Ngokokuqala ngqá, ithimba lamazwe ngamazwe lososayensi liye labonisa ukuthi kungenzeka ukukhiqiza amanani kagesi alinganisekayo lisebenzisa i-optical diode ngokuqondile emakhazeni angaphandle. Idivayisi ye-infrared semiconductor ebheke esibhakabhakeni isebenzisa umehluko wezinga lokushisa phakathi koMhlaba nesikhala ukuze ikhiqize amandla.
“Umkhathi omkhulu ngokwawo uwumthombo we-thermodynamic,” kuchaza uShanhui Fan, omunye wababhali bocwaningo. "Ngokombono we-optoelectronic physics, kukhona ukufana okuhle kakhulu phakathi kweqoqo lemisebe engenayo nephumayo."
Ngokungafani nokusebenzisa amandla afika eMhlabeni, njengoba kwenza amaphaneli elanga endabuko, i-optical diode engeyinhle ivumela ugesi ukuthi wenziwe njengoba ukushisa kuphuma phezulu futhi kugeleza kubuyela emkhathini. Ngokukhomba idivayisi yabo emkhathini ongaphandle, izinga lokushisa elisondela ku-zero ngokuphelele, iqembu lososayensi lakwazi ukuthola umehluko wokushisa omkhulu ngokwanele ukuze likhiqize amandla.
"Inani lamandla esikwazile ukulithola kulokhu kuhlolwa okwamanje lingaphansi kakhulu komkhawulo wethiyori," kunezela uMasashi Ono, omunye umbhali walolu cwaningo.
Ososayensi balinganisela ukuthi esimweni esikuso manje, umshini wabo ungakhiqiza ama-nanowatt angaba ngu-64 ngemitha-skwele ngayinye. Leli inani elincane kakhulu lamandla, kodwa kulokhu ubufakazi bomqondo ngokwawo bubalulekile. Ababhali bocwaningo bazokwazi ukuqhubeka nokwandisa idivayisi ngokuthuthukisa izakhiwo ze-quantum optoelectronic zezinto abazisebenzisayo ku-diode.
Izibalo zibonise ukuthi, uma kucatshangelwa imiphumela yomkhathi, ngokwethiyori, ngokuthuthuka okuthile, idivayisi edalwe ososayensi ingakhiqiza cishe u-4 W ngemitha yesikwele, cishe izikhathi eziyisigidi ngaphezu kwalokho okutholwe ngesikhathi sokuhlolwa, futhi ngokwanele ukufaka amandla amadivaysi amancane. .abadinga ukusebenza ebusuku. Uma kuqhathaniswa, ama-solar panel esimanje akhiqiza ama-watts aphakathi kuka-100 no-200 ngemitha-skwele ngayinye.
Nakuba imiphumela ibonisa isithembiso samadivayisi aqondiswe esibhakabhakeni, u-Shanhu Fan uphawula ukuthi isimiso esifanayo singasetshenziswa ukuze kusetshenziswe kabusha ukushisa okukhishwa emishinini. Okwamanje, yena nethimba lakhe bagxile ekuthuthukiseni ukusebenza kahle kwedivayisi yabo.
Ucwaningo ekushicilelweni kwesayensi kwe-American Institute of Physics (AIP).
