Across billions of years of evolution, Nature has retained a common light-absorbing hexameric cofactor core for carrying out the very first chemical reaction of photosynthesis, the light-induced electron transfer across approximately 3 nm. This process has direct analogies to light-driven charge separation in photovoltaic devices.

Read more'Organic and large-area electronics' (OLAE) is focused on materials and devices built from organic carbon-based molecules that are able to conduct electricity. Because these are lighter, more flexible and less expensive than inorganic conductors, such as copper or silicon, they are a viable alternative for many electronics applications.
