Ukuthuthukisa ukusebenza kahle kwamamojula nokwandisa amandla okukhiqiza kudlala indima ehambisanayo ekunciphiseni izindleko zamamojula elanga e-halide chalcogenide/silicon stacked. Abacwaningi be-US Department of Energy's National Renewable Energy Laboratory (US Department of Energy's National Renewable Energy Laboratory, NREL) baveze ukuthi: i-leverage ngayinye yezindleko ingadlala indima efanayo, kuye ngokuthi umenzi uyakwazi yini ukwandisa nokuthuthukisa ukusebenza kwemojula.
Amamojula amaningi e-photovoltaic (PV) akhiqizwa namuhla asekelwe kumaseli elanga e-silicon ahlanganayo, futhi ngokuhlanganisa i-silicon nenye into yeseli lelanga (njenge-halide yensimbi) ukuze kwakheke inqwaba yama-chalcogenides (MHPs), abakhiqizi bangakha amamojula elanga. Lokhu kungashintsha ukukhanya kwelanga okuningi kube ugesi kune-silicon yodwa. Lobu buchwepheshe bokufaka ama-stacking busesezigabeni zokuqala, futhi kunezindlela ezahlukahlukene ezifunwayo zokuhlanganisa ama-MHP, okungaziwa okuningi ngokwezindleko nokusebenza. Ukuze kuxazululwe leli gebe, abacwaningi bakhe imodeli yezindleko zokukhiqiza ezosebenzisa amadivayisi akhona kanye nezinqubo zelebhu yokuhlinzeka ukuze kuqhathaniswe izindlela ezahlukene ezingaba khona ngezinga.
Abacwaningi bahlole izindlela ezahlukene zokwakha amamojula ahlanganisiwe futhi baqhathanisa ukuzwela kwezindleko zokukhiqiza nezinto ezisetshenziswa ukuwakha, inani lezingqimba zamadivayisi, izindleko zokukhiqiza amadivayisi, indawo yefektri, nezinye izici. Bathole ukuthi izici ezazinomthelela omkhulu ezindleleni zokukhiqiza kwakuwukusebenza kwefektri kanye nokusebenza kahle kwamamojula.
"Omunye wemibuzo ephendulwa yileli phepha uthi: liyini inani lalokhu kusebenza kahle?" kusho uJacob Cordell, umbhali oholayo wephepha elithi "Technoeconomic analysis of perovskite/silicon tandem solar modules," elanyatheliswa ephephabhukwini iJoule. "Into ebalulekile okufanele uyikhumbule ukuthi inzuzo yokusebenza kahle engu-2.5% kumamojula ihlinzeka ngokunciphisa izindleko okufanayo ngeyunithi ngayinye yamandla njengokuphinda kabili ubukhulu besitshalo."
Besebenzisa i-Detailed Cost Analysis Model (DCAM) etholakala emphakathini manje, abacwaningi bakwazile ukuhlola izimo ezahlukahlukene, okuhlanganisa ukuthola izitshalo ezingxenyeni ezahlukene zomhlaba kanye nezinhlobo ezahlukene zezikhuthazo zokukhiqiza. Ngokusebenzisa imodeli, izinkampani nabacwaningi bangasebenzisa lesi sisekelo ukuhlola ukuthi izinqubo nezinto zokwakha ezahlukene zithinta kanjani izindleko. Imodeli ayibheki ukukhiqizwa kwamandla noma isikhathi sokuphila kwalezi modyuli, okuyizindawo ezisebenzayo zocwaningo.
Beqala ngemodeli eyisisekelo yomkhiqizi owenza amamojula ngokusebenza kahle kwamaphesenti angama-25, enomthamo wokukhiqiza waminyaka yonke wama-gigawatts ama-3 e-US, abacwaningi baqhathanisa ukusebenza kahle kanye nesivuno sokukhiqiza ukuze bathole ukuthi izindleko zamamojula ziyahlukahluka kanjani njengoba inani lamandla akhiqizwayo likhuphuka. "Lokhu kubonisa amandla ocwaningo ekuthuthukiseni ukusebenza kahle kwedivayisi kanye nokunciphisa izindleko nge-watt ngayinye yamamojula," kusho uCordell.
Isihloko sephephabhuku, esibhalwe nguMichael Woodhouse no-Emily Warren, siphawula ukuthi ukusebenza kahle kwamamojula kuyinguquko eguquguqukayo ekubikezeleni izindleko zamamojula ahlanganisiwe ngoba ezinye izinto eziningi eziguquguqukayo zishintshile futhi zizoqhubeka nokushintsha ukuze zikwazi ukufeza amazinga okusebenza kahle nokuqina adingekayo kwi-PV ethengiswayo. Amamojula ahlanganisiwe kumele okungenani abe nempumelelo engu-25% ukuze ancintisane ngentengo futhi asetshenziswe nezinye ubuchwepheshe belanga. Isinyathelo esilandelayo ekuthengisweni kwamamojula ahlanganisiwe e-chalcogenide/silicon ukuthuthukisa ukuthembeka kobuchwepheshe nokwandisa indawo yamadivayisi asebenzayo abe usayizi ogcwele wamamojula ngenkathi kugcinwa ukusebenza.
