Which of the following is an improvement in the new field of thermophotovoltaics for converting solar energy?
  1. Allows significant increases in the proportion of solar input that can be converted into energy
  2. Creates a means for incorporating geothermal sources into solar conversion where feasible
  3. Provides a more consistent power source than does regular photovoltaic conversion
  4. DBoth A and C above
  5. .
Explanation
Answer: D - Thermophotovoltaics shows great promise as a technology for busting through the perceived ceiling of solar cell conversion performance by using more of the sun’s spectrum than photovoltaics can use. In addition, implementation of thermophotovoltaics facilitates a more consistent power stream than that from existing photovoltaic technologies, thus addressing one of the most often-expressed concerns about the limitations of solar energy.
