Techno-Economic and Sensitivity Investigation of a Novel Perovskite Solar Cells Based High Efficient Hybrid Electric Sources for Off-Shore Oil Ships.

Herein, this study presents for the first time third generation perovskite solar cells (PSCs) for enhancing the performance of off-shore oil ships. The off-shore oil ships need a high efficient hybrid solar energy- batteries system for enhancing the ships efficiency and reduce the pollutants resulting from these ships. In this study, an efficient model that consists of hybrid renewable energy system (HRES) suitable for the off-shore oil ships is presented and discussed. The model uses the PSCs as a solar energy source thanks to their high efficiency reaching now almost 26% based on nanotechnology in fabrication process. For determining the optimum quantities of the HRES model the HOMER software was used. The model succeeded in reducing the pollutants and the greenhouse gases (GHGs). The direction of the ship under study is from Dalian in China to Hurghada in Egypt where the data of electric load was chosen based on this journey which is real data. The full components of the model used are PSCs, Batteries and Diesel engine. Two PSCs arrays with 600 kW and 900 kW were used in the study beside 600 kW silicon based solar cells array for comparison between technologies of solar cells. The PSCs array were formed based on a laboratory fabricated PSCs that have 23.5 mA. Cm-2 as a short circuit current density, 1.085 V as open circuit voltage, 0.79 as a fill factor and 20.05% as a power conversion efficiency. The results revealed that the suggested model can help in reducing the total fuel consumption and the GHGs by 5,765,575 L and 15,592,017 kg for 600 kW silicon, 15,177,375 L and 15,662,875 kg for 600kW PSCs case, 17,634,350 L and 22,307,325 kg for 900kW PSCs case respectively related to using only diesel generator during the ship journey under the same conditions. Based on the obtained results, using the solar cells especially the recent technology base ones is attractive and highly recommended on the off-shore oil ships. This leading to both the fuel consumptions and cost reduction.
