We studied the possibility of photocurrent enhancement in Dye Solar Cells (DSCs) by means of two strategies of light management, namely the use of a scattering layer (SL) and the efficient coupling of incoming light into the cell. The first leads to a significant enhancement in conversion efficiency, as evident from IV characteristics and Incident Photon-to-Current Efficiency (IPCE) measurements of cells provided with SL The latter was investigated by using angle resolved Attenuated Total Reflection (ATR) technique that evidenced a strong angular dependence of the photocurrent and further enhanced upon using a coupling prism. Both strategies are found to be based on the increase of the light path inside the active layer. (C) 2009 Elsevier Ltd. All rights reserved.

Abstract
We studied the possibility of photocurrent enhancement in Dye Solar Cells (DSCs) by means of two strategies of light management, namely the use of a scattering layer (SL) and the efficient coupling of incoming light into the cell. The first leads to a significant enhancement in conversion efficiency, as evident from IV characteristics and Incident Photon-to-Current Efficiency (IPCE) measurements of cells provided with SL The latter was investigated by using angle resolved Attenuated Total Reflection (ATR) technique that evidenced a strong angular dependence of the photocurrent and further enhanced upon using a coupling prism. Both strategies are found to be based on the increase of the light path inside the active layer. (C) 2009 Elsevier Ltd.
