Photovoltaic Effect and Efficiency of Perovskite Solar Cells

Recently, the solar cells have become a hotspot as the solar power is becoming more and more popular. There are many types of solar cells. Perovskite solar cells (PSCs), as a type of solar cell, use perovskite type semiconductors as the light absorbing materials. PSCs exhibit high efficiency and stability. The performance of solar cells could be evaluated by the photovoltaic effect. Therefore, the research on the photovoltaic effect of perovskite solar cells is of importance. This essay gives a brief introduction to the composition and structure of perovskite solar cells. Then, it introduces the photovoltaic effect of perovskite solar cells in two parts which include working principle and efficiency of PSCs. In order to further elucidate the mechanism of PSCs, the influencing factors of photovoltaic effect are discussed. Meanwhile, the limitations and challenges of perovskite solar cells are outlined. Besides, the future development trend regarding these issues is outlined. This work will help to promote further development of this field.
