6.1 Introduction

One of the most essential issues for human society in this century is the increasing demand for low cost, clean, and abundant sources of energy with nominal impact to the environment. In fact, solar energy with its limitless quantity is projected to offer a source of cleaner and low cost renewable energy. The solar power reaching the earth’s surface is equivalent to that provided by 130 million power plants of 500 MW [16]. However, the use of solar energy in the future as a main source depends on the success of vital factors of fundamental and technological concern. The devices used for solar energy conversion and for storage and distribution of solar energy must be friendly to the environment. Devices with lower production cost and great efficiency are, therefore, a requirement for light capture and solar energy conversion. The solar cell is an auspicious renewable energy storage device that converts solar energy into electrical energy; it is a major prospect to provide a solution to the upcoming energy related issues that humanity faces [79]. Currently, solar energy based technology is attaining great acceptance due to its several benefits, which comprise its proficiency to function with noiselessly and without toxicity or greenhouse gas release.
