Question

a dye-sensitized solar cell is tested under illumination and measures a maximum power output of 0.13 w. if the input power is equal to 1.9 w, what is the energy conversion efficiency of this solar cell?

Answer 1

The energy conversion efficiency of the dye-sensitized solar cell is calculated by dividing the maximum power output (0.13 W) by the input power (1.9 W) and multiplying by 100, resulting in approximately 6.842%.

Step-by-step explanation:

To calculate the energy conversion efficiency of a solar cell, you divide the maximum power output by the input power and then multiply by 100 to get a percentage. For a solar cell with a maximum power output of 0.13 W and an input power of 1.9 W, the calculation would be:

• Energy conversion efficiency = (Maximum power output / Input power) × 100%
• Energy conversion efficiency = (0.13 W / 1.9 W) × 100%
• Energy conversion efficiency = 0.06842 × 100%
• Energy conversion efficiency = 6.842%

So, the energy conversion efficiency of the dye-sensitized solar cell is approximately 6.842%.
