What material is used in some photovoltaic panels?AgoldBsiliconChydrogenDplatinum

Photovoltaic panels, commonly known as solar panels, primarily use silicon as the semiconductor material to convert sunlight into electricity. Silicon is favored for its excellent electrical properties and abundance. There are variations of silicon used in these panels, such as mono-crystalline, poly-crystalline, and amorphous silicon.

Here’s a brief overview of the options provided:

1. Gold - While gold can be used in some electronic components due to its excellent conductivity, it is not used as the primary material in photovoltaic panels.

2. Silicon - This is the correct answer. Silicon is the main material used in photovoltaic cells to absorb sunlight and generate electric current.

3. Hydrogen - Hydrogen is not used in photovoltaic panels. However, it plays a role in other energy storage technologies.

4. Platinum - Like gold, platinum is not a primary material in photovoltaic panels but may be used in certain applications for its catalytic properties.

Conclusion

Thus, the material used in some photovoltaic panels is B. silicon.
