Umlando wokusetshenziswa kokushisa kwelanga mude kunokusetshenziswa kwe-photovoltaic, ama-heater amanzi elanga ebhizinisi avele ngo-1891 ukusetshenziswa kokushisa kwelanga ngokusebenzisa ukumuncwa kwelanga, amandla okukhanya abe amandla okushisa ngemva kokusetshenziswa noma ukugcinwa ngqo kungaguqulwa kube ugesi ngokushisa ama-generator aqhutshwa umusi. Ukusetshenziswa kokushisa kwelanga kungahlukaniswa ngezigaba ezintathu ngokuya ngobubanzi bokushisa: ukusetshenziswa kokushisa okuphansi (<100C), okusetshenziselwa kakhulu ukufudumeza ichibi lokubhukuda, ukufudumala komoya wokungenisa umoya, njll., ukusetshenziswa kokushisa okuphakathi (100 ~ 400C), okusetshenziselwa kakhulu amanzi ashisayo asekhaya kanye nokushisa kwegumbi, ukufudumala kwenqubo embonini, njll.; ukusetshenziswa kokushisa okuphezulu (>400C), okusetshenziselwa kakhulu ukufudumeza kwezimboni, ukukhiqizwa kwamandla okushisa, njll. Ngokukhuthazwa kohlelo lokukhiqizwa kwamandla okuqoqa, ukumelana nokushisa okuphakathi kanye nokushisa okuphezulu kanye nocwaningo lwezinto ezivikela imvelo ezimelana ne-photothermal sekube yinto eza kuqala.
Ubuchwepheshe befilimu encane budlala indima ebalulekile ekusetshenzisweni kokushisa kwelanga. Ngenxa yobuningi bamandla elanga obuphansi ebusweni (cishe i-1kW/m² emini, abaqoqi badinga indawo enkulu ukuze baqoqe amandla elanga. Isilinganiso esikhulu sendawo/ukujiya kwamafilimu e-solar photothermal siphumela kumafilimu asengozini yokuguga, okuthinta impilo yemishini ye-solar photothermal. Izidingo ezibalulekile zamafilimu e-solar thermal ziphindwe kathathu: ukusebenza kahle kwamandla okuphezulu, impilo ende kanye nokonga. Ukukhetha kwe-Spectral kusetshenziswa ukuhlola ukusebenza kahle kwamandla kwamafilimu e-solar thermal. Ifilimu enhle ye-solar thermal idinga ukuba nokumuncwa okuhle kakhulu phezu kwezinhlobo eziningi zemisebe yelanga kanye nokukhishwa okuphansi kokushisa. I-a/e coefficient isetshenziselwa ukuhlola ukukhetha kwe-spectral kwefilimu, lapho u-a emele ukumuncwa kwelanga kanye no-e emele ukumuncwa kokushisa. Ukusebenza kokushisa kwamafilimu ahlukene kuyahlukahluka kakhulu. Amafilimu okuqala okumunca ukushisa ayenengubo emnyama ku-foil yensimbi, elahlekelwe amaphesenti angama-45 emisebe ye-long-wavelength ekhishwa njengoba imunca ukushisa futhi ifudumala, okuholela ekuvunweni kwamandla elanga ngamaphesenti angama-50 kuphela. Ukusebenza kahle kwamafilimu e-photothermal kungathuthukiswa kakhulu ngokusebenzisa ifilimu encane ekhethiwe ye-spectrally. izinto ezifana nensimbi yeplatinum, i-chromium, noma ama-carbide kanye nama-nitride ezinye zezinsimbi ezishintshayo. Amafilimu e-photothermal avame ukulungiswa yi-CVD noma i-magnetron sputtering, futhi ukukhishwa kwe-thermal kungancishiswa kube ngamaphesenti ayi-15 kumafilimu anokusebenza kahle kokuqoqa okungafika kumaphesenti angama-80. Amafilimu aqoqiwe akhethiwe kahle ane-spectrally selective coefficient yokumunca engaphezu kuka-0.98 kuma-band amakhulu e-solar spectrum (<3um), kanye ne-thermal radiation coefficient engaphansi kuka-0.05 ku-500C thermal radiation band (>3um), futhi azinzile ngokwesakhiwo nokusebenza ku-500°C emoyeni.
