Silicon solar cells vs. thin-film solar cells Compare
silicon solar cells with thin-film solar cells in the following
aspects: (1) device structure; (2) working principle; (3)
efficiency; and (4) cost. Need informative answer for my clear
understandings.
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...
Make a table that summarizes results over the last four years (2013-2017 only) in understanding degradation in amorphous silicon solar cells. The table should have two columns: (1) Brief description of the main results in the paper, and (2) Reference for the paper
