Ukuphucula ukusebenza kakuhle kweemodyuli kunye nokwandisa amandla okuvelisa kudlala indima encedisayo ekunciphiseni iindleko zeemodyuli ze-metal halide chalcogenide/silicon stacked solar. Abaphandi beSebe le-US Department of Energy's National Renewable Energy Laboratory (iSebe le-US Department of Energy's National Renewable Energy Laboratory, NREL) babonise ukuba: i-leverage nganye yeendleko inokudlala indima efanayo, kuxhomekeke kubuchule bomenzi bokwandisa nokuphucula ukusebenza kwemodyuli.
Uninzi lweemodyuli ze-photovoltaic (PV) ezenziweyo namhlanje zisekelwe kwiiseli zelanga ze-silicon ezihlangeneyo, kwaye ngokuhlanganisa i-silicon nezinye izinto zeseli zelanga (ezifana ne-metal halide) ukwenza i-stack ye-chalcogenides (MHPs), abavelisi banokwenza iimodyuli zelanga. Oku kunokuguqula ukukhanya kwelanga okuninzi kube ngumbane kune-silicon yodwa. Le teknoloji yokufaka i-stacking isekwizigaba zayo zokuqala, kwaye kukho iindlela ezahlukeneyo ezifunwayo zokudibanisa ii-MHP, ezininzi ezingaziwayo malunga neendleko kunye nokusebenza. Ukujongana nale ngxaki, abaphandi bakhe imodeli yeendleko zokuvelisa eza kusebenzisa izixhobo ezikhoyo kunye neenkqubo zelebhu yokuhambisa umbane ukuthelekisa iindlela ezahlukeneyo ezinokwenzeka kwinqanaba.
Abaphandi bahlolisise iindlela ezahlukeneyo zokwakha iimodyuli ezihlanganisiweyo baza bathelekisa uvakalelo lweendleko zokuvelisa nezinto ezisetyenziselwa ukuzenza, inani leeleya zezixhobo, iindleko zokwenza izixhobo, indawo yefektri, kunye nezinye izinto. Bafumanise ukuba izinto ezinefuthe elikhulu kwiindleko zokuvelisa yayikukusebenza kwefektri kunye nokusebenza kakuhle kweemodyuli.
"Omnye wemibuzo ephendulwa leli phepha ngulo: lithini ixabiso lale ndlela yokusebenza kakuhle?" UJacob Cordell, umbhali ophambili wephepha elithi "Uhlalutyo lwezobuchwephesha lwe-perovskite/silicon tandem solar modules," elipapashwe kwijenali iJoule, utshilo. "Into ebalulekileyo ekufuneka uyithathe kukuba i-2.5% ye-absolute efficiency gain kwiimodyuli inika ukunciphisa iindleko okufanayo ngeyunithi nganye yomthamo njengokuphinda kabini ubukhulu besityalo."
Besebenzisa iDetailed Cost Analysis Model (DCAM) ekhoyo ngoku, abaphandi bakwazile ukuvavanya iimeko ezahlukeneyo, kuquka ukufumana izityalo kwiindawo ezahlukeneyo zehlabathi kunye neentlobo ezahlukeneyo zezibonelelo zokwenza imveliso. Ngokusebenzisa imodeli, iinkampani kunye nabaphandi banokusebenzisa esi siseko ukuhlola indlela iinkqubo ezahlukeneyo kunye nezixhobo ezichaphazela ngayo iindleko. Le modeli ayijongani nokuveliswa kwamandla okanye ubomi bezi modyuli, eziziindawo ezisebenzayo zophando.
Ukuqala ngemodeli esisiseko yomenzi owenza iimodyuli ngendlela esebenza kakuhle ngama-25 ekhulwini, enomthamo wonyaka wemveliso we-3 gigawatts e-US, abaphandi bathelekise ukusebenza kakuhle kunye nemveliso ukuze babone indlela iindleko zeemodyuli ezitshintsha ngayo njengoko ubungakanani bamandla avelisiweyo busanda. "Oku kubonisa amandla ophando ekuphuculeni ukusebenza kakuhle kwezixhobo kunye nokunciphisa iindleko nge-watt nganye yeemodyuli," utshilo uCordell.
Inqaku lejenali, elibhalwe nguMichael Woodhouse no-Emily Warren, liphawula ukuba ukusebenza kakuhle kweemodyuli lutshintsho oluguquguqukayo ekuqikeleleni ixabiso leemodyuli ezihlanganisiweyo kuba ezinye izinto ezininzi eziguquguqukayo zitshintshile kwaye ziya kuqhubeka zitshintsha ukuze zikwazi ukufikelela kumanqanaba okusebenza kakuhle kunye nokuqina okufunekayo kwi-PV ethengiswayo. Iimodyuli ezihlanganisiweyo kufuneka zibe nokusebenza kakuhle ubuncinane nge-25% ukuze zikwazi ukukhuphisana ngamaxabiso kwaye zisetyenziswe nezinye iiteknoloji zelanga. Inyathelo elilandelayo ekuthengisweni kweemodyuli ezihlanganisiweyo ze-chalcogenide/silicon kukuphucula ukuthembeka kwetekhnoloji kunye nokwandisa indawo yezixhobo ezisebenzayo ukuya kubungakanani obupheleleyo beemodyuli ngelixa kugcinwa ukusebenza.
