How do solar panel works?
How Do Solar Panels Work ? When photons hit a solar cell, they knock electrons loose from their atoms. When electrons flow through such a circuit, they generate electricity. Multiple cells make up a solar panel , and multiple panels ( modules ) can be wired together to form a solar array .
When the source of light is not sunlight then the photovoltaic cell is used as?
Explanation: When the source of light is not the sun light then the photo voltaic cell is used as the photo detector. The example of the photo detector is the infra-red detectors.
What is another example of nanotechnology?
Examples include titanium dioxide and in sunscreen, cosmetics and some food products; silver nano-particles in food packaging, clothing, disinfectants and household appliances such as Silver Nano; carbon nano-tubes for stain-resistant textiles; and cerium oxide as a fuel catalyst.
What is nanotechnology in medicine?
Share Article. Nanomedicine refers to the area of science that combines nanotechnology with drugs or diagnostic molecules to improve the ability to target specific cells or tissues. These materials are produced on a nanoscale level and are safe to introduce into the body.
What are the advantages of solar cell?
Advantages of Solar Energy Renewable Energy Source . Among all the benefits of solar panels, the most important thing is that solar energy is a truly renewable energy source . Reduces Electricity Bills. Diverse Applications. Low Maintenance Costs . Technology Development.
What is the basic principle of solar cell?
Silicon crystals are laminated into n-type and p-type layers, stacked on top of each other. Light striking the crystals induces the “ photovoltaic effect,” which generates electricity. The electricity produced is called direct current (DC) and can be used immediately or stored in a battery .
What is the function of solar cell?
Solar cell, also called photovoltaic cell, any device that directly converts the energy of light into electrical energy through the photovoltaic effect.
