Book excerpt: In this work, we have developed thin layers deposited by Atomic Layer Deposition (ALD) technique to be applied in high-efficiency crystalline silicon solar cells. In particular, we selected to study the aluminium oxide (Al2O3) as a surface passivation mechanism and the titanium dioxide (TiO2) as a selective contact for electrons. To characterize the Al2O3 we have done two studies: deposition thickness and pre-deposition cleaning process. In both studies we have measured the effective surface recombination velocity (Seff), where we get results comparable to the state of the art with Seff
