چکیده انگلیسی
In this paper, we have studied the effect of rapid thermal annealing on the optical properties of porous silicon layers doped with lithium (Li/PS). Surface modification of As-deposited Li/PS samples through thermal annealing were investigated by varying the temperature from 100 °C to 800 °C in an infrared (IR) heated belt furnace. A decrease in the reflectivity to about 6% for Li/PS annealed at 200 °C was obtained. From Photoluminescence (PL) spectra, a blue-shift of the gap was observed when the temperature is increased to 800 °C; we correlate these results to the change in chemical composition of the layers in order to find the optimized conditions for a potential application in silicon solar cells.
