Abstract :
We have prepared double SiO2/TiO2 anti-reflection layers to be applied on silicon solar cells by means of an inexpensive technique based on the spin-on deposition of sol-gel solutions. Experimentally we show that by using bi-layers with 647 Å of TiO2 and 1064 Å of SiO2 we can reduce the reflection losses below 4% for the whole AM 1.5 solar spectrum.
