If you cant see it , the maximum power output of this solar cell is 0.52W. When the light intensity is 450W/m^2 the cell has an efficiency of 0.15 at the maximum power output. Calculate the area of the solar cell

If the output is 0.52 W, then 0.52 is 15% of the input power. Calculate the input power.

Then, knowing that 450W is what you get for each sq metre of cell, you should be able to find the area of the cell by ratio and proportion
