Question

Scientists have discovered that certain materials can convert light into electricity. What is one example of technology resulting from the application of this science knowledge

Answer 1

Solar panels

Step-by-step explanation:

The technology being described is the photoelectric effect. When a metal is illuminated by light having energy greater than the work function of the metal, electrons are ejected. In this way, light is converted in to electricity.

Solar panels are placed on the roof tops where there is no hindrance to solar energy. The solar panels have photo-voltaic cells which are sensitive to solar energy and convert it to electricity which is used to illuminate many households etc. specially in remote areas.

Answer 2

Answer: Photo-voltaic Cells

Step-by-step explanation:

The phenomenon of converting light into electricity is known as photoelectric effect, which consists of the emission of electrons (electric current) when light falls on a metal surface under certain conditions.

In this sense, the best known example of the application of this effect in technology is the implementation of photo-voltaic cells using the light energy of the Sun as a source of renewable energy. This process is also known as solar power, in which a system composed of photo-voltaic cells, lenses or mirrors and tracking systems are used to focus the sunlight into a small beam by the photoelectric effect with the help of semiconducting materials.

This type of installations may be built on ground, on a roof, or a wall, among other options; making it a good choice for the environment.
