Limit of light coupling strength in solar cells
A. Naqavi, F. -J. Haug, C. Ballif +2
We introduce a limit for the strength of coupling light into the modes of solar cells. This limit depends on both a cell's thickness and its modal properties. For a cell with refra…
Angular behavior of the absorption limit in thin film silicon solar cells
Ali Naqavi, Franz-Josef Haug, Karin Söderström +5
We investigate the angular behavior of the upper bound of absorption provided by the guided modes in thin film solar cells. We show that the 4n^2 limit can be potentially exceeded…
Light trapping in solar cells at the extreme coupling limit
Ali Naqavi, Franz-Josef Haug, Corsin Battaglia +2
We calculate the maximal absorption enhancement obtainable by guided mode excitation in a weakly absorbing dielectric slab over wide wavelength ranges. The slab mimics thin film si…
