Menyetla ea ho eketsa ho ntšoa e fokotsehile
Liphetoho tsa theknoloji tlhahisong ea liphanele tsa letsatsi li eketsa tlhokahalo ea silevera, e leng ntho e ntseng e tebisa khaello ea phepelo ea tšepe ea bohlokoa, ha ho ntse ho e-na le monyetla o fokolang oa ho boloka merafo e eketsehileng, ho ngola Bloomberg.
Silevera, ka mokhoa oa pente, e sebelisoa bakeng sa lesela la conductive ka pele le ka morao ho lisele tsa letsatsi tsa silicon. Empa lefapha le se le ntse le qala ho hlahisa mefuta e mengata e sebetsang ea lisele tse sebelisang tšepe e ngata, 'me sena se tla eketsa tšebeliso e seng e ntse e eketseha.
Matla a letsatsi a ntse a etsa karolo e batlang e le nyenyane ea tlhokahalo eohle ea silevera, empa e ntse e hōla. Ho ea ka tlaleho ea The Silver Institute, e tla etsa 14% ea tšebeliso ea selemo sena, ho tloha ho hoo e ka bang 5% ka 2014. Boholo ba khōlo eo bo tsoa Chaena, e lebeletsoeng ho kenya lisebelisoa tse ngata tsa letsatsi selemong sena. , ho feta US.
Ho ea ka BloombergNEF, emitter e tloaelehileng e emitter le sele ea mokokotlo e ka 'na ea haptjoa lilemong tse peli ho isa ho tse tharo tse tlang ke tunnel oxide passivated contact le heterojunction structures. Le hoja tabeng ea pele lisele li hloka hoo e ka bang limiligrama tse 10 tsa silevera ka watt, lisele tsa tunnel oxide li hloka limiligrama tse 13 le lisele tsa heterojunction 22 milligrams.
Ka nako e ts'oanang, phepelo e qala ho shebahala e lekanyelitsoe. E ne e bataletse selemong se fetileng, leha tlhokeho e ile ea nyoloha ka hoo e ka bang karolo ea bohlano, ho bonts'itse data ea Silver Institute. Selemong sena, tlhahiso e lebelletsoe ho eketseha ka 2%, ha ts'ebeliso ea indasteri e lebelletsoe ho hola ka 4%.
Bothata ba bareki ba silevera ke hore ho hang ha ho bonolo ho eketsa phepelo, ho latela hore na ke merafo e fokolang hakae e leng teng haholo-holo bakeng sa tlhahiso ea silevera. Hoo e ka bang 80% ea phepelo ea tšepe e tsoa mererong ea merafo ea loto, zinki, koporo le khauta, moo silevera e leng sehlahisoa.
'Me tikolohong eo lik'hamphani tsa merafo li seng li ikemiselitse ho etsa merero e mecha e meholo, likhahla tse tlase tsa silevera ha li bapisoa le lirafshoa tse ling tsa bohlokoa le tsa indasteri li bolela hore matšoao a theko e ntle ha a lekana ho matlafatsa tlhahiso. Leha ho na le merero e sa tsoa amoheloa, tlhahiso e kanna ea se qale lilemo tse leshome qalong.
Ka lebaka leo, karolo ea letsatsi e ka fokotsa 85-98% ea mehloli ea silevera ea lefats'e ka 2050, ho latela phuputso e entsoeng ke Univesithi ea New South Wales. Chelete ea silevera e sebelisoang ho hlahisa sele e le 'ngoe e tla eketseha' me e ka nka lilemo tse ka bang hlano ho isa ho tse 10 ho khutlela maemong a hona joale, ho hakanya Brett Hallam, e mong oa bangoli ba thuto.
Leha ho le joalo, lik'hamphani tsa letsatsi tsa Chaena li ntse li hlahloba ka mafolofolo monyetla oa ho sebelisa mekhoa e meng e theko e tlaase, e kang koporo e entsoeng ka masenke, le hoja ho fihlela joale liphello li tsoakane. Theknoloji e sebelisang litšepe tse theko e tlaase e se e tsoetse pele ka ho lekaneng hore e ka kenngoa tlhahisong ea bongata hang ka mor'a hore litheko tsa silevera li nyolohe, ho boletse Zhong Baosheng, molula-setulo oa moetsi oa liphanele tsa letsatsi tse kholo ka ho fetisisa lefatšeng Longi Green Energy Technology Co.
Silver hajoale e rekisoa hoo e ka bang $22.70 ka troy ounce. Theko e theohile ka hoo e ka bang 5% selemong sena empa e ntse e le kaholimo ho boemo boo e neng e le ho bona pele ho spike ka 2020 ha seoa se ntse se eketsa tlhokahalo.
"Ho nkeloa sebaka ha silevera ho tla hlahisa phaello e ngata ha e ka ba $30 troy ounce, eseng $22- $23," ho boletse Philip Klapwijk, motsamaisi ea ka sehloohong oa boeletsi ba Hong Kong Precious Metals Insights Ltd. le e mong oa bangoli ba Silver Institute. tlaleha. Ho ke ke ha e-ba le "boemo ba letsatsi la timetso" moo re felloang ke silevera, empa "maraka a tla fetoha ka theko e phahameng," oa lumela.
