Photosynthesis and Semiconductor-Based Solar Cells Photosynthesis‚ by definition‚ is “the process by which green plants and certain other organisms transform light energy into chemical energy” (photosynthesis‚ 2011). This is a remarkable process that occurs naturally and is one that is required for all living organisms to sustain existence on this planet. The efficiency of this process has sparked inventions‚ such as the semiconductor-based solar cell‚ that would allow humans to produce energy
