A solar cell (also called photovoltaic cell or photoelectric cell) is a solid state electrical device that converts the energy of light directly into electricity by the photovoltaic effect. Assemblies of cells used to make solar modules which are used to capture energy from sunlight‚ are known as solar panels. The energy generated from these solar modules‚ referred to as solar power‚ is an example of solar energy. Photovoltaics is the field of technology and research related to the practical

Henrietta’s Cells. It is unfortunate that the Lacks family did not know that research was being done on Henrietta’s cells‚ which made the family feel like they were betrayed by doctors at the Johns Hopkins Hospital‚ but it was a common practice of doctors in the 1950s and consent was not required for research as it is today. Also‚ it is unfair that Samuel Reader and Monroe Vincent‚ the founders of Microbiological associates‚ a cell distribution company‚ made millions off of selling HeLa cells. However
