Kwimveliso echanekileyo yeeseli zelanga ze-perovskite kunye nezixhobo ze-optoelectronic, ukuchaneka kwenkqubo yokugquma kumisela ngokuthe ngqo ukusebenza kakuhle kokuguqulwa kwe-photoelectric kweemveliso. Njengesixhobo esisisiseko sezixhobo zokugquma, ipharamitha yoxinano lwegranite (ngesiqhelo yi-2600-3100kg/m³) ayisiyonto nje ebonakalayo kodwa yinto ephambili echaphazela kakhulu uzinzo, ukumelana nokungcangcazela kunye nokuthembeka kwexesha elide kwezixhobo. Oku kulandelayo luhlalutyo lonxibelelwano lwangaphakathi oluvela kwiinkalo ezine eziphambili.
Ulwakhiwo oluxineneyo lwesiseko esizinzileyo "esingenakususwa"
Iingubo zePerovskite zinemfuno ephezulu kakhulu yokuba umphezulu we-substrate ube tyaba (Ra≤0.5μm), kwaye naluphi na ufuduko lwesiseko lunokukhokelela kubukhulu obungalinganiyo bengubo okanye iziphene zemingxuma. I-Granite enobunzima obuyi-≥3100kg/m³ inokwenza ubunzima obunamandla kakhulu ngenxa yesakhiwo sayo seeminerali esidityaniswe ngokusondeleyo ngaphakathi. Kumgca othile wemveliso yebhetri ye-TOPCon perovskite tandem, emva kokwamkela isiseko segranite esinobunzima obuphezulu, ukuphambuka kobukhulu bengubo kwezixhobo kwehle ukusuka kwi-±15nm ukuya kwi-±3nm phantsi kwendawo yokungcangcazela koomatshini okuphindaphindekayo (50-200Hz), okuphucula kakhulu ukuhambelana kwe-current-voltage current current current current current.
2. Isiphumo esihle sokunxibelelana phakathi koxinano kunye nokuncitshiswa kokungcangcazela
Ngexesha lenkqubo yokugquma, intshukumo yesantya esiphezulu sentloko yokugquma echanekileyo (enesantya esithe tyaba esidlula i-800mm/s) inokubangela ukurhawuzelelwa kwizixhobo. Izifundo zibonisa ukuba xa kukho ukunyuka kwe-10% koxinano lwegranite, ukusebenza kakuhle kokuncitshiswa kokungcangcazela kunokwandiswa nge-18%. Xa uxinano lufikelela kwi-3100kg/m³, imvamisa yayo yendalo ingaba phantsi njenge-12Hz, nto leyo ethintela ngokufanelekileyo uluhlu olubuthathaka lokungcangcazela (20-50Hz) lwezixhobo zokugquma. Uvavanyo lweqela lophando laseJamani lubonise ukuba isiseko segranite esixineneyo soxinano oluphezulu sonyuse ukufana kobukhulu befilimu yenkqubo yokugquma i-perovskite ngama-27% kwaye sanciphisa izinga lesiphene ngama-40%.
3. Ukusebenza kozinzo lobushushu oluphuculweyo oluphezulu
Izinto zePerovskite zinobuthathaka kakhulu kutshintsho lobushushu. Utshintsho lwe-0.1℃ lunokubangela ukuphambuka kwelatisi. Ngenxa yokusondela kwesithuba seathomu ngaphakathi, i-coefficient yokwandiswa kobushushu begranite enoxinano oluphezulu (4-6×10⁻⁶/℃) iphantsi ngama-30% kunezo zezixhobo eziqhelekileyo. Kwinkqubo yokufakelwa (100-150℃), isiseko esinoxinano oluphezulu sinokulawula ukuguquguquka kobushushu bezinto eziphambili zezixhobo ngaphakathi kwe-±0.5μm, ukuqinisekisa ukuba ugqubuthelo lugcina ulungelelwano oluncinci emva konyango lobushushu obuphezulu kwaye luphephe ukuqhekeka kogqubuthelo okubangelwa kuxinzelelo lobushushu.
4. Isiqinisekiso sokusebenza ixesha elide "sokulwa nokudinwa"
Izixhobo zokugquma ze-perovskite zisebenza ngaphezu kweeyure ezili-16 ngosuku ngokomyinge, kwaye isiseko kufuneka simelane noxinzelelo oluqhubekayo loomatshini. I-Granite enobunzima obuyi-3100kg/m³ inamandla okucinezela angama-≥200MPa kwaye ukumelana kwayo nokuguguleka kuphindwe kahlanu kunentsimbi eqhelekileyo. Idatha yokulinganisa yokwenyani yefektri ethile ye-perovskite module eyenziwe ngobuninzi ibonisa ukuba emva kokusebenza ngokuqhubekayo iminyaka emithathu, ukuchaneka kokubeka umatshini wokugquma onesiseko se-granite esinobunzima obuphezulu kwehle nge-0.8% kuphela, ngelixa eso sezixhobo esinesiseko esinobunzima obuphantsi sehle nge-3.2% ngelo xesha linye, nto leyo enciphisa kakhulu iindleko zokugcinwa kwezixhobo kunye nomngcipheko wexesha lokungasebenzi.
Isiphelo: Ukukhetha uxinano oluphezulu kuthetha ukukhetha ukusebenza okuphezulu
Ukususela ekuchanekeni kwe-nanoscale coating ukuya ekusebenzeni okuzinzileyo kwexesha elide kwemigca yemveliso, uxinano lwe-granite luye lwaba yinto ephambili echaphazela ukusebenza kwezixhobo zokugquma ze-perovskite. Kumashishini avelisa izinto afuna ukusebenza kakuhle nomgangatho, ukukhetha iziseko ze-granite ezikumgangatho ophezulu ezinomthamo we-≥3100kg/m³ (ezifana neemveliso eziqinisekisiweyo ze-ZHHIMG®) akuqinisekisi nje kuphela inkqubo yangoku kodwa kukwamele utyalo-mali olucwangcisiweyo lokuphucula amandla kwixesha elizayo.
