In recent years, the sun has been used as one of the main sources of renewable energy and supplying energy through solar cells has been quickly increased. This paper develops a two-echelon multi-period multi-product solar cell supply chain (SCSC) with three scenarios including (1) The presence of domestic supplier in a monopoly market, (2) The arrival of a foreign rival to the competitive market, and (3) The government intervention in a competitive market. Three scenarios under non-cooperative Nash game are modeled and formulated for two types of solar cells, dye-sensitized and perovskite. The obtained solutions of three scenarios from the game models are put in a mathematical model for a solar cell powerhouse. In this multi-period multi-product mathematical model, the degradation of the solar cells is considered. In the meantime, solar cell powerhouse as one of the end-users of solar energy deals with the degradation by substitution solar panels. The proposed model determines how many solar panels/modules from two kinds of it should be installed and substituted in each period and which scenario to be selected. Finally, it is represented a numerical example, sensitive analysis, and management insights for the proposed model. (C) 2019 Elsevier Ltd. All rights reserved.
