Saudijski znanstvenici proveli su niz eksperimenata s solarnim elementima u obliku male sfere. Okrugli oblik fotopreuzimatelja omogu\u0107uje bolje hvatanje reflektirane i raspr\u0161ene sun\u010deve svjetlosti. Za industrijske solarne farme to vjerojatno nije razborito rje\u0161enje, no za niz primjena okrugli solarni elementi mogli bi se pokazati pravim otkri\u0107em.<\/p>\n

\"Sferni<\/p>\n

Grupa znanstvenika sa Sveu\u010dili\u0161ta kralja Abdullaha za znanost i tehnologiju (King Abdullah University of Science and Technology) pro\u0161irila je podru\u010dje svojih istra\u017eivanja za razvoj solarnih panela s razli\u010ditim stupnjevima zakrivljenosti povr\u0161ine novim istra\u017eivanjem. Konkretno, oni sustavljali su<\/a><\/noindex> sferni solarni element veli\u010dine teniskog lopte, s kojim su provedeni mnogi eksperimenti. To je omogu\u0107ilo tehnologiju \u201evaljanja\u201d ravnih solarnih panela, koja se sastoji od stvaranja izreza laserom u silicijskoj podlozi, koji slu\u017ee kao sigurno mjesto za savijanje panela.<\/p>\n

Usporedba rada ravnog i sfernog elementa iste povr\u0161ine u uvjetima prostora s umjetnim izvorom sun\u010devog zra\u010denja pokazala je da sferni solarni element pri izravnom osvjetljenju osigurava 24 % ve\u0107u izlaznu snagu u usporedbi s tradicionalnim ravnim solarnih elementom. Nakon zagrijavanja elemenata \u201esun\u010devim zrakama\u201d porast prednosti okruglog elementa pove\u0107ava se na 39 %. To je povezano s tim da zagrijavanje smanjuje u\u010dinkovitost panela, a sferni oblik bolje ispu\u0161ta toplinu u prostor i manje pati od zagrijavanja (du\u017ee zadr\u017eava visoku u\u010dinkovitost).<\/p>\n

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

Ako su okrugni i ravni solarni elementi prikupljali isklju\u010divo raspr\u0161enu svjetlost, izlaz snage s okrugnog elementa bio je 60 % ve\u0107i nego onaj od ravnog. \u0160tovi\u0161e, ispravno odabrana reflektiraju\u0107a pozadina, s kojom su znanstvenici eksperimentirali s raznim prirodnim i umjetnim reflektorima, omogu\u0107ila je sfernom solarno elementu da u pogledu proizvodnje energije nadma\u0161i ravni za 100 %.<\/p>\n

Prema mi\u0161ljenju istra\u017eiva\u010da, sferni solarni elementi mogu potaknuti razvoj Interneta stvari i druge autonomne elektronike. Zajedno obe\u0107avaju da \u0107e biti jeftiniji od kori\u0161tenja ravnih solarnih elemenata. Okruglim solarnim panelima nisu potrebni sustavi pra\u0107enja sunca. Tako\u0111er, mogu biti bolji za kori\u0161tenje u zatvorenim prostorima.<\/p>\n

U sljede\u0107oj fazi istra\u017eivanja, znanstvenici planiraju ispitati u\u010dinkovitost okruglih solarnih panela na raznim mjestima na Zemlji u \u0161irokom rasponu mogu\u0107eg osvjetljenja. Tako\u0111er se nadaju stvoriti sferne solarne elemente velike povr\u0161ine: od 9 do 90 m\u00b2. Na kraju, znanstvenici \u0107e istra\u017eiti druge oblike zakrivljene povr\u0161ine solarnih elemenata, u nadi da \u0107e prona\u0107i idealno rje\u0161enje za odre\u0111ena podru\u010dja primjene.<\/p>\n
