Method for calculating power generation cost of perovskite solar cell

Abstract

The invention relates to a method for calculating the power generation cost of a perovskite solar cell. The method comprises the following steps: calculating the perovskite cell kilowatt-hour cost COE: calculating the value of total expenditure converted from the ith year to the beginning in the life cycle of a photovoltaic power station, and equally dividing the total investment cost of the photovoltaic power station and the total power generation capacity in the life cycle to obtain the average cost at any moment in the life cycle; calculating the initial investment I0 of the power station;calculating the expenditure Ii of the ith year in the service life of the power station; calculating the generating capacity Ei of the ith year in the service life of the power station. The beneficialeffects of the invention are that: the method is suitable for large-scale production; according to the method, the manufacturing cost of the perovskite cell is considered; on the basis of parameterssuch as photovoltaic construction cost, operation and maintenance cost, financial cost, depreciation cost and annual effective generating capacity; a PMT (Payment) function and an NPV (Net Pretent Value) function are utilized to calculate the power cost per kilowatt hour, and a detailed, reasonable and accurate calculation method is provided for the calculation of the power generation cost of theperovskite solar cell.

Description

technical field [0001] The invention relates to the field of solar photovoltaic power generation, in particular to a method for calculating the power generation cost of a perovskite solar cell. Background technique [0002] Since the first silicon solar cell came out in 1954, the application of photovoltaic power generation has become increasingly mature. As one of the third-generation solar cells, perovskite solar cells have benefited from many advantages such as bipolarity of perovskite materials, long carrier life, adjustable band gap, and wide light absorption range. Over time, a leap in efficiency has been achieved, from the initial 3.8% to the current 25.2%, which is close to the highest efficiency of silicon solar cells. Perovskite solar cells were selected by "Science" as one of the top ten scientific breakthroughs in 2013. It shows its excellent performance and bright future. [0003] Compared with silicon solar cells, the preparation method of perovskite solar ce...

This formula does not take into account the residual value of the system, and simply discounts the annual investment expenditure and annual power generation to the first year, and only obtains the cost discounted to a single specified moment, while ignoring the need for electricity sales revenue in the lifetime The fact that the monthly (or annual) recovery during the period creates a mismatch between costs and benefits, resulting in less accurate calculations
