How does the solar energy work?

Solar energy technology work by converting sunlight into electricity. Sunlight is needed to excite electrons in a photovoltaic(PV) material, also called a solar cell. Solar cells or photovoltaic (PV) cells work using the photoelectric effect principle where electrons in a semiconductor material are excited giving rise to free electrons that move in one direction through a PN junction. Semiconductor materials are used in solar cells because they exhibit the characteristics…

What is the best solar panel efficiency?

The ability of a solar cell or photovoltaic (PV) material to convert a percentage of the solar energy shining on it into usable electricity is known as solar panel efficiency. One of the technological breakthroughs of photovoltaics or solar cells will depend on how to increase solar panel efficiency with reduced material costs.  So far, this technological breakthrough has been achieved partially only with regards to high solar efficiencies as…
