ABSTRACT
Silicon is well studied and abundantly available material for making CMOS integrated circuit and high power electronic devices. When a normal and simple p-n junction diode is shined with s spectrum of light in the vicinity of its junction, electron-hole pairs are generated and they are accelerated by the built-in electric field to produce the electromotive force between its terminals. This is known as photovoltaic effect. The conventional efficiency of a p-n junction solar cell mainly limited by reflection of part of shined light due to Fresnel reflection. However, its reflection itself may be utilized to increase total absorption light by a p-n junction solar cell, if we texture the surface in such a way that multiple reflection and hence improved absorption of light occur between the facets on its surface. This paper focuses mainly on the studies made by researchers to achieve a textured surface thereby increasing the possibilities of improved efficiency.
