Due to the destructive effects of fossil fuels on the environment, using renewable energies has nowadays been suggested. In addition, because of the increased use of solar energy and the prevention the solar cell supply chain (SCSC), this chain is mainly supported by government funding. In this study, we mathematically model both supply-side and demand-side policies for a two-echelon SCSC, considering the competition between domestic and foreign suppliers as well as government intervention under the supply-side subsidy policies to support SCSC members and finance the customers through demand-side subsidy policies. The aim of this paper is to investigate the effects of government intervention under the supply-side and demand-side policies on supporting the members of SCSC and encouraging customers to increase the use of solar panels. In addition, this study explores the best policy for improving and promoting SCSC. In the real world, both supply-side and demand-side policies will help industrial factories, power plants, and households to enhance the use of solar energy for producing electricity. This study has been investigated using one real example, whose results show that the efficiency under the supply-side policy is about 7% more than the efficiency under the demand-side policy. The price under the supply-side policy is roughly 10% less than the price under the demand-side policy. The members' profit under the supply-side policy is approximately 5% bigger than the one under the demand-side policy. According to real examples, the government's utility under the demand-side policy is nearly 1% smaller than the government's utility under the supply-side policy. Finally, key findings are considered for the proposed model.
由于化石燃料对环境的破坏作用，如今有人建议使用可再生能源。此外，由于太阳能使用量的增加以及对太阳能电池供应链（SCSC）供应的保障，该供应链主要由政府资金支持。在本研究中，我们对两级SCSC的供应侧和需求侧政策进行了数学建模，考虑了国内外供应商之间的竞争以及供应侧补贴政策下的政府干预，以支持SCSC成员并通过需求侧补贴政策为客户提供资金。本文的目的是研究供应侧和需求侧政策下政府干预对支持SCSC成员以及鼓励客户增加太阳能板使用的影响。此外，本研究还探索了改善和促进SCSC的最佳政策。在现实世界中，供应侧和需求侧政策都将有助于工业工厂、发电厂和家庭提高太阳能发电的使用。本研究使用了一个实际例子进行调查，其结果表明，供应侧政策下的效率比需求侧政策下的效率高约7%。供应侧政策下的价格比需求侧政策下的价格低约10%。供应侧政策下成员的利润比需求侧政策下的利润大约高5%。根据实际例子，需求侧政策下政府的效用比供应侧政策下政府的效用小近1%。最后，对所提出的模型考虑了关键发现。
