Question

In silicon photovoltaic cells what does Silicon (n type) Silicon (p type) means ?

Answer 1

P type semiconductor
#doped by group 13 element
# 3 covalent bond formed
# electron and hole move in opposite direction
# electron deficit
N type semiconductor
#doped by group 15 element
# one electron extra unbounded
#conductivity due to negative charged electrons

• Photovoltaic cells generate electricity by absorbing sunlight and using that light energy to create an electrical current.
• When light shines on the cell it creates an electric field across the layers causing electricity to flow.
• Photovoltaic Cell are used to produce electricity which powers a water pump, well etc.
