A Catalyst article looking at the use of plant cells to generate electricity via photosynthesis. This branch of science is called biophotovoltaics. The Sun is the ultimate source of energy for almost all life on Earth and harnessing this energy is one of the great scientific and technological challenges. Traditional fossil fuels are considered to be the main contributor to the greenhouse effect; they are subject to a large political risk and destined to run out. Conversely, solar energy is virtually carbon-free, extremely abundant and available worldwide. The article looks at this particular branch of natural power.

This article is from Catalyst: Secondary Science Review 2011, Volume 21, Issue 4.
