3. Ixesha elide lokuphila kunye nozinzo
Iiseli zelanga ze-CdTe ezibhityileyo nazo zibalaseleyo ngokuqina kwazo okumangalisayo kunye nokuzinza kwiindawo zangaphandle. Ngokweemvavanyo ezivela kwiNational Renewable Energy Laboratory (NREL), iimodyuli ze-CdTe zigcine i-88% yokusebenza kwazo kokuqala emva kweminyaka engama-27 yokusebenza (1995-2021), kunye nokuwohloka kwe-12% kuphela. Ngokwahlukileyo koko, iimodyuli ze-silicon zekristale eziqhelekileyo zifumana ukulahleka kokusebenza okumalunga nama-20% kwixesha elifanayo. Olu bude bexesha elide olumangalisayo lwenza iiseli ze-CdTe zibe ngumthombo othembekileyo wamandla azinzileyo kwizakhiwo eziluhlaza kunye ne-BIPV.
4. Ukuhambelana okuqinileyo noyilo lwezakhiwo
Enye yezona zinto zibalulekileyo zeglasi yelanga yeCdTe kukuyilwa kwayo okunokwenziwa ngokwezifiso, okuhambelana nobuchule babakhi bezakhiwo kunye nezinto abazikhethayo ngabanye abanini bezakhiwo. Nokuba kungokwemibala, ubunjani, okanye ubungakanani, iglasi yeCdTe inokulungiswa ukuze idityaniswe kakuhle nobuhle besakhiwo. Oku kuguquguquka kuvumela iglasi yelanga yeCdTe ukuba ingasebenzi nje kuphela njengomthombo wamandla kodwa ikwayinto yoyilo, iphucula ukusebenza kunye nomtsalane wesakhiwo.
5. Ukuhanjiswa kokukhanya okugqwesileyo
Iimodyuli zelanga zeCdTe zidibanisa i-cadmium telluride neglasi eqhubayo, zibonelela ngokuhanjiswa kokukhanya okusebenzayo ngelixa zihlangabezana neemfuno zesakhiwo zokukhanya kwasemini. Ezi modyuli zifumaneka ngemibala eyahlukeneyo, ziqinisekisa ukusasazwa kokukhanya okufanayo, ziphucula ukuvisisana kwazo okubonakalayo nokusebenzayo noyilo lwesakhiwo.
6. Ukhuseleko oluPhezulu
Iimodyuli zelanga zemveli, xa zifakwe umthunzi kancinci ngokuhamba kwexesha, zinokuchaphazeleka ziziphumo zeendawo ezishushu, apho ubushushu obugqithisileyo bendawo obubangelwa ngumbane ophezulu bunokunciphisa ukusebenza kwaye bunciphise ubomi benkqubo. Kwiimeko ezigqithisileyo, oku kunokukhokelela kwiingozi zomlilo. Iimodyuli zeCdTe, ezinombane ophantsi kunye nokwanda kobushushu okunciphileyo, zibonisa iziphumo ezincinci zeendawo ezishushu, ziqinisekisa ukhuseleko oluphezulu kunye nozinzo lwenkqubo.
7. Ukuxhomekeka okuncinci kokuthambekela
Iimodyuli zeCdTe zibalasele ekutsaleni ukukhanya okusasazekayo, nto leyo eyenza zingaxhomekeki kakhulu kwi-engile yokufakela. Nokuba phantsi kwee-engile ezigqithisileyo, iiphaneli zeCdTe zigcina ukuveliswa kwamandla okuphezulu xa kuthelekiswa nezinye iimodyuli, ziqinisekisa ukusebenza kakuhle kokuguqulwa kwamandla kwiimeko ezahlukeneyo zokufakela. Olu phawu luphucula ukuguquguquka kunye nokuguquguquka kweephaneli zeCdTe kwizicelo zeBIPV.
8. Iingenelo zokusingqongileyo kunye nozinzo
Iglasi yelanga yeCdTe yenziwa kusetyenziswa izixhobo kunye neendlela ezinobuhlobo nokusingqongileyo, ezihambelana neenjongo zophuhliso oluzinzileyo.
