These films have the distinctive properties that they can provide excellent surface passivation, are easily patterned using photolithography and wet chemical etching, and are compatible with aluminium layers for a back surface optical reflector. Cells with planar surfaces and random pyramid texturing have been fabricated. Open circuit voltages up to 667mV have been measured on float-zone substrates and 655mV on multicrystalline material, proving the outstanding surface passivation provided by the silicon nitride films. Conversion efficiencies of 18.5% and 16.1% have been obtained respectively.91654 bytes364 bytesapplication/pdfapplication/octet-streamen-AUsilicon-nitridepassivationc-SiSimplified PERC solar cells passivated with PECVD silicon nitride2000
