Kutungamira kwecrystalline silicon cell tekinoroji kusimudzira kunosanganisirawo PERT tekinoroji uye Topcon tekinoroji, aya matekinoroji anoonekwa sekuwedzera kwechinyakare diffusion nzira sero tekinoroji, hunhu hwawo hunozivikanwa ndeye passivation layer kuseri kwesero, uye ese ari maviri anoshandisa layer yedoped poly silicon senzvimbo yekumashure, chikoro chinoshandiswa zvakanyanya mukupisa-tembiricha oxidized muchidimbu chesilicon uye chidimbu chinoshandiswa nesilicon yeCVD. PECVD, etc. Tubular PECVD uye Tubular PECVD uye flat plate PECVD yakashandiswa muhukuru-hukuru hwekugadzirwa kwemasero ePERC.
Tubular PECVD ine hukuru hukuru uye kazhinji inotora yakaderera-frequency magetsi emakumi akati wandei kHz. Ion bombardment uye bypass plating matambudziko anogona kukanganisa kunaka kweiyo passivation layer. Flat plate PECVD haina dambudziko rebypass plating, uye ine mukana wakakura mukuita coating, uye inogona kushandiswa kuisa doped Si, Si0X, SiCX mafirimu. Izvo zvisingabatsiri ndezvokuti firimu rakaputirwa rine yakawanda yehydrogen, iri nyore kukonzera blistering yefirimu layer, inogumira muhupamhi hwekuputira. lpcvd coating tekinoroji uchishandisa chubhu choto coating, ine hukuru hukuru, inogona kuisa gobvu repolysilicon firimu, asi pachange paine kutenderedza plating kunoitika, mune lpcvd maitiro mushure mekubviswa kwekutenderedza plating yefirimu layer uye haina kukuvadza pasi pasi. Maseru-akagadzirwa eTopcon maseru akawana avhareji yekushandura inoshanda ye23%.
