With the fast growing demand in off-grid applications in areas extending from villages to hills, newer technologies will have to be MADE IN INDIA. We will start with the basics of energy sources ranging from thermal, mechanical, and photovoltaic sources. The lectures will cover the topics on electricity generation using solar cells, use of solar heaters, solar based mobile chargers and the use of solar cookers in India. Subsequently, we will shift our attention to wind, water, tidal and geothermal power. At the end, the need for efficient energy storage technologies will be discussed. These include Li batteries and supercapacitors. The additional required concepts such as free electron model, p-n junction, coriolis force, turbulence, standing waves, thermodynamics, capacitors, crystal structure, etc. will also be discussed.The basics of various characterization techniques useful for evaluating energy systems will also be explained. These include cyclic voltammetry, charge discharge, EIS, quantum efficiency, etc. will be explained. (from nptel.ac.in)
