Photosynthetic efficiency

The photosynthetic efficiency is the fraction of light energy converted into other forms of energy for use. Trees convert light in to chemical energy through the process of photosynthesis with a photosynthetic efficiency of approximately 0.2-0.5%. Other numbers reported range up to 6%, a more detailed analysis is required. By comparison solar panels convert light into electric energy at a photosynthetic efficiency of approximately 10-20%. The photosynthetic efficiency varies with the frequency of the light being converted.
