Abstract (en)
[origin: WO2009146845A2] One embodiment of the invention discloses a solar cell (100) having a light trap (104). The solar cell (100) comprises a photovoltaic element (101) having a front side (102) and an opposite rear side (103). The 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).
