Recent Advances in the Development of Organic Solar Cells and Perovskite Solar Cells

Organic and Perovskite Solar Cells (OSCs and PSCs) are based on solution-processable semiconductors, whereas Si-based Solar Cells (SSCs) are based on silicon wafers, which require costlier pure silicon materials because of their high-temperature production. OSCs are light in weight and environmentally friendly. In addition, researchers found that light absorbers were available in a wide range of colors. In contrast, PSCs yielded higher conversion efficiency due to excellent charge-carrier mobilities, lifetime and light absorption. In this work, various types of techniques have been used to study the properties of the prepared materials. The obtained results showed that photovoltaic parameters are strongly depending on experimental conditions.
