Since 2009, halide perovskite which shows excellent semiconductor properties, relatively low cost, and great potential in applications of solar cell start to attract numerous focuses from academia and industry. Up to now the highest PCE could exceed 29% and it is quite close to the theoretical highest efficiency. However, the efficiency of it is still confined by practical obstacles and long-time stability. It shows that train mechanism would be a key factor to improve the performance of halide perovskite devices. In this review, basic principles and factors about strains would be talked about, and some methods to make use of strain materials would be introduced.
