ceeb rau kev qhib kev ua haujlwm zoo
Piv rau cov hlwb ib leeg, cov qauv tandem muab kev ua haujlwm zoo dua. Ntawm cov no, silicon-perovskite plaub-terminal tandem hlwb tau nce qib sai dua rau kev lag luam vim lawv cov qauv yooj yim dua thiab cov txiaj ntsig zoo rau cov hlwb crystalline silicon. Ob-terminal tandem hlwb, thaum nyuaj dua, ua kom cov qauv hlwb yooj yim dua thiab zoo dua rau kev sib txuas nrog HJT thev naus laus zis. Cov hlwb tandem puv-perovskite sawv cev rau qhov kev daws teeb meem zoo tshaj plaws, muab kev ua haujlwm zoo dua thiab cov nqi qis dua.
Kev Sib Tw thiab Kev Koom Tes
Cov tuam txhab tsim cov amorphous silicon, xws li GCL Optoelectronics, Xinnano, thiab Microquanta, tau ua tus thawj coj hauv kev tsim cov perovskite, lub hom phiaj yog nkag mus rau hauv kev lag luam PV los ntawm cov thev naus laus zis tshiab no. Lub caij no, cov tuam txhab crystalline silicon ib txwm tau nkag mus rau hauv kev sib tw tom qab me ntsis, tsom mus rau cov thev naus laus zis tandem los txhim kho kev ua haujlwm ntawm cov hlwb crystalline silicon uas twb muaj lawm.
Cov tuam txhab amorphous silicon ntsib teeb meem nyiaj txiag thiab tej zaum yuav ua kom nrawm dua kev tsim cov plaub-terminal tandem cells kom ntseeg tau tias muaj txiaj ntsig sai dua. Ntawm qhov tod tes, cov tuam txhab crystalline silicon yuav nrhiav kev yuav cov tuam txhab perovskite tshiab los koom ua ke lawv cov kev nce qib, ua rau kev sib koom ua ke ntawm kev lag luam.
Txawm hais tias lawv sib tw los xij, cov tuam txhab crystalline thiab amorphous silicon muaj lub hom phiaj zoo sib xws: txhawb kev lag luam ntawm perovskite thev naus laus zis. Kev sib koom tes ua haujlwm yuav tsum tau ua kom tiav hauv lub sijhawm luv luv, vim tias ob tog ua haujlwm kom paub txog tag nrho cov peev xwm ntawm kev siv perovskite hauv kev lag luam photovoltaic.
