This course will be introduce you to solar energy, the uses of solar energy, the concept of solar radiation, the different matrices to quantify solar radiation, the fundamental aspects of solar radiation, the atmospheric effects on solar radiation, the effect of location on time, and identifying the basis of the Sun-Earth angular rotations.
You will also be introduced to various models of measuring solar radiation, various geometrical relations, sun-surface geometry for an inclined angle, the equation of time, how to calculate sunrise, sunset and day length with all the necessary adjustments, local apparent time, basic principles of semiconductors, structure of semi-conductor materials, and electrical properties of semiconductors.
Also, you will be introduced to the conductivity and resistivity of semi-conductors, the measurement of resistivity, the measurement of mobility, band diagram in semi-conductors, the concept of carrier diffusion, total current, the various forms of carrier generation and recombination, recombination-generation statistics, low-level injection methods and the conditions for low-level injection, surface recombination, photon absorption, momentum conservation, diffusion length, and direct and indirect (diffuse) bandgap semi-conductors.
