Solar Energy 2
Presentation Dialogue
SOLAR ENERGY. All life on Earth depends on energy from the sun. Solar
energy is the source of energy for photosynthesis. It provides the warmth
necessary for plants and animals to survive. The heat from the sun causes
water on the Earth's surface to evaporate and form clouds that eventually
provide fresh rainwater.
Solar energy is the result of thermonuclear fusion reactions deep
within the sun. These reactions produce so much energy that …showed first 75 words of 2605 total…

across the junction, the field and the nature of the semiconductor material
discourage it from recrossing. A proportion of carriers which cross this
junction can be harvested by completing a circuit from a grid on the cell's
surface to a collector on the backplane. In the cell, the light pumps"
electrons out one side of the cell, through the circuit, and back to the
other side, energizing any electrical devices found along the way.
