TY - JOUR ID - TI - Heterojunction Solar Cell Based on Highly-Pure Nanopowders Prepared by DC Reactive Magnetron Sputtering AU - Saja H. Faisal PY - 2020 VL - 16 IS - 3 SP - 27 EP - 32 JO - Iraqi Journal of Applied Physics المجلة العراقية للفيزياء التطبيقية SN - 18132065 23091673 AB - In this work, a novel design for the NiO/TiO2 heterojunction solar cells is presented. Highly-pure nanopowders prepared by dc reactive magnetron sputtering technique were used to form the heterojunctions. The electrical characteristics of the proposed design were compared to those of a conventional thin film heterojunction design prepared by the same technique. A higher efficiency of 300% was achieved by the proposed design. This attempt can be considered as the first to fabricate solar cells from highly-pure nanopowders of two different semiconductors.
