Fill factor in organic solar cells
The fill factor (FF) is an important parameter that determines the power conversion efficiency of an organic solar cell. There are several factors that can significantly influence FF, and these factors interact with each other very intricately. Due to this reason, a deep understanding of FF is quite difficul
Solar Cell Voltage: Understanding The Basics
Tandem solar cells are a type of solar cell that uses two or more semiconductors with different bandgaps to increase the overall efficiency of the solar cell. This is achieved by stacking the semiconductors on top of each other, with the highest bandgap material on top and the lowest bandgap material on the bottom.
