Best Research cell efficiencies

How efficient are photovoltaic technologies?

As with any energy conversion process, there is a physical limit for the photovoltaic conversion process.

Solar Thermal Plant

What are the different kinds of solar electricity generation technologies?

There are many different technologies to generate electricity from solar energy.


Could solar really meet most of the world's energy needs?

Today, solar energy provides less than one percent of the world's energy, but that share could grow considerably with the right public policies and continued price reductions.

solar panel

What’s the difference between solar power and solar energy?

Solar energy is broadly defined as the total energy that the sun radiates through visible light and other unseen electromagnetic waves.


What is Passive Solar Heating?

Passive solar heating, also known as passive solar design, takes advantage of a building’s architectural design to store and distribute solar energy in the form of heat.

Organic Cells

What are organic solar cells?

An organic solar cell uses organic electronic materials to convert sunlight to electricity through the photovoltaic effect.


What are perovskite cells?

Perovskite (calcium titanate) cells are a particularly promising new solar technology.

Quantum Dot Cells

What are quantum dot cells?

Quantum dots are tiny crystals of semiconductor material, roughly 2-10 nanometers, containing only hundreds to thousands of atoms.

Solar Tech thermal

What types of solar thermal electric technologies exist today?

Concentrated solar power (CSP) technologies convert sunlight to heat energy. Much like conventional power plants, CSP technologies then use heat energy to generate electricity.

Solar Technologies

What types of solar photovoltaic technologies exist today and how do they work?

Photovoltaic (PV) systems directly convert sunlight into electricity. The PV effect is the process from which light (photons) is converted into electric current.

Solar Heaters

How do solar air and water heaters work?

Both solar air and solar water heaters convert sunlight to heat, and both can be divided into active systems, which operate with the help of pumps or fans, or passive systems, which do not.
