Why does a semiconductor have fewer electrons than a conductor?

Valence electrons only are able to cross the energy gap in semiconductors since it is greater than that of conductors. That is why semiconductors have fewer free electrons than conductors.

Which two statements describe the reasons a solar cell must contain semiconductors?

Semiconductors have properties that allow them to convert sunlight into electricity through the photovoltaic effect. The band gap in semiconductors enables them to absorb photons from sunlight and generate electron-hole pairs for creating an electric current.


What is the meaning of semiconductors?

Oversimplifying it significantly "not quite conductors". These are materials whose ability to conduct electricity is between conductors and insulators but can be very precisely controlled by doping with other elements as impurities, allowing the construction of electronic devices that can: control the direction of current flow, amplify signals, act as switches, perform boolean logic functions, etc. These materials can be classed as elemental semiconductors, binary semiconductors, other semiconductors. The elemental semiconductors are elements with 4 valence electrons that are not metals (e.g. silicon, germanium), the binary semiconductors are "alloys" of two elements: one with 3 valence electrons and the other with 5 valence electrons (e.g. gallium arsenide, indium phosphide), other semiconductors can be elements (e.g. selenium) compounds (e.g. galena, copper oxide) or complex "alloys" of several elements (e.g. gallium arsenide phosphide, aluminum gallium indium phosphide). The term semiconductors is also used to refer to the electronic devices mades of these materials.


What are the semiconductors in the periodic table?

Semiconductors can either be intrinsic or extrinsic. Intrinsic semiconductors are elements that are in their pure form. These will usually have positive and negative sides because the electrons migrate towards one direction. On the other hand, extrinsic semiconductors are when the conductivity (or ability to make an electric charge with the electrons) are controlled by adding other atoms. These atoms that are added are called dopants. Dopants donate or receive electrons from the semiconductor to make impure.


How are n-type and p-type semiconductors similar?

N-type semiconductor materials which have free electrons,(which are negatively charged).P-type semiconductor materials which have too few electrons. Therefore the opposite of electrons - holes (which are negatively charged).You can think of it like positive and negative poles of a magnet.
