A Comparative Study of Evolution Stages of Different PV Cells used in Solar Power Generation

- Solar electric power generated via the direct conversion of solar radiation into electricity. Photovoltaic's enables humanity to make use of sunlight in a clean, everlasting, and highly versatile way. PV gets its name from the process of converting light (photons) to electricity (voltage), which is called the PV effect . The enormous growth in the world economy, reflecting both increases in population and rising affluence, is occurring on a planet that is no larger today than it was when we evolved some 4 million years ago. The consequences of increasing human demands on the natural systems and resources such as our fossil fuels of a finite planet are being felt in every country around the world. Photovoltaic's offer an alternative means of producing essential electric power without further endangering the delicate balance of our fragile ecosystems, and that is why the need has arrived for lowering the cost of solar energy. This can be achieved by improving the cell's efficiency.
