6 FAQs about [Photovoltaic basics i-v]

What are photovoltaic cells & how do they work?

Photovoltaic (PV) cells, or solar cells, are semiconductor devices that convert solar energy directly into DC electric energy. In the 1950s, PV cells were initially used for space applications to power satellites, but in the 1970s, they began also to be used for terrestrial applications.

What is a photovoltaic system?

The literal translation of the word photovoltaic is light-electricity—and this is exactly what photovoltaic materials and devices do—they convert light energy into electrical energy. PV systems generate power without pollution—and recent advancements have greatly improved their efficiency and electrical output.

Should you consider a photovoltaic (PV) system?

If you are thinking of generating your own electricity, you should consider a photovoltaic (PV) system—a way to gen-erate electricity by using energy from the sun.

What is a third type of photovoltaic technology?

A third type of photovoltaic technology is named after the elements that compose them. III-V solar cells are mainly constructed from elements in Group III—e.g., gallium and indium—and Group V—e.g., arsenic and antimony—of the periodic table. These solar cells are generally much more expensive to manufacture than other technologies.

How does light intensity affect a photovoltaic cell?

By the wavelength of the incident rays. Increasing light intensity will proportionally increase the rate of photo-electron emission in the photovoltaic material. In actual applications, the light absorbed by a PV cell will be a combination of direct solar radiation, as well as diffuse light bounced off of surrounding surfaces.

What are new photovoltaic technologies?

Solar cell researchers at NREL and elsewhere are also pursuing many new photovoltaic technologies—such as solar cells made from organic materials, quantum dots, and hybrid organic-inorganic materials (also known as perovskites). These next-generation technologies may offer lower costs, greater ease of manufacture, or other benefits.
