Ukuqondiswa kokuthuthukiswa kobuchwepheshe be-silicon cell cell kuhlanganisa nobuchwepheshe be-PERT kanye nobuchwepheshe be-Topcon, lobu buchwepheshe buthathwa njengesandiso sobuchwepheshe beselula bendlela yokusabalalisa, izici zabo ezivamile ungqimba lwe-passivation ohlangothini olungemuva lweseli, futhi zombili zisebenzisa ungqimba lwe-silicon ye-doped njengenkundla engemuva, isikole sisetshenziswa kakhulu ekushiseni okuphezulu oxidized ungqimba we-silicon oxidized ungqimba lwe-doLPD oxidized ungqimba lwe-silicon esetshenziswa ungqimba lwe-doLPD. I-PECVD, njll. I-Tubular PECVD ne-Tubular PECVD ne-flat plate PECVD kusetshenziswe ekukhiqizweni kwesisindo esikhulu samaseli e-PERC.
I-Tubular PECVD inomthamo omkhulu futhi ngokuvamile isebenzisa ukunikezwa kwamandla wefrikhwensi ephansi amashumi amaningana e-kHz. Ukuqhuma kwe-ion kanye nezinkinga ze-bypass plating zingathinta ikhwalithi yesendlalelo sokudlula. Ipuleti eliyisicaba i-PECVD ayinayo inkinga ye-bypass plating, futhi inenzuzo enkulu ekusebenzeni kwe-coating, futhi ingasetshenziselwa ukubekwa kwamafilimu e-doped Si, Si0X, SiCX. Okubi ukuthi ifilimu ehlanganisiwe iqukethe i-hydrogen eningi, kulula ukubangela ukuqhuma kwesendlalelo sefilimu, elinganiselwe ebukhulu be-coating. lpcvd coating ubuchwepheshe usebenzisa tube isithando enamathela, nge umthamo omkhulu, kungaba ukufaka ifilimu polysilicon ujiyile, kodwa kuyoba khona eduze Plating kwenzeka, inqubo lpcvd ngemva ukususwa emhlabeni Plating of the ungqimba ifilimu futhi akulimazi ungqimba phansi. Amaseli e-Topcon akhiqizwe ngobuningi azuze ukuguqulwa okuyisilinganiso sokusebenza kahle kwama-23%.
