Abstract
The paper introduces a brief review on solar cells and different techniques that have been used to increase the efficiency. The discussion is then directed towards the current and cutting edge challenges on the issues related to fabrication and the increase in the solar cell efficiency. Primary focus is on the use of nanostructures in the context of solar cell fabrication and performance. The paper specifically informs on the use of techniques which focus on light absorption and trapping . One such technique which is reported in the paper is the fabrication of transparent
