Current is minimise in reverse biasing

Yogita Ingle 7 years ago

The current in the forward bias is primarily due to major carriers but in reverse bias it is due to the minor carriers. As the fractional change in the reverse current due to the photoeffects is more easily measurable than in the forward bias current. So photodiodes are operated in the reverse bias.
