Amathuba okwandisa isizinda anqunyelwe
Izinguquko zobuchwepheshe ekukhiqizweni kwamaphaneli elanga zikhulisa isidingo sesiliva, okuyisenzakalo esijulisa ukushoda ekuhlinzekweni kwensimbi eyigugu, kuyilapho kunethuba elilinganiselwe emkhathizwe lokuthola izimayini ezengeziwe, kubhala i-Bloomberg.
Isiliva, ngendlela yokunamathisela, isetshenziselwa ungqimba olusebenzayo ngaphambili nangemuva kwamaseli elanga e-silicon. Kodwa umkhakha usuqala ukukhiqiza izinhlobonhlobo ezisebenza kahle kakhulu zamaseli asebenzisa insimbi eningi, futhi lokhu kuzokwengeza ekusetshenzisweni okuvele kukhula.
Amandla elanga asakha ingxenye encane yesidingo esiphelele sesiliva, kodwa siyakhula. Ngokombiko we-The Silver Institute, izoba ngu-14% wokusetshenziswa kulo nyaka, isuka cishe ku-5% ngo-2014. Okuningi kwalokho kukhula kuvela eChina, okulindeleke ukuthi ifake amanye ama-solar panels kulo nyaka. , kune-US.
Ngokusho kwe-BloombergNEF, i-emitter ejwayelekile neseli yokuxhumana ngemuva kungenzeka idlulwe eminyakeni emibili kuya kwemithathu ezayo ngokuthintana kwe-tunnel oxide passivated kanye ne-heterojunction structure. Nakuba esimweni sokuqala amaseli adinga cishe amamiligremu angu-10 esiliva ngewathi ngayinye, amaseli e-tunnel oxide adinga ama-milligram angu-13 namaseli e-heterojunction amamiligremu angu-22.
Ngesikhathi esifanayo, ukunikezwa kuqala ukubukeka kunomkhawulo. Bekuyisicaba ngonyaka owedlule, yize isidingo sikhuphuke cishe ngengxenye yesihlanu, kusho imininingwane yeSilver Institute. Kulo nyaka, ukukhiqizwa kulindeleke ukuthi kukhuphuke ngo-2%, kanti ukusetshenziswa kwezimboni kulindeleke ukuthi kukhule ngo-4%.
Inkinga yabathengi besiliva ukuthi akulula neze ukukhulisa ukunikezwa, uma kubhekwa ukuthi zimbalwa kangakanani izimayini ezikhona ngokuyinhloko zokukhiqiza isiliva. Cishe amaphesenti angama-80 ensimbi atholakala kumaphrojekthi okumba umthofu, i-zinc, ithusi negolide, lapho isiliva liwumkhiqizo okhiqizwayo.
Futhi endaweni lapho izinkampani zezimayini zingasazimisele ngokuzibophezela kumaphrojekthi amasha amakhulu, amamajini aphansi esiliva uma kuqhathaniswa nezinye izinsimbi eziyigugu nezimboni zisho ukuthi amasiginali wamanani amahle awanele ukukhulisa umkhiqizo. Ngisho namaphrojekthi asanda kugunyazwa, ukukhiqizwa kungase kungaqali iminyaka eyishumi ngaphambi kwesikhathi.
Ngenxa yalokhu, umkhakha welanga ungaqeda u-85-98% wemithombo yesiliva yomhlaba ngo-2050, ngokocwaningo olwenziwe yiNyuvesi yaseNew South Wales. Inani lesiliva elisetshenziselwa ukukhiqiza iseli elilodwa lizokhula futhi lingase lithathe cishe iminyaka emihlanu kuya kweyi-10 ukubuyela emazingeni amanje, ulinganisela uBrett Hallam, omunye wababhali balolu cwaningo.
Kodwa-ke, izinkampani zelanga zaseShayina zihlola ngenkuthalo ukuthi kungenzeka yini ukusebenzisa ezinye izindlela ezishibhile, njengethusi eliphehliwe, nakuba kuze kube manje imiphumela ixutshwe. Ubuchwepheshe obusebenzisa izinsimbi ezishibhile kakade sebuthuthuke ngokwanele ukuthi bungakwazi ukukhiqizwa ngobuningi ngokushesha ngemva kokukhuphuka kwamanani esiliva, kusho uZhong Baosheng, usihlalo wenkampani enkulu kunazo zonke emhlabeni eyakha amaphaneli elanga iLongi Green Energy Technology Co.
Isiliva njengamanje lihweba cishe ku-$22.70 nge-troy ounce ngayinye. Intengo yehle cishe ngo-5% kulo nyaka kodwa isalokhu ingaphezulu kakhulu kwezinga eyayikulo ngaphambi kwe-spike ngo-2020 njengoba ubhubhane lukhulisa isidingo.
"Ukushintshwa kwesiliva kuzodala inzalo ethe xaxa uma ibiza u-$30 i-troy ounce, hhayi ama-$22-$23," kusho uPhilip Klapwijk, umqondisi ophethe wenkampani ezinze eHong Kong iPrecious Metals Insights Ltd. kanye nomunye wababhali beSilver Institute. umbiko. Ngeke kube khona "isimo sosuku lwembubhiso" lapho siphelelwa khona isiliva, kodwa "imakethe izophinde ilinganise ngentengo ephezulu," ukholelwa ukuthi.
