Question

Solar cells generate a potential difference when exposed to sunlight. In an experiment, you wish to charge a rechargeable battery by connecting it in series to an array of solar cells. You perform the experiment outdoors, in direct sunlight, when the intensity of solar radiation is

1000 W/m2.

However, your solar cells only have an efficiency of 11% (that is, only 11% of the sunlight power transmitted to the solar cells is delivered to the rechargeable battery). While the circuit is connected, you measure at one instant the potential difference across the battery to be 4.55 V and the current in the circuit to be 0.23 A. What is the area of the array of solar cells? ****Please write out the answer so I can follow along with your math! I'm not just looking for the answer, I need help with the actual math part**** Thank you :)

Explanation / Answer

Power of battery =potential diffrence*current=4.55*0.23=1.0465 watt

11%is equivalent to 1.0465waat

100% isequivalet to 1.0465*100/11=9.51 watt

required area=9.51/1000 m2
