Advanced solar cell contacts feature local contacts to pand pSi. In this review existing models for contact formation to p and p The formation of the local Al BSF as applied in PERC like solar cell structures is inhibited by the formation of voids. It is shown that the formation of voids depends on process parameters and their influence on the contact formation is reviewed. Using an analytical ...

2014 The effects of very thin Ag surface layers on the propagation of surface plasma waves (S.P.W.) excited by ATR at an Al surface are investigated in the vicinity of the Ag plasma frequency and the S.P.W. dispersion relations, are obtained. A splitting of the dispersion curves is found for Ag layers 26, 39 and 58 Å thick, but does not appear for thinner layers. Experimental and computed dispe...

This work is mainly focused on an alternative method for emitter formation by means of boron diffusion from a boron-doped plasma-enhanced chemical vapor deposition (PECVD) doping source. With this approach only one high temperature process is necessary for emitter and BSF/FSF formation (co-diffusion), without depletion of surface doping concentration. This enables time and cost-efficient fabric...

2014 The optical properties of very thin Ag layers on Al surfaces were investigated in the vicinity of the Ag effective plasma frequency, by attenuated total reflection with surface plasma wave excitation. The complex dielectric constant of the adsorbed layers is found to be similar to that of bulk Ag provided non-local effects (longitudinal plasma waves) are taken into account. LE JOURNAL DE P...
