    Feasibility study of floating solar photovoltaic systems using techno-economic assessment and multi-criteria decision-making method: A case study of Bangladesh
    (Elsevier Ltd, 2024-11-30) Sunny, M.R.,,, ,; Kabir, M.A.; Sarker, M.S.Z.; Aghaloo, K.; Ali, T.
    Many developing countries with abundant solar resources and rich history of agriculture, face overpopulation and land shortage issues. Floating solar photovoltaics (FSPVs) do not compete with agriculture for land and offer higher energy potential than land-based photovoltaics (LBPVs). For feasibility and site suitability evaluation of FSPVs, this study proposes an integrated approach of techno-economic assessment (TEA) and multi-criteria decision making (MCDM), based on a case study of Bangladesh. The system advisor model (SAM) was used to conduct TEA, evaluating the potential of nine FSPV sites on a regional scale using ten criteria. Combined compromise solution (CoCoSo) was implemented to determine the optimum site. Bergobindopur lake was ranked top, with the highest energy yield and lowest cost of energy of 1564 kWh/kW and $0.055/kWh respectively. Case study of Bergobindopur revealed buy-all-sell-all electricity tariff was more profitable than net billing and net metering. Energy generation was found to be influenced by tilt angle and soiling. Sensitivity analyses demonstrated the superiority of FSPVs over LBPVs for varying electricity prices, degradation and discount rates, project durations, and investor's equities. Longer project durations and lower equities resulted in higher profits for investors. The proposed approach contributes to the expansion of FSPV in land-constrained areas. © 2024 Elsevier Ltd

    Numerical modeling and analysis of ultra thin film Cu(In, Ga)Se2 solar cell using SCAPS-1D
    (Institute of Electrical and Electronics Engineers Inc., 2017-03-06) Robin, M.S.R.,; Rasmi, M.M.M.,; Sarker, M.S.Z.; Rabbi Al Mamun, A.S.M.
    This paper exhibits a numerical analysis of ultra thin film Cu(In, Ga)Se2 (CIGS) solar cell which has been performed by using SCAPS-1D simulator. In this paper, the performances of CIGS solar cell is observed by varying absorber layer, buffer layer and window layer thickness. Also the effect of temperature has been carried out. The aim of this work is optimization of CIGS solar cell thickness as well as the efficiency. Results represent that solar cell performances have enhanced with rise in thickness of CIGS absorber layer. Meanwhile opposite scenario is found with the rise in buffer layer and window layer thickness. The highest cell efficiency achieved is 22.67% with 0.7862 V open circuit voltage (Voc), 34.130 mA/cm2 short circuit current density (Jsc) and 84.49% Fill Factor (FF) on 2000 nm CIGS absorber layer.
