consult the plot of efficiency of solar cells prepared by the National Renewable Energy Laboratory (NREL). As of 2010, the ______________ cell has the highest efficiency and _____________ cells have the lowest efficiency. (Fill in the blanks.)

Select one:

a. single crystal Si; dye-sensitized

b. two-junction concentrator; inorganic;

c. three-junction concentrator; organic

d. single-junction concentrator; amorphous Si:H

Expert Solution

From the Chart available for efficiency of solar cells at NREL as given in the question, we see that for 2010, the highest efficiency cell is of the type of Spire semicon which is marked as a three junction concentrator; organic. The single crystal cells lie in the mid region of the efficiency charts and the lowest efficiency is NREL (Zno/Pbs-QD) which is a two junction concentrator; inorganic type.

So,

Blank1- three junction concentrator; organic----------------(c)

Blank2- two junction concentrator; inorganic -------------------------(b)

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...

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.

The Florida Energy Factor (FEF) is used to compare the efficiency of domestic solar hot water heaters and to determine certain building construction credits. Solar water heaters with a high FEF are more cost efficient. Assume normality for the FEF distribution. A random sample of approved heaters was obtained, and the FEF value for each is given in the following: 3.3 3.2 1.8 2.1 4.2 3.9 4.6 6.3 1.9 1.9 4.9 6.7 5.2 3.1 1.4 Is there any evidence to...
