Asayansi akupitiriza kukankhamapanelo a dzuwakuti ikhale yogwira mtima kwambiri, ndipo pali mbiri yatsopano yoti inene: Selo latsopano ladzuwa limakwanitsa kuchita bwino ndi 39.5 peresenti pansi pa mikhalidwe yowunikira padziko lonse lapansi ya dzuwa limodzi.
Chizindikiro cha 1-dzuwa ndi njira yokhazikika yoyezera kuchuluka kwa dzuwa, tsopano pafupifupi 40% ya ma radiation amatha kusinthidwa kukhala magetsi.solar panelzinthu zinali 39.2%.
Pali mitundu yambiri ya ma cell a solar mozungulira kuposa momwe mungaganizire.Mtundu womwe umagwiritsidwa ntchito pano ndi ma cell a solar amtundu wachitatu-Junction III-V, omwe amagwiritsidwa ntchito kwambiri m'masetilaiti ndi ndege, ngakhale ali ndi kuthekera kwakukulu pamtunda wolimba.
"Maselo atsopanowa ndi othandiza komanso osavuta kupanga, ndipo akhoza kukhala othandiza pazinthu zosiyanasiyana zatsopano, monga ntchito zolephereka kwambiri kapena malo ochepetsera mpweya," anatero katswiri wa sayansi ya sayansi Myles Steiner wa National Renewable Energy Laboratory..”NREL) ku Colorado.
Ponena za mphamvu ya maselo a dzuwa, gawo la "junction katatu" la equation ndilofunika.Mfundo iliyonse imayikidwa mu gawo linalake la mawonekedwe a dzuwa, zomwe zikutanthauza kuti kuwala kochepa kumatayika komanso kusagwiritsidwa ntchito.
Kuchita bwino kumapitilizidwa bwino pogwiritsa ntchito luso lotchedwa "quantum well" teknoloji. Fizikiki yomwe ili kumbuyo kwawo ndi yovuta kwambiri, koma lingaliro lalikulu ndiloti zipangizozo zimasankhidwa mosamala ndi kukonzedwa bwino, komanso zowonda kwambiri. Izi zimakhudza kusiyana kwa gulu, mphamvu zochepa zomwe zimafunikira kusangalatsa ma elekitironi ndikulola kuti magetsi aziyenda.
Pachifukwa ichi, magawo atatuwa amakhala ndi gallium indium phosphide (GaInP), gallium arsenide (GaAs) yokhala ndi mphamvu yowonjezera yochulukirapo, ndi gallium indium arsenide (GaInAs).
"Chofunika kwambiri ndi chakuti ngakhale GaAs ndi zinthu zabwino kwambiri ndipo amagwiritsidwa ntchito kwambiri mu III-V ma cell ophatikizika, alibe bandgap yeniyeni ya ma cell ophatikizika atatu, zomwe zikutanthauza kuti chithunzithunzi pakati pa ma cell atatu Kuwerengera sikuli koyenera, "Anatero Ryan France, katswiri wa sayansi ya sayansi ya NREL.
"Apa, tasintha kusiyana kwa bandi pogwiritsa ntchito zitsime za quantum, ndikusunga zinthu zabwino kwambiri, zomwe zimathandizira chipangizochi komanso ntchito zina."
Zina mwazowonjezera zomwe zawonjezeredwa mu selo laposachedwa ndi kuonjezera kuchuluka kwa kuwala komwe kumatengedwa popanda kutayika kwa magetsi.
Uku ndiye kuwongolera kwambiri kwadzuwa 1 kuposa chilichonsesolar panelselo pa mbiri, ngakhale kuti tawona zogwira mtima kwambiri kuchokera ku dzuwa lamphamvu kwambiri.Ngakhale kuti zidzatenga nthawi kuti teknoloji ichoke ku labu kupita ku mankhwala enieni, zosintha zomwe zingatheke ndizosangalatsa.
Maselowo adalembanso zochititsa chidwi za 34.2 peresenti ya danga, zomwe ziyenera kukwaniritsa zikagwiritsidwa ntchito pozungulira.
"Monga awa ndi maselo a dzuwa a 1 omwe amagwira ntchito bwino kwambiri panthawi yolemba, maselowa amakhazikitsanso ndondomeko yatsopano yokwaniritsira luso lamakono la photovoltaic," ofufuzawo analemba mu pepala lawo lofalitsidwa.
