Abstract

The invention relates to a solar cell (100) having a light trap. One embodiment of the solar cell (100) comprises a photovoltaic element (101) having a front side (102) and an opposite rear side (103). A holographic element (104) is disposed on the front side of the photovoltaic element (101), wherein it allows at least part of the incident light (105) to pass and thus deflects said light into the photovoltaic element (101), without thereby concentrating said light, so that said light experiences an increase in optical path length between the front side (102) and rear side (103).
