Imbali yezicelo ze-thermal zelanga zide kunezo zezicelo ze-photovoltaic, izifudumezi zamanzi zelanga zentengiso zavela kwi-1891 izicelo ze-thermal zelanga zihamba ngokufunxa ukukhanya kwelanga, amandla okukhanya kumandla okushisa emva kokusetyenziswa ngokuthe ngqo okanye ukugcinwa kungaguqulelwa kumbane ngokufudumeza iijeneretha eziqhutywa ngumphunga. Ukusetyenziswa kwe-solar thermal kunokwahlulwa ngokweendidi ezintathu ngokoluhlu lobushushu: izicelo eziphantsi kobushushu (<100C), ikakhulu ezisetyenziselwa ukufudumeza i-swimming pool, i-ventilation air preheating, njl., izicelo zobushushu obuphakathi (100 ~ 400C), ikakhulu ezisetyenziselwa amanzi ashushu asekhaya kunye nokufudumeza kwegumbi, inkqubo yokufudumeza kumashishini, njl. izicelo zobushushu obuphezulu (> 400C), ikakhulu esetyenziselwa ukufudumeza kwimizi-mveliso, ukuvelisa amandla thermal, njl. Ngokukhuthazwa inkqubo yokuvelisa amandla umqokeleli, ukuxhathisa ubushushu obuphakathi kunye nobushushu obuphakathi kunye nokusingqongileyo photothermal izinto zophando iye yaba yinto ephambili.
Itekhnoloji yefilimu encinci idlala indima ebalulekileyo kwizicelo zokushisa kwelanga. Ngenxa yoxinano lwamandla elanga asezantsi kumphezulu (malunga ne-1kW/m² emini emaqanda, abaqokeleli bafuna indawo enkulu yokuqokelela amandla elanga. Indawo enkulu/yobungqingqwa bomlinganiselo weefilimu zesolar photothermal ibangela iifilim ezisengozini yokuguga, nto leyo echaphazela ubomi bezixhobo zesolar photothermal. Iimfuno eziphambili ze-solar Spectrum esebenzayo: iifilimu ezisetyenziswayo ze-solar ezisetyenzisiweyo kunye noqoqosho olude olusetyenzisiweyo lusebenza ngokufanelekileyo, iifilimu ezisetyenziswayo ze-solar kunye noqoqosho olude. Ukuvavanya ukusebenza kakuhle kwamandla efilimu eshushu yelanga ifilimu eshushu yelanga kufuneka ifunxe ngokugqwesileyo kuluhlu olubanzi lweebhanti zemitha yelanga kunye nokukhutshwa kwe-thermal ephantsi isetyenziselwa ukuvavanya ukukhethwa kwefilimu, apho imele i-solar absorptivity kunye ne-emismal yokusebenza ngokungafaniyo. Iifilimu zakwangoko ezifunxa ubushushu zaziquka ukwambathisa okumnyama kwifoyile yentsimbi, ephulukene nemitha engamaza eepesenti ezingama-45 ekhutshwayo njengoko ifunxa ubushushu kwaye ifudumala, nto leyo ekhokelela ekuvunweni kwamandla elanga ngeepesenti ezingama-50 kuphela Ukuphumelela kweefilimu zefotothermal kunokuphuculwa kakhulu ngokusebenzisa imathiriyeli yespectrally-platinum, njengespectrally-platformic materialive, njengecarter-platinum. kunye ne-nitrides yezinye iinguqu zesinyithi. (<3um), kunye ne-coefficient ye-thermal radiation engaphantsi kwe-0.05 kwi-500C yebhanti ye-thermal radiation (> 3um), kunye nesakhiwo kunye nokusebenza-zinzile kwi-500 ° C emoyeni womoya.
