In order to reduce energy consumption and meet the manufacturing needs of flexible devices,it is very important to prepare inorganic perovskite solar cells (PSCs) materials at a low temperature (≤200℃). Research progress in preparation of inorganic PSCs materials at a low temperature is reviewed.The methods for preparing inorganic PSCs materials at low temperature are summarized.Finally,the prospects of the preparation of inorganic PSCs materials at a low temper...
