A doubled sided buried contact silicon solar cell (BCSC) structure is currently being developed at the University of New South Wales. It is based on the conventional buried contact structure (Wenham, 1986) with the added advantages of potentially higher conversion efficiency and lower production cost. The use of mechanical scribing rather than laser scribing to form the grooves in the silicon substrate has no detrimental effect on the performance of the device and may have the potential to significantly reduce production costs. A DPX-3500 drafting plotter has been adapted to serve as a mechanical scriber. This paper presents the promising results obtained on the new structure.

In this paper, we investigate the effect of double-sided buried metallicontacts (BMCs) on the photovoltaic performances of polycrystalline-silicon (pc-Si) solar cells. Prior to junction formation, groove patterns were achieved on both surface sides of the pc-Si wafers using a chemical vapour etching
Residual deformations of the silicon lattice following laser scribing have been shown to be present in the grooved region of buried-contact silicon solar cells. A freshly cleaved surface perpendicular to the phosphorus-diused laser-scribed grooves has been used in conjunction with an electron beam-i
Tri-crystalline silicon wafers have been used for fabrication of buried contact solar cells. Optical properties and microstructures after texturing in KOH solution have been studied and compared with those of multi-crystalline silicon wafers. The textured surface of tri-crystalline wafer has a shape
