A diode is a semiconductor device that allows current to flow in only one direction. Although there may be several reasons why there is a diode on a calculator PC board, a common reason would be to protect the device from a battery inserted in the wrong direction (if battery powered) or if an AC adapter is used, to make AC into DC current.

What is the difference between p n junction and zener diode?

The difference between the pn-junction diode and the zener diode is that the pn-junction diode is used for rectification while the zener diode is used for rectification and stabilization. Also, the zener diode can function in the breakdown region while the pn-juntion diode can not function in that regime.
