6 FAQs about [Principle of silicon-based solar power generation]

Why is silicon the dominant solar cell manufacturing material?

Provided by the Springer Nature SharedIt content-sharing initiative Policies and ethics Silicon (Si) is the dominant solar cell manufacturing material because it is the second most plentiful material on earth (28%), it provides material stability, and it has well-developed industrial production and solar cell fabrication technologies.

What is the operating principle of a solar cell?

Conceptually, the operating principle of a solar cell can be summarized as follows. Sunlight is absorbed in a material in which electrons can have two energy levels, one low and one high. When light is absorbed, electrons transit from the low-energy level to the high-energy level.

Why is silicon a good material for solar cells?

Silicon has a bandgap of approximately 1.12 eV, which is one of the reasons that makes it an excellent material for solar cells (Box 3.1). Why do we use silicon solar cells?

How efficient are silicon solar cells?

As one of the PV technologies with a long standing development history, the record efficiency of silicon solar cells at lab scale already exceeded 24% from about 20 years ago (Zhao et al., 1998).

How much electricity does a silicon solar cell use?

All silicon solar cells require extremely pure silicon. The manufacture of pure silicon is both expensive and energy intensive. The traditional method of production required 90 kWh of electricity for each kilogram of silicon. Newer methods have been able to reduce this to 15 kWh/kg.

What is the device structure of a silicon solar cell?

The device structure of a silicon solar cell is based on the concept of a p-n junction, for which dopant atoms such as phosphorus and boron are introduced into intrinsic silicon for preparing n- or p-type silicon, respectively. A simplified schematic cross-section of a commercial mono-crystalline silicon solar cell is shown in Fig. 2.
