Solar cells are devices that directly convert the sunlight into electricity by photovoltaic effect. Photovoltaic effect was discovered in 1839 by Bequerel. In recent years, different generations of solar cells have been developed. There are different types of solar cells including silicone solar cells, dye-sensitized solar cells, quantum dot solar cells, organic solar cells and new generations. Among different kinds of solar cells, polymer solar cells have attracted a lot of attention because of their flexibility, light weight, possibility of designing of materials for their construction, high absorption coefficient, solution processability and production by low-cost technologies. In this review, polymer solar cells and conjugated conductive polymers as applied in active layers and their characteristics as conjugated polymers are introduced. In recent times advances are made on active layer architecture in order to increase power conversion efficiency. Finally, their corresponding characterization methods and their most important parameters are discussed.
