Solar cells are given antireflection coatings to maximize their efficiency. Consider a silicon solar cell (n=3.50) coated with a layer of silicon dioxide (n=1.45). What is the minimum coating thickness that will minimize the reflection at the wavelength of 700 nm where solar cells are most efficient? answer is 121 nm.

Describe the working principle of a Silicon Solar Cell. a) How the solar cell generates electricity? Describe n/p doping, depletion region concepts. b) Describe the meaning of Fill Factor. How do you calculate the fill factor? What can be the reasons of bad fill factor behavior? c) A solar panel has an area of 0.5 m2 and illuminated with an irradiation of 1000W/m2 . Its open circuit voltage is 24 V and Short Circuit Current is 5.5 A. If the...

Solar electricity cost. Despite all the advantages of using solar cells to harvest solar energy, solar electricity still has an insignificant share (~1%) in the world’s overall energy supply picture. This is mostly due to the economic consideration. While there’s virtually no fuel (sunlight) cost and maintenance cost once the solar panels are installed, the initial cost of solar electricity systems is still the obstacle for wide-spread adoption of solar photovoltaic technologies. a. Use the single-crystalline Si solar panels as...
