Why bioelectrodes for energy conversion are not stable

Source: Science Daily

Researchers have discovered why bioelectrodes containing the photosynthesis protein complex photosystem I are not stable in the long term. Such electrodes could be useful for converting light energy into chemical energy in an environmentally friendly way. However, the proteins, which are stable in nature, are not functional in semi-artificial systems in the long term because reactive molecules are formed that damage the photosystem I.
