The advantage of the organic photoelectric conversion layer is twofold. It sits above the metal circuitry and transistors, which means that it can cover the entire area of the sensor without requiring a light-shielding film around the edges. This means it can take advantage of more light, which Fujifilm claims "boosts sensor sensitivity by 1.2 times". And since the film is much thinner than previous technology, it can sit closer to the top of the lens, allowing for a wider degree of incident light. This is said to allow for high color fidelity, and potentially allow for smaller lenses.
