In order to not be as heavily influenced by dark current and give a more accurate snapshot of the device under its intended working conditions,. Once you've gotten responsivity through the test described above, the EQE is really easy to calculate. We've already seen the equation that allows us to do this: Where h is Planck's constant, c is. It turns out that, using the method described above for measuring responsivity, we also get enough information to calculate the total current out of the device. Because there is a great deal of work both commercial and academic in the field of photovoltaics, there is also a great need for standardization of the methods and means of comparing one. If we rearrange the efficiency equation from earlier, we see that we can calculate the efficiency as soon as we know the maximum power point, and the incident power: One thing to be.
