Why it is preferred to operate photodiodes in reverse bias?

Because in reverse bias it is easier to observe change in current with change in the light intensity

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.
