Abstract: The review provides calculation methods for the cost per watt and levelized cost of energy of perovskite photovoltaic modules.Combining with the production technology routes of perovskite photovoltaic modules, the paper discusses and calculates the cost per watt of perovskite photovoltaic modules by considering material costs,production line costs, and depreciation of production lines during manufacturing. Additionally,the levelized cost of energy of perovskite photovoltaic modules is calculated and forecasted. A comparative analysis is conducted between the levelized cost of energy of perovskite photovoltaic modules and those of thermal power,hydroelectric power,and wind power, aiming to provide valuable insights for enterprises and research institutes engaged in the manufacture of perovskite photovoltaic modules.
