Peridinin-chlorophyll-protein complex the peridinin molecules to their neighboring chlorophyll molecule. PCP has served as a common model system for spectroscopy and for theoretical calculations relating to the protein's photophysics. PCP complexes are thought to occupy the thylakoid lumen. After energy transfer from the peridinin to the chlorophyll pigment, PCP complexes are believed to then transfer energy from the excited chlorophyll to membrane-bound light harvesting complexes. Peridinin-chlorophyll-protein complex The peridinin-chlorophyll-protein complex (PCP or PerCP) is a soluble molecular complex consisting of the peridinin-chlorophyll a-protein bound to peridinin, chlorophyll, and lipids. The peridinin molecules absorb light in the blue-green wavelengths (470 to 550 nm)
Artificial photosynthesis particular how much of the incident light can be used in a system in practice. This is comparable with photosynthetic efficiency, where light-to-chemical-energy conversion is measured. Photosynthetic organisms are able to collect about 50% of incident solar radiation, however the theoretical limit of photosynthetic efficiency is 4.6 and 6.0% for C3 and C4 plants respectively. In reality, the efficiency of photosynthesis is much lower and is usually below 1%, with some exceptions such as sugarcane in tropical climate. In contrast, the highest reported efficiency for artificial photosynthesis lab prototypes is 22.4%. However, plants are efficient in using CO at atmospheric
