Insects and diseases might cause such symptoms, but it may actually be sunscald. Bell peppers are susceptible to sunscald, which occurs during high temperatures, especially during humid conditions, and direct exposure of the fruit to sunlight during its development. It can appear as faded, papery, blistered, or gray-white sunken areas on the fruit on the side that has been exposed to the sun; the areas will later dry and possibly develop black mold. It is best to have the fruit develop under the leaves; you can provide shade cloth or use row covers to help protect them. Staking plants as they grow also helps fruit to remain under the leaf canopy. Good watering and fertilization at the appropriate times help to develop a good canopy. Hope this helps!
