1.1.1 Introduction to Si-Based Fabrication Technology

Оглавление

Photovoltaics technology is a green method of energy production which is based on fabrication and manufacturing of solar cells on platform of Si wafers [9]. In this regard, it is mandatory to know about the Si wafers. So the silicon and its geometry as an integral component of the solar cell technology will be discussed first.


Figure 1.1 The above schematic shows the sun-earth geometry portraying distance between the two celestial objects, diameters and the value of solar constant.


Figure 1.2 The above figure portrays different radiations occurring from the sun which consists of direct, diffuse and reflected radiations.
