Students will be exposed to a broad brush of topics related to energy and environment with a focus on a societal problem of great current concern—namely, the use of energy and the local, regional, and global environmental effects that use engenders. Students will become familiar with the modern technology being used to ameliorate these adverse environmental effects. It enables the student to integrate this understanding into an appreciation of both the technology and science that must be employed by nations to maintain a livable environment while providing improved economic circumstances for their populations. In our life of every day, we see these forms. For examples a rechargeable battery stores readily convertible chemical energy to operate a mobile phone. Even food(which is made by the same process as fossil fuels) is a form of energy stored in chemical form.Energy storage is a dominant factor in economic development of our country and life. The main target of the present course is to assess and understand the process behind the most important (and well known) forms of storing energy. We will focus on solar cells as devices for storing solar energy in order to understand their functioning mode for photovoltaic applications.
