BP Solar had previously studied anti-reflective (AR) coated glass from several different manufacturers under extensive accelerated environmental testing and found a 2.4 to 3.0% increase in output power at STC (Standard Test conditions) for both BP Saturn 7-Series (Saturn mono-) and BP Poly 3-Series (multi-) crystalline silicon PV modules. The AR coating changes the front surface reflection in a manner which is both Angle of Incidence (AOI) and wavelength dependent and thus the outdoor gain will depend on the prevailing meteorological conditions.
The laser-grooved buried contact (LGBC) crystalline silicon solar cell has a selective emitter with excellent response to the solar spectrum in the wavelength range 300-900 nm. However, the cell efficiency is limited by a reduced response in the 900-1200 nm region of the spectrum due to the high recombination characteristics of the rear aluminium back surface contact and reduced internal reflection at this interface. The LGBC cell has now been fabricated with an aluminium laser-fired contact (LFC) through a passivating rear silicon oxide dielectric.
