Introduction to electromagnetic solar container ppt

What is solar energy?

This document discusses solar energy, defining it as energy derived from the sun, emphasizing its necessity due to the depletion of fossil fuels and their harmful environmental impacts. It outlines various types of solar technologies, including passive solar gain, solar thermal, concentrated solar power, and photovoltaic systems.

How does a solar concentrator work?

The oil heats up to around 400C, hot enough to heat water and make high pressure steam that can drive a turbine and generate electricity. Solar concentrators only work in direct sunshine. The mirror is held on a support that can turn to follow the sun as it moves throughout the day, adding to complexity and cost.

What are the four fundamental interactions of electromagnetic forces?

The electromagnetic force usually exhibits electromagnetic fields such as electric fields, magnetic fields, and light, and is one of the four fundamental interactions (commonly called forces) in nature. The other three fundamental interactions are the strong interaction, the weak interaction, and gravitation.

How are solar cells made?

Modern solar cells are created by junctions between different semiconductor materials. A typical crystalline silicon solar cell is a junction between boron-doped silicon (P-type) and phosphorus-doped silicon (N-type) semiconductors. N-type semiconductors are materials having excess electron charge carriers.

What is electromagnetism in physics?

Electromagnetism is a branch of physics involving the study of the electromagnetic force, a type of physical interaction that occurs between electrically charged particles.

What is a solar cell and how does it work?

A solar cell converts solar radiation to DC electricity and is the basic building block of PV modules and arrays. Modern solar cells are created by junctions between different semiconductor materials. A typical crystalline silicon solar cell is a junction between boron-doped silicon (P-type) and phosphorus-doped silicon (N-type) semiconductors.
