What are Gallium-doped Solar Panels?

Gallium-doped Solar Panels use Gallium-doped silicon (GaAs) as an effective alternative to boron-doped silicon for photovoltaics due to its stability in light, relatively high band gap, and low cost. GaAs are typically prepared by a sol-gel method. However, the quality of the final product can vary depending on the conditions used to prepare it. The band gap of GaAs is relatively high, so it is not as efficient at converting solar energy into electricity as other semiconductors. However, this can be improved by using a thin layer of gold to increase the absorption coefficient.

What are the advantages and disadvantages of Gallium doped Solar Panels?


  • 1-Low PID: Gallium-doped Solar Panels tend to have lower rates of PID which makes them in the top tier for long-life solar panels without losing that much power output percentage.
  • 2-Temperature: Gallium-doped Solar Panels can work at much higher temperatures than other traditional types making them very suitable for applications in areas that have high temperatures.
  • 3-Cost: Gallium-doped Solar Panels have a cheaper cost to manufacture than traditional solar panels making them very competitive in the solar panel market.


  • 1- Efficiency: Gallium-doped Solar Panels tend to have lower efficiencies than other types of solar panels which is a major drawback for a lot of applications that require high-efficiency solar panels.
  • 2- Durability: Gallium-doped Solar Panels’ durability is not that good due to the solar cell instability making scientists & researchers still believe it was so early to be introduced to the market.

What are the use cases of Gallium doped Solar Panels?

  • 1-Deserts Plants: Gallium-doped Solar Panels are really good to be used in hot deserts as they work in higher temperatures which is a big advantage for such areas that have temperatures that can reach 50℃.
  • 2- Small electronics: Gallium-doped Solar Panels can be used in small electronics products as they tend to have low PID which can make them stay longer with less power output loss year by year making such solar panels suitable for such applications than other types of solar panels currently in the market.
