Plant vs. Solar cell Professor Lynn Roginsky Introduction to Biology November 23, 2012 Photosynthesis is the process by which green plants and certain other organisms transform light energy into chemical energy. This is a remarkable process that occurs naturally and is one that is required for all living organisms to sustain existence on this planet. In order to create food, plants absorb sunlight and create oxygen. While this process takes place, plants use sunlight and carbon dioxide to convert water molecules into hydrogen, oxygen, and electrons I will compare and contrast the photosynthetic process with that of semiconductor-based solar cells in their abilities to produce energy. In order to discuss the photosynthesis and the semiconductor based solar cell, we need to understand what is involved in each process and how they could be different or the same. The primary comparison between photosynthesis and semiconductor-based solar cells is that they require solar energy, or sunlight, to begin the processes. In photosynthesis, plants use chlorophyll, often found in green leaves, to absorb solar energy from the sun. A photovoltaic (PV) panel provides sunlight to the solar cells. Similar to how sunlight helps produce chlorophyll in plants, semiconducting material absorbs sunlight. Photosynthesis and semiconductor solar cell both have cells that trap energy from the sun. The manner in which light is converted in both photosynthesis and a semiconductor-based solar cell is also very similar. The plants use solar energy from the sun, water absorbed in from the plant’s roots and carbon dioxide from the air to produce glucose, the chemical energy or food that the plants need to survive, and oxygen that is then released into the atmosphere. Lastly, both photosynthesis and semiconductor-based solar cells are more efficient when direct sunlight is
