Light refracting cells!

Clams have a symbiotic relationship with photosynthetic algae. This algae lives within the fleshy mantle of clams, growing into pillar like formations. In order to expose this helpful algae to just the right amount and kind of sunlight, clams have developed a special cell called iridocytes that refract the sunlight and split it up so that only the types of light that the algae photosynthesizes best, red and blue light, gets through! Because the iridocytes reflect green and yellow light, it causes the clams to have an iridescent glow. There are studies on these cells that are looking into ways to utilize these cells so that we can farm algae in layered pads to produce biofuels! Some questions I have about this would be how much energy would the biofuels from the algae produce? Would we be able to use these biofuels in conjunction with solar panels to replace fossil fuels all together?
