Fill factor (FF) is an important measurement that you can use to evaluate the efficiency of solar cells. To calculate fill factor, you need to divide the maximum possible power output of a cell by its actual power output. This will give you a measurement that you can use to assess the performance of your solar cell. So
Photovoltaic cells operate by converting light energy, photons, into electrical charge, electrons. The efficieny of photovoltaic cells is defined to be the amount of work done per photon. Solar cells are able to achieve a maximum efficiency of 33%. In other words, a best case scenario cell would absorb 33% of the photons that the cell receives.
Two types of quantum efficiency of a solar cell are often considered: External quantum efficiency (EQE) is the ratio of the number of charge carriers collected by the solar cell to the number of photons of a given energy shining on the solar cell from outside (incident photons). Internal quantum efficiency (IQE) is the ratio of the number of charge carriers collected by the …
