Implications of light management in single- and multi-junction solar cells (Conference Presentation)
Author(s): Sarah R. Kurtz

Paper Abstract

Light trapping in solar cells has been studied for decades, but study of light rejection has been much less studied. Here, we discuss the benefits of rejecting sub band gap light and the broader tradeoffs of strategies for light management in tandem solar cells. Rejection of sub band gap light can lead to reduced operating temperature, with associated benefits of higher efficiency performance. Recycling of emitted light is known to increase the photovoltage relatively more than the photocurrent. Applying these light management techniques to tandem cells is more complicated, encountering the tradeoff between “recycling” the photons within the same sub-cell versus passing them to a lower sub-cell. The talk will give an overview of implications of light management techniques (excluding light trapping) in solar cells.
