Kwa nthawi yoyamba, gulu lapadziko lonse la asayansi lasonyeza kuthekera kopanga magetsi ochuluka omwe angayesedwe pogwiritsa ntchito optical diode mwachindunji kuchokera kuzizira kwa kunja. Chipangizo choyang'ana kumwamba cha infrared semiconductor chimagwiritsa ntchito kusiyana kwa kutentha pakati pa Dziko Lapansi ndi mlengalenga kuti apange mphamvu.
"Chilengedwe chachikulu chomwe chili ndi mphamvu ya thermodynamic," akufotokoza motero Shanhui Fan, m'modzi mwa olemba maphunzirowo. "Kutengera mawonekedwe a optoelectronic physics, pali kufanana kokongola kwambiri pakati pa kusonkhanitsa kwa radiation yomwe ikubwera ndi yotuluka."
Mosiyana ndi kugwiritsa ntchito mphamvu zomwe zimabwera kudziko lapansi, monga momwe ma solar achikhalidwe amachitira, mawonekedwe owoneka bwino amalola magetsi kupangidwa pamene kutentha kumachoka pamwamba ndikubwereranso mumlengalenga. Poloza chipangizo chawo mumlengalenga, kutentha kwake kukuyandikira ziro, gulu la asayansi linatha kupeza kusiyana kwa kutentha kwakukulu kuti apange mphamvu.
"Kuchuluka kwa mphamvu zomwe tinatha kupeza kuchokera ku kuyesera kumeneku panopa kuli pansi pa malire," akuwonjezera Masashi Ono, wolemba wina wa phunziroli.
Asayansi amayerekezera kuti m’njira imene ali nayo panopa, chipangizo chawo chikhoza kupanga ma nanowati 64 pa lalikulu mita imodzi. Izi ndizochepa kwambiri mphamvu, koma pamenepa umboni wa lingaliro lokha ndilofunika. Olemba a phunziroli adzatha kupititsa patsogolo chipangizochi mwa kukonza quantum optoelectronic properties za zipangizo zomwe amagwiritsa ntchito mu diode.
Kuwerengera kunasonyeza kuti, poganizira zotsatira za mumlengalenga, mwachidziwitso, ndi kusintha kwina, chipangizo chopangidwa ndi asayansi chikhoza kupanga pafupifupi 4 W pa mita lalikulu, pafupifupi nthawi miliyoni kuposa zomwe zinapezedwa panthawi yoyesera, komanso zokwanira kuti zigwiritse ntchito zipangizo zazing'ono. amene ayenera kugwira ntchito usiku. Poyerekeza, mapanelo amakono a solar amatulutsa pakati pa 100 ndi 200 watts pa lalikulu mita.
Ngakhale zotsatira zikuwonetsa kulonjeza kwa zida zomwe zimayang'ana kumwamba, Shanhu Fan akuti mfundo yomweyi ingagwiritsidwe ntchito pokonzanso kutentha komwe kumachokera kumakina. Pakalipano, iye ndi gulu lake akuyang'ana kwambiri pakukonzekera bwino kwa chipangizo chawo.
