In many applications the intensity of the light, be it visible, infrared, or a combination of the two, is very low. Most applications need a high ratio of signal to noise, the higher the better. If the intensity can't be increased, the area of the photodiode becomes a critical factor. The larger the area, the greater the output current or signal. In wearable applications, for example, the amount of light reflecting off the skin layers can be very low, so large area photodiodes are key.
