Question
Which of the following solar cell materials has maximum efficiency ?
The correct answer is
Ga As, single crystal
Solar Cell Material Efficiency Comparison
Solar cell efficiency measures the percentage of solar energy converted into electricity. Different semiconductor materials have distinct properties affecting their conversion efficiency.Comparing Material Efficiencies
The efficiency potential varies significantly among solar cell materials. Here's a comparison based on typical maximum efficiencies achieved:| Material Type | Specific Material | Typical Max Efficiency (%) |
|---|---|---|
| Thin Film | CdTe | Approximately 20% |
| Crystalline Silicon | Polycrystalline Si | Approximately 22% |
| Amorphous Film | Amorphous Si:Ge:H | Less than 10% |
| Single Crystal | GaAs (Gallium Arsenide) | Greater than 29% (Lab record) |
Material with Maximum Efficiency
Single crystal Gallium Arsenide (GaAs) demonstrates the highest solar energy conversion efficiency among the options provided. Its superior semiconductor properties enable more effective light absorption and charge carrier generation compared to silicon or thin-film alternatives like CdTe and amorphous Si:Ge:H. This makes GaAs the top performer for maximum efficiency in solar cells.Was this answer helpful?
