In this work, the effect of doping concentration of Ag and Cu in both thermal and laser anneal process of doping to CdTe thin film solar cells� electrical performance were investigated. CdTe thin films of 3 �m thickness were deposited using the close-spaced sublimation (CSS) process and subjected to Cu and Ag doping process through dip coating in copper (II) chloride (CuCl2) and silver nitrate (AgNO3) solution, respectively at different concentration range followed by either thermal or laser annealing. Thermally annealed CdTe thin films were treated in convection oven, whereas laser annealing was carried out by illuminating the samples with pulsed neodymium-doped yttrium aluminium garnet (Nd:YAG) laser at wavelength of 532 nm. Fabricated solar cells were electrically characterized by light current-voltage (J-V) and capacitance-voltage (C-V) measurements. J-V measurement demonstrates that Cu doped CdTe solar cells are having better electrical performance as compared to Ag doped ones. The effect of increasing dopant solution concentrations seems to have consistent trend with the increase of J-V parameters as identified in this work. C-V measurement shows that Cu doped CdTe films has higher doping capability with the highest acceptor concentration of 1.5 � 1014 cm?3 compared to Ag doped CdTe films of 8.1 � 1013 cm?3. In addition, laser annealing finds lower J-V performance and acceptor concentration of Cu and Ag doped CdTe solar cells with limitations in smaller process space for surface annealing as well as optimization. � 2018 Elsevier Ltd Final 2023-05-29T06:51:01Z 2023-05-29T06:51:01Z 2018 Article 10.1016/j.solener.2018.07.009 2-s2.0-85050290790 https://www.scopus.com/inward/record.uri?eid=2-s2.0-85050290790&doi=10.1016%2fj.solener.2018.07.009&partnerID=40&md5=f25bbd07b95c9c0daff455af5071ad37 https://irepository.uniten.edu.my/handle/123456789/23684 173 1 6 Elsevier Ltd Scopus |
