Teadlaste t\u00f6\u00f6 on varases staadiumis \u2013 siiani on uurijatel \u00f5nnestunud parandada toodetavate p\u00e4ikesepatareide t\u00f5husust vaid poole protsendi v\u00f5rra. Laborikatsete p\u00f5hjal arvavad nad aga, et t\u00f5husust on v\u00f5imalik t\u00f5sta nelja protsendi v\u00f5rra \u2013 umbes 16-lt protsendilt 20-ni. See oleks suur edasiminek p\u00e4ikeseenergiat\u00f6\u00f6stuses, milles on oluline isegi pooleprotsendiline t\u00f5us t\u00f5hususes. Loodetavasti on seda optilist ahju v\u00f5imalik rakendada t\u00f6\u00f6stuses v\u00f5imalikult kiiresti, et l\u00f5igata kasu soodsamalt valmistatavatest p\u00e4ikesepaneelidest.<\/p>\n

Ere tulevik p\u00e4ikesepaneelide jaoks<\/strong><\/p>\n

K\u00f5ik solaartehnoloogia l\u00e4bimurded, edasiminekud ja viimistlused, mis muudavad p\u00e4ikeseenergia kogumiseks, salvestamiseks ja kasutamiseks vajaminevate seadmete tootmise, paigaldamise ja t\u00f6\u00f6tamise odavamaks, lisanduvad aja jooksul kasvavas tempos. Need viitavad tulevikule, kus p\u00e4ikeseenergia v\u00f5ib maksta v\u00e4hem kui 80 eurosenti vati kohta ning kus maailma p\u00e4ikeseenergiatootjate\u00a0v\u00f5imsus gigavattides aasta kohta pidevalt\u00a0t\u00f5useks.<\/p>\n

See pole aga imerohi k\u00f5ikide probleemide vastu\u00a0p\u00e4ikeseenegia vallas. Energiatalletus on j\u00e4tkuvalt suureks v\u00e4ljakutseks: p\u00e4ikeseenergia t\u00f6\u00f6tab k\u00f5ige paremini kombineerituna teiste \u201epuhaste\u201c allikatega. Edasiminek\u00a0toimub, kuid j\u00e4tkuvat progressi ei tohiks v\u00f5tta iseeneesestm\u00f5istetavana.<\/p>\n
