The Development of Solar Cells Technology

Abstract

Solar Energy is becoming a very recognized and reliable alternative source. The challenge is the very high cost of fabrication so; many studies were done in the field as a result there is new direction in this aspect. It is material science and Nano technology. The fabrication using such technique is cheap to some extent, and flexible; for instances "spray" on walls of the cell, printing on papers or even developing very thin nanoparticles of silicon, and colloidal quantum dots; within mind of course improving the efficiency to the maximum range.
