Abstract
Provided is a solar cell including a condensing micro lens array. The solar cell includes a lower electrode, a photoactive layer including a top formed with an upper opaque metal grid electrode and a bottom end disposed on the lower electrode, the photoactive layer being formed of III-V compound semiconductors to absorb solar light to generate photo-electric conversion, and the micro lens array disposed to have a certain gap from the top of the photoactive layer and refracting incident solar light toward the photoactive layer.
