The development of renewable energy is vital to modern life due to the challenges from the depletion of fossil energy, the greenhouse effect and the deterioration of the environment. The third generation of solar cells including dye-sensitized solar cells, perovskite solar cells and organic polymer solar cells, are characterized by high conversion efficiency, low processing cost and environmental friendliness, they have attracted tremendous scientific and industrial attention in the past two decades. It is greatly significative to improve the efficiency and stability of solar energy devices for promoting their industrialization. Metal organic framework materials (MOFs) is a new kind of compound arranged with metal clusters and organic monomers, which is widely studied in the field of gas storage and separation. In recent years, MOFs is also used in photovoltaic technology to improve the incident photon-to-electron conversion efficiency and stability of device due to its high crystallinity, huge specific surface area and porosity. The review focuses on the summary of the applications and breakthroughs of MOFs and their derivatives in dye-sensitized solar cells, perovskite solar cells and organic polymer solar cells in recent years, aiming to provide references for the prospect of photovoltaic technology in the future.
