Cercet\u0103tori saudi au efectuat o serie de experimente cu panouri solare sub form\u0103 de sfere mici. Forma rotund\u0103 a fotoconvertorului permite o captare mai bun\u0103 a luminii solare reflectate \u0219i dispersate. De\u0219i pentru fermele solare industriale aceasta nu este o solu\u021bie viabil\u0103, pentru o serie de aplica\u021bii, panourile solare rotunde pot reprezenta o adev\u0103rat\u0103 descoperire.<\/p>\n

\"Elementele<\/p>\n

Un grup de cercet\u0103tori de la Universitatea de \u0218tiin\u021b\u0103 \u0219i Tehnologie King Abdullah a extins domeniul dezvolt\u0103rilor sale privind panourile solare cu diferite grade de curbur\u0103 a suprafe\u021bei printr-o nou\u0103 cercetare. \u00cen special, ei au creat<\/a><\/noindex> un element solar \u00een form\u0103 de sfer\u0103, de dimensiunea unei mingi de tenis, \u0219i s-au realizat numeroase experimente cu acesta. Aceasta a permis dezvoltarea tehnologiei de \u201ecre\u021bare\u201d a panourilor solare plano, care const\u0103 \u00een crearea de caneluri \u00een substratul de siliciu cu un laser, care servesc ca locuri sigure pentru \u00eendoirea panourilor.<\/p>\n

Compararea func\u021bion\u0103rii unui element plat \u0219i a unuia sferic de aceea\u0219i suprafa\u021b\u0103 \u00een condi\u021bii de \u00eenc\u0103pere cu o surs\u0103 artificial\u0103 de radia\u021bie solar\u0103 a ar\u0103tat c\u0103, la iluminare direct\u0103, elementul solar sferic asigur\u0103 o putere de ie\u0219ire cu 24 % mai mare comparativ cu elementul solar plat tradi\u021bional. Dup\u0103 \u00eenc\u0103lzirea elementelor de c\u0103tre \u201erazele solare\u201d, avantajul elementului rotund cre\u0219te la 39 %. Aceasta se datoreaz\u0103 faptului c\u0103 \u00eenc\u0103lzirea reduce eficien\u021ba panourilor, iar forma sferic\u0103 elibereaz\u0103 mai bine c\u0103ldura \u00een spa\u021biu \u0219i sufer\u0103 mai pu\u021bin de pe urma c\u0103ldurii (\u00ee\u0219i men\u021bine mai mult timp o eficien\u021b\u0103 ridicat\u0103).<\/p>\n

<\/center><\/p>\n

Dac\u0103 elementele solare rotunde \u0219i plate colectau exclusiv lumina dispersat\u0103, atunci puterea de ie\u0219ire a elementului rotund era cu 60 % mai mare dec\u00e2t cea a celui plat. Mai mult, un fundal reflectant ales corespunz\u0103tor, iar oamenii de \u0219tiin\u021b\u0103 au experimentat cu diverse materiale naturale \u0219i artificiale, permitea elementului solar sferic s\u0103 dep\u0103\u0219easc\u0103 elementul plat cu 100 % \u00een ceea ce prive\u0219te nivelul energiei generate.<\/p>\n

Potrivit cercet\u0103torilor, elementele solare sferice ar putea stimula dezvoltarea Internetului lucrurilor \u0219i a altor electronice autonome. \u00cempreun\u0103, acestea promit a fi mai ieftine dec\u00e2t utilizarea elementelor solare plate. Panourile solare circulare nu necesit\u0103 sisteme de urm\u0103rire a soarelui. De asemenea, ele s-ar putea dovedi mai eficiente \u00een utilizarea \u00een interior.<\/p>\n

\u00cen etapa urm\u0103toare a cercet\u0103rilor, oamenii de \u0219tiin\u021b\u0103 inten\u021bioneaz\u0103 s\u0103 verifice eficien\u021ba panourilor solare circulare \u00een diferite col\u021buri ale lumii, \u00een diferite condi\u021bii de iluminare. De asemenea, sper\u0103 s\u0103 creeze elemente solare sferice de mari dimensiuni: \u00eentre 9 \u0219i 90 m2. \u00cen final, cercet\u0103torii inten\u021bioneaz\u0103 s\u0103 investigheze alte forme ale suprafe\u021belor curbe ale elementelor solare, av\u00e2nd speran\u021ba de a g\u0103si o solu\u021bie ideal\u0103 pentru anumite domenii de aplicare.<\/p>\n
