Amaseli Elanga eChalcogenide – Ukuthuthukiswa kanye namathemba esizukulwane esisha sobuchwepheshe be-Photovoltaic

Phakathi nokuthuthuka okuqhubekayo kobuchwepheshe be-photovoltaic, amaseli elanga e-chalcogenide, njengommeleli wesizukulwane sesithathu sobuchwepheshe be-photovoltaic, abe yinto ebalulekile emkhakheni wocwaningo lwesayensi kanye nemboni ngenxa yezinzuzo zawo eziyingqayizivele kanye namandla amakhulu. Muva nje, iqembu locwaningo eliholwa nguSolwazi Yuan Mingjian eSikoleni Sekhemistri saseNankai University lenze intuthuko enkulu ocwaningweni lwamaseli elanga e-chalcogenide, okufake amandla amasha ekuthuthukisweni kwale nsimu.

Izinzuzo eziyingqayizivele zamaseli elanga e-chalcogenide
I-Chalcogenide iyiklasi yezinto ezinesakhiwo sekristalu esiyingqayizivele, esinezinhlobo eziningi zezicelo kumaseli amasha elanga nakwamanye amadivayisi e-semiconductor. Isizathu sokuthi amaseli elanga e-chalcogenide adonsele ukunaka okukhulu kungenxa yezinzuzo ezilandelayo ezibalulekile:

1. Ukuguquguquka nokuhambisana:Izinto ze-Chalcocite zinokuguquguquka okuhle, zingalungiswa zibe amabhethri aguquguqukayo, okunikeza ithuba lokusetshenziswa kwezinye izimo ezikhethekile zohlelo lokusebenza, njengamadivayisi agqokwayo, imikhiqizo kagesi eguquguqukayo kanye neminye imikhakha, okwandisa kakhulu ububanzi bokusetshenziswa kobuchwepheshe be-photovoltaic.
2. Amandla okulungiselela endaweni enkulu:Uma kuqhathaniswa namaseli elanga endabuko asekelwe ku-silicon, amaseli elanga e-chalcogenide anezinzuzo ezisobala ekulungiseleleni indawo enkulu, ngokucubungula izixazululo kanye nezinye izindlela zokulungiselela ezingabizi kakhulu, ukuze kufezwe ukukhiqizwa kwebhethri endaweni enkulu, okubalulekile ekunciphiseni izindleko zemboni ye-photovoltaic, nokukhuthaza ukusetshenziswa okukhulu kobuchwepheshe be-photovoltaic.
3. Ukusebenza kahle kokuguqulwa kwethiyori okuphezulu:Ngokwemfundiso, amaseli elanga e-chalcogenide anokusebenza kahle kokuguqulwa kwe-photovoltaic okuphezulu, futhi ukusebenza kahle kwawo okulinganiselwe ngokwemfundiso kufana nokwamaseli elanga endabuko asekelwe ku-silicon. Ngokuqhubeka kokujula kocwaningo, ukusebenza kahle kokuguqulwa kwamaseli elanga e-chalcogenide nakho kuyathuthuka, okubonisa amandla amakhulu okuthuthuka.

Inselele yamaseli elanga e-chalcogenide
Naphezu kwezinzuzo eziningi zamaseli elanga e-chalcogenide, kodwa ngaphambi kokusetshenziswa kwayo okukhulu kwezentengiselwano, isabhekene nezinkinga ezibalulekile eziningi okudingeka zixazululwe, lapho inkinga yokuzinza ivelele khona kakhulu:

1. Ukuzinza okungekuhle kokushisa okuphezulu:Njengengqimba ebamba ukukhanya kwebhethri, ukuzinza kwezinto ze-chalcogenide kuthinteka kakhulu yizici zangaphandle zemvelo. Ekulungiseleleni amaseli elanga e-chalcogenide asebenza kahle kakhulu, kuvame ukudingeka ukuthembela ezithasiselweni zikasawoti we-amine eziphilayo eziguquguqukayo ukuze kuqiniswe isigaba somzimba futhi kulawulwe ukwakheka kwekristalu. Kodwa-ke, lesi sithako kulula kakhulu ukusibolisa emazingeni okushisa aphezulu, okubangela ukungalingani ekwakhiweni kwamakhemikhali kwefilimu ye-calcite, okunciphisa kakhulu ukuzinza kwebhethri ekusebenzeni kwezinga lokushisa eliphezulu, okuye kwaba ngenye yezithiyo eziyinhloko ezikhawulela ukusetshenziswa kwayo okukhulu kwezentengiselwano.
2. Ukungazinzi kwesikhathi eside okunganele:Ngaphezu kokuqina kokushisa okuphezulu, amaseli elanga e-chalcogenide asetshenziswa isikhathi eside enkambisweni, kodwa futhi abhekene nokuguga kwezinto ezibonakalayo, ukuncishiswa kokukhanya nezinye izinto eziholela ekuwohlokeni kokusebenza, okuthinta futhi ukusebenziseka kanye nokuthembeka kwezicelo zayo zezentengiselwano ngezinga elithile.

