Abstract:
Throughout history, human progress has been energy dependent. In the early stages of life, wood was used to cook food, to provide heat and later to melt metals, generally providing the main source of energy. The economic development and standard of living of communities is directly dependent on the useful forms of energy available. Electricity is such a useful form that it can be made from readily available energy sources and is used all over the world. The use of sunlight to generate electricity has been discussed for many years as an alternative source. As the sun rotates, the light falling on the Earth is constantly changing. So the question is how can we use sunlight most effectively? Scientists have tried different methods of using solar energy more efficiently. For example, active and passive solar tracking systems have been tried. These systems are still widely used today, but people are still looking for more efficient methods for solar energy efficiency. This spherical microcell is called Sphelar and this cell avoids the traditional photovoltaic design and uses a much more efficient shape. While traditional flat solar cells are easy to design and manufacture, their main problem is that their efficiency depends on their relative position relative to the sun. Sphelar is small and is designed to absorb sunlight from any angle. The design and geometry of Sphelar cells make it more efficient than flat solar panels. Solar energy is a promising type of renewable source of energy since we can produce vast amount of energy without harming the environment. Due to this, several methods to capture sunlight has been used and there is still so many methods to discover throughout the upcoming years. The spherical system is a promising one and is the most efficient design found till today but in time more efficient methods will be discovered by scientists.
