Presented at: 29th IEEE Photovoltaic Specialists Conference, New Orleans, USA, 20-24 mei 2002.
Abstract:
Multicrystalline silicon solar cells produced with double side emitterdiffusion are compared with single side emitter diffused cells. Double
side emitter diffusion yields in improved current and voltage for all
materials of four multicrystalline silicon wafer suppliers. Poor quality
material improves
approximately 3% more than good quality material. This results in a
narrower efficiency distribution over all material. NO relation between
substitutional carbon concentration, interstitial oxygen concentration
and FeB concentration and improved current due to double side diffusion
was found.
