Umngeni weeseli zelanga ze-chalcogenide
Nangona iingenelo ezininzi zeeseli zelanga ze-chalcogenide, kodwa ngaphambi kokuba zisetyenziswe kakhulu kwezorhwebo, zisajongene nemiba emininzi ebalulekileyo ekufuneka isonjululwe, apho ingxaki yokuzinza iphambili khona:

1. Uzinzo olubi kubushushu obuphezulu:Njengomaleko webhetri ofunxa ukukhanya, ukuzinza kwezinto ze-chalcogenide kuchaphazeleka kakhulu zizinto zangaphandle ezingqongileyo. Xa kulungiswa iiseli zelanga ze-chalcogenide ezisebenza kakuhle, kudla ngokuba yimfuneko ukuxhomekeka kwizithako zetyuwa ye-amine eziguquguqukayo ukuze kuzinziswe isigaba somzimba kunye nokulawula i-crystallization. Nangona kunjalo, esi sithako kulula kakhulu ukusibolisa kumaqondo obushushu aphezulu, okubangela ukungalingani kwimilo yeekhemikhali yefilimu ye-calcite, nto leyo enciphisa kakhulu ukuzinza kwebhetri ekusebenzeni kwamaqondo obushushu aphezulu, eye yaba yenye yezona zinto ziphambili ezithintela ukusetyenziswa kwayo okukhulu kwezorhwebo.
2. Ukungonelanga kozinzo lwexesha elide:Ukongeza uzinzo lobushushu obuphezulu, iiseli zelanga ze-chalcogenide zisetyenziswa ixesha elide kwinkqubo, kodwa zijongene nokuguga kwezinto, ukuncitshiswa kokukhanya kunye nezinye izinto ezikhokelela ekuwohlokeni kokusebenza, nto leyo echaphazela ukwenzeka kunye nokuthembeka kwezicelo zayo zorhwebo ukuya kwinqanaba elithile.

Impumelelo yophando lwamva nje kunye nempumelelo
Ejolise kwingxaki yokungazinzi kakuhle kokusebenza kweeseli zelanga ze-chalcogenide phantsi kweemeko zokusebenza ezishushu kakhulu, uNjingalwazi uYuan Mingjian weSikolo seKhemistri, kwiYunivesithi yaseNankai, wakhokela iqela lophando ukuba lenze uphando oluphezulu lwentsebenziswano yamazwe ngamazwe, waza wafumana iziphumo ezimangalisayo:

1. Uphuhliso lwesicwangciso esitsha sokulungiselela:Iqela lophando lidibene nezibikezelo zethiyori kwaye laphumelela ekuphuhliseni icebo lokulungiselela i-alloy chalcogenide enozinzo oluphezulu lobushushu. Eli cebo lisombulula ngokupheleleyo ingxaki yokungahambelani kwecandelo le-cesium methamidic leefilimu ze-chalcogenide, kwaye ngokusisiseko liphucula uzinzo lwezinto ze-chalcogenide.
2. Ukudibanisa ukusebenza kakuhle kunye nozinzo oluphezulu:Izixhobo zeeseli zelanga zeChalcogenide ezilungiselelwe ngolu cwangciso zibonakalise ukusebenza kakuhle kokuguqulwa kwamandla omgangatho wehlabathi kunye nokuzinza kobushushu obuphezulu. Le mpumelelo ayibeki nje kuphela isiseko sobugcisa esiqinileyo sokuphucula uzinzo lweeseli zelanga zechalcogenide, kodwa ikwavula nethuba elibanzi lokwenza ubuchwepheshe be-photovoltaic busebenze ngakumbi kwaye buthengiswe.
3. Ukupapashwa kunye nokubaluleka kweziphumo:Ngobusuku bangoSeptemba 30, iNature yapapasha iziphumo zophando phantsi kwesihloko esithi “Icandelo le-Cesium amidine leeseli zelanga ze-chalcogenide ezinozinzo oluphezulu lobushushu”. Olu phando lubaluleke kakhulu ekukhuthazeni utshintsho oluluhlaza kwisakhiwo samandla ehlabathi kwaye luphawula inkqubela phambili enkulu kwisizukulwana esitsha setekhnoloji ye-photovoltaic.

Amathuba ophuhliso lwexesha elizayo
Ngokufezekiswa kwesi siphumo sophando, ithemba lokuphuhliswa kweseli yelanga ye-calcite liye laqaqamba ngakumbi.
