Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the system.
The efficiency of a solar cell (sometimes known as the power conversion efficiency, or PCE, and also often abbreviated η) represents the ratio where the output electrical power at the maximum power point on the IV curve is divided by the incident light power – typically using a standard AM1.5G simulated solar spectrum.
In addition to reflecting the performance of the solar cell itself, the efficiency depends on the spectrum and intensity of the incident sunlight and the temperature of the solar cell. Therefore, conditions under which efficiency is measured must be carefully controlled in order to compare the performance of one device to another.
High-performance solar plants can reach a performance ratio of up to 80%. Learning all this is important to know how to calculate the PV performance ratio. What is the Purpose of the Performance Ratio? The performance ratio helps assess the energy efficiency and reliability of a solar power plant.
Select a minimum analysis period of 1 month to mitigate the influence of factors like low solar elevations, low temperatures, and shadows on the calculation. 4. Manual calculation of the performance ratio (PR): Use the following simplified formula: PR = Actual reading of plant output in kWh p.a. /Calculated, nominal plant output in kWh p.a.
At the maximum efficiency, the top cell absorbs 501.36 W/m 2 from the total 1,000.37 W/m 2 of sunlight power. Therefore, the incoming power is almost equally shared between the two cells; however, the top cell loses 43.3% of its incoming power while the Si bottom cell misses 71.2% of the sunlight power that enters into it.
