This work shows the fabrication of Bi2O3/PSi heterojunction for solar cell applications prepared by simple chemical method. Bi2O3 nanoparticles were deposited on the n-type porous silicon and glass substrates by drop casting method. The structural and optical properties of bismuth oxide thin film were studied by XRD, SEM, UV-VIS and FTIR analysise. XRD investigation showed that the thin film is polycrystalline and the optical properties stated that bismuth oxide thin film has direct optical band gap of 2.5 eV in addition to the study of I-V in dark and under illumination and finally. The results indicate a significant improvement in the properties of porous silicon, and thus an increase in the conversion efficiency, as the calculated efficiency values for (Al/Bi 2 O 3 /PSi/Si/Ag) heterojunction.
