In an frightening line of research on solar cells, scientists are examining the connection between melanin (skin pigmentation) and solar cell development. Of course, it’s all clouded in jargon and officialese, but the basic idea is this: the creation of a melanin-based solar cell. This means that the skin of African-Americans and black fetuses could be used as an element in solar cells. (Source)

According to a research paper:
we suggest that a class of biological macromolecules called the melanins may be suitable replacements for the ruthenium complexes. They have strong, broad band absorption,  are chemically and photochemically very stable, can be cheaply and easily synthesized, and are also bio-available and bio-compatible. We demonstrate a melanin-based regenerative solar cell, and discuss the key properties that are necessary for an effective a-tfab-the-story-of-the-blonde-hair-blue-eyed-white-boy-master-master-color-textbroad band photon harvesting system.

The scientists note further that they are exploring the possibilities of using bio-organic pigments (melanin) to…explore the possibilities of using bio-organic pigments with broad band light absorbing properties as the primary photon harvesting component. In this context, we will concentrate on a class of bio-macromolecules called the melanins, and will also highlight several other potential material. What will hopefully become clear during this discussion, is the need to understand the detailed photophysical and photochemical properties of these molecules, and how these properties relate to their chemical and electronic structure.
