During the photoelectric effect, that forms the basis of photovoltaic solar cells, a beam of monochromatic light consisting of an unknown number of photons knock electrons out of a metal producing an electrical current. For this effect, which statement is always true? The kinetic energy of each electron depends on the intensity of the light beam. The kinetic energy of each electron depends on the number of photons in the light beam. The kinetic energy of each electron depends on...

Question 2 simple solar cell uses what is called a photovoltaic effect in a semiconductor to create charges that can do work. Using what you know about what semiconductors look like in visible light, explain what you think the "photovoltaic "effect is and why are semiconductors used rather than insulators or metals?

Consider the following configuration of solar photovoltaic arrays consisting of crystalline silicon solar cells 1H2 There are two subsystems connected in parallel, each one containing two cells. In order for the system to function, at least one of the two parallel subsystems must work Within each subsystem, the two cells are connected in series, so a subsystem will work only If all cells in the subsystem work. Consider a particular lifetime value to, and we want to determine the probability...

It is planned to generate all energy needed by humanity from horizontal solar photovoltaic arrays with a 20 % efficiency. If 1% of the total land area of the earth is to be used for solar panels, what is the maximum population that this energy system can support? Assume that the world average per capita energy use is the same as at present.
