Abstract :
Fluorine tin oxide (SnO2:F)/silicon ( on both n and p type) junctions are prepared at 375°C by a simple deposition technique called electrostatic spray prolysis (ESP). The SnO2:F/p-Si yielded to an ohmic contact. The photovoltaic behavior of SnO2:F/n-Si junctions as functions of oxidation time tOX is reported in the present paper with the view to understanding the role of the interfacial oxide layer in the photovoltaic process. The junctions have been characterized by I(V) and C(V) measurements. A maximum efficiency of 6.2% is observed (under 80 mw.cm-2 illumination) of SnO2:F/n-Si junctions at an oxidation time of 30s. The junctions are observed to be quite stable with time
