4 FAQs about Solar power generation equipment materials

What materials are used in solar cells?

The materials used in solar cells have evolved significantly, with current technologies incorporating silicon, gallium arsenide (GaAs), perovskites, and organic materials. Silicon-based solar cells dominate the market due to their efficiency and durability, while GaAs cells offer high efficiency and resilience, particularly in space applications.

What are the different types of solar PV technologies?

We broke down the conventional solar PV category into crystalline silicon PV as well as three thin-film solar technologies: Cu In Ga diselenide (CIGS), Cd telluride (CdTe), and amorphous silicon germanium (aSiGe). Our primary study boundary for material requirements is limited to generation and transformer infrastructure only.

What equipment do I need to go solar?

You need solar panels, inverters, racking equipment, and performance monitoring equipment to go solar. You also might want an energy storage system (aka solar battery), especially if you live in an area that doesn't have net metering.

Which raw materials are used in electricity generation technologies?

The remaining materials (Ag, Cd, Dy, Ga, In, Mn, Nd, Ni, Se, and Te) we designate as “specialty metals.” This is not an exhaustive list of raw materials used in electricity generation technologies.
