Can solar cells work at high temperatures?
If future missions designed to probe environments close to the Sun will be able to use photovoltaic power generation, solar cells that can function at high temperatures under high light intensity and high radiation conditions must be developed. The sig-nificant problem is that solar cells lose performance at high temperatures.
How does temperature affect the performance of solar cells?
At the temperatures and pressures of the surface, stability against chemical attack is a significant concern. These factors combine to multiply the challenges of power on the surface. The low light intensity alone reduces power availability, and the reduction of performance of solar cells due to temperature exacerbates this difficulty.
Should a high-bandgap solar cell be used for high-temperature operation?
For high-temperature operation, as discussed before, a high-bandgap solar cell ma-terial would be preferred, but the blue-deficient spectrum puts a limit on the availability of short-wavelength photons.
Why do solar arrays need a high temperature range?
Extending the temperature range of operation for solar arrays is highly desirable for extending the range of operation of space missions to the near-Sun environment [5e7]; interestingly, high temperatures help prevent arcing of solar arrays .
Why is Venus a challenging environment when considering solar power?
Four effects make the surface of Venus a challenging environment when considering solar power : corrosive environment The greatest difficulty is the surface temperature of Venus, averaging 452 C, with little difference between daytime and nighttime.
How does a thick atmosphere affect sunlight?
The thick atmosphere also filters the sunlight, with the surface solar spectrum depleted in blue wavelengths due to Rayleigh scattering. The surface pressure is 92 bars, equivalent to pressure a kilometer under the ocean, and the atmosphere is primarily of carbon dioxide.