Impumelelo yakamuva yocwaningo kanye nempumelelo
Ehlose inkinga yokungazinzi kahle kokusebenza kwamaseli elanga e-chalcogenide ngaphansi kwezimo zokusebenza ezishisa kakhulu, uSolwazi Yuan Mingjian weSikole Sekhemistri, eNyuvesi yaseNankai, wahola iqembu locwaningo ukuthi lenze ucwaningo lokubambisana lwamazwe ngamazwe olusezingeni eliphezulu, futhi wathola imiphumela emangalisayo:

1. Ukuthuthukiswa kwesu elisha lokulungiselela:Ithimba locwaningo lihlanganise nezibikezelo zemfundiso futhi lathuthukisa ngempumelelo isu lokulungiselela i-alloy chalcogenide enokuqina okuphezulu kokushisa. Leli su lixazulula ngokuphelele inkinga yokungalingani kwengxenye ye-cesium methamidic yamafilimu e-chalcogenide, futhi ngokuyisisekelo lithuthukisa ukuzinza kwezinto ze-chalcogenide.
2. Inhlanganisela yokusebenza kahle okuphezulu kanye nokuqina okuphezulu:Amadivayisi e-Chalcogenide solar cell alungiselelwe yileli cebo abonise ukusebenza kahle kokuguqulwa kwamandla okusezingeni eliphezulu kanye nokuqina kokushisa okuphezulu. Le mpumelelo ayibeki nje kuphela isisekelo esiqinile sobuchwepheshe sokuthuthukiswa kokuqina kwamaseli e-chalcogenide solar, kodwa futhi ivula ithuba elibanzi lokwenziwa ngcono nokusebenza kahle kobuchwepheshe be-photovoltaic.
3. Ukushicilelwa kanye nokubaluleka kwemiphumela:Ngobusuku bangoSepthemba 30, i-Nature yashicilela imiphumela yocwaningo ngaphansi kwesihloko esithi “Ingxenye ye-Cesium amidine yamaseli elanga e-chalcogenide enokuqina okuphezulu kokushisa”. Lolu cwaningo lubaluleke kakhulu ekukhuthazeni ukuguqulwa okuluhlaza kwesakhiwo samandla omhlaba wonke futhi luphawula intuthuko enkulu esizukulwaneni esisha sobuchwepheshe be-photovoltaic.

Amathemba entuthuko yesikhathi esizayo
Ngokufezwa kwalo mphumela wocwaningo, ithemba lokuthuthukiswa kweseli yelanga ye-calcite liye lakhanya kakhulu. Njengamanje, ithimba locwaningo likhuthaza ngenkuthalo ucwaningo nokuthuthukiswa kwamamojula eseli yelanga ye-chalcogenide esebenza kahle ngokuhambisana nezidingo zokuthuthukiswa kwezimboni ngokubambisana phakathi kwezikole namabhizinisi, ngomzamo wokukhuthaza ukusetshenziswa okungokoqobo kwemiphumela yocwaningo ngokushesha okukhulu kanye nokuthuthukiswa kwezimboni zokufika.

1. Ukuthuthukiswa kwezimboni okusheshayo:Lokhu kuthuthuka kuzosheshisa kakhulu ukuthuthukiswa kwamaseli elanga e-chalcogenide, okulindeleke ukuthi afinyelele ekukhiqizweni nasekusetshenzisweni okukhulu kwezentengiselwano eminyakeni embalwa ezayo, futhi ahlinzeke ngezixazululo zamandla ahlanzekile ezisebenza kahle futhi ezingabizi kakhulu emakethe yamandla yomhlaba wonke.
2. Ukwandiswa kohlelo lokusebenza:Ngokuthuthuka okuqhubekayo kokusebenza kwamaseli elanga kanye nokwehliswa okuqhubekayo kwezindleko zamaseli elanga e-chalcogenide, izindawo zokusetshenziswa kwawo zizokwandiswa kakhulu. Ngaphezu kwezitshalo zamandla ze-photovoltaic zendabuko, ukukhiqizwa kwamandla okusatshalaliswa kanye neminye imikhakha, kodwa futhi nasekuhlanganisweni kwezakhiwo, amandla eselula, i-Intanethi Yezinto kanye nezinye izindawo ezisafufusa zidlala indima ebalulekile.
3. Khuthaza ushintsho lwesakhiwo samandla:Njengobuchwepheshe bamandla ahlanzekile, avuselelekayo, ukusetshenziswa kabanzi kwamaseli elanga e-calcite kuzosiza ekukhuthazeni ukuguqulwa okuluhlaza kwesakhiwo samandla omhlaba wonke, kunciphise ukuncika emandleni endabuko ezinto ezingaphili, kunciphise ukukhishwa kwekhabhoni, futhi kube negalelo elihle ekulweni nokushintsha kwesimo sezulu emhlabeni jikelele.
