A novel approach to increasing light absorption in thin‐film solar cells is demonstrated by Jonathan Grandidier and co‐workers on p. 1272 . This new method involves redirecting the incident sunlight into the cell via coupling to the whispering gallery modes of dielectric spheres, which lie atop the cell. Such a scheme leads to a predicted current enhancement of >12% for a‐Si.
