The perovskite solar cells have developed in a very fast speed for their excellent photovol- taic performance and low cost. The structure and basic operating principle of the perovskite solar cells are briefly introduced. The research progress of the hole-transport material （HTM） -free layer perovskite solar cells with the further simplifies structure, preparation process and the lower cost are mainly discussed. The study of ion modification of the absorption layer in HTM-free perovskite solar cells are introduced, which could improve the absorption spectrum, power-conversion efficiency and the stability of the solar cells, by the ion modification of the absorption layer. The heterojunction, metal-semiconductor contacts and operation principle of the HTM-free perovskite solar cells are reviewed, and the significance and de- velopment status of the role of carbon and nickel back electrode in HTM-free perovskite solar cells are in- troduced. The research progress of the plane heterojunction structure and sensitization of quantum dots in HTM-free layer perovskite heterojunction solar cells are briefly introduced.
