Method of fabrication of solar cells is similar to the manufacturing of IC (integrated circuit) and silicon wafer used in computers due to its high refinements. However, high manufacturing cost and difficulties in process are the reason for searching alternative technologies. Few advantages of polymer PV cells compared to silicon PV cells are less weight, less production cost, environmental friendly, and disposable. Polymer PV cells are highly transparent, and it can be used in doors, windows, and electronics; however, it offers 33% of efficiency compared to silicon solar cells; it also undergoes chemical degradation due to solar light and it has lower stability [1, 17]. Owing to tandem structure, polymer solar cells can achieve 10% efficiency as shown in Figure 2.10 [8, 16].
