## Homework Statement

Hi!

I have a problem with the following problem:

__Calculate the efficiency of the solar cells with the characteristics given in the table below__Power (28 degrees, BOL): 300 W/m2 Absorptance: <91 , emittance: >82. Reliability: 0.999 . Mass: 2 kg

## Homework Equations

I know that the equation for efficiency calculations is:

(maximum eficiency) = (maximum power output)/ (incident radiation flux * Area of the array)

But I don't know what to do since the absorptance and emittance is included. Please, help me :/

## The Attempt at a Solution

I assumed that the area is I m2. The power output is given above.

I divided the emittance with absorptance ...And now I'm stuck
