They are made up of many small photovoltaic cells that are made of semi-conductors, usually silicon. When photons from the sun hit the cells, they knock electrons loose from their atoms. If there are conductors attached to the positive and negative sides of the cell, this will create an electric current. However, solar panels are not 100%
When light shines on a photovoltaic (PV) cell – also called a solar cell – that light may be reflected, absorbed, or pass right through the cell. The PV cell is composed of semiconductor material; the “semi” means that it can conduct electricity better than an insulator but not as well as a good conductor like a metal. There are several different semiconductor materials used in PV

The region over this discontinuity change occurs is called as the p-n homo-junction. Homo-junctions are generally found in the elemental semiconductors such as Si and Ge, or the compound semiconductors
One reason is that today''s photovoltaic cells are relatively inefficient. They put out only about a quarter of the energy they take in from the sun. If that efficiency could be improved, solar panels could take up less real estate while pumping out more electricity. “At the end of the day, efficiency is the challenge with solar energy,” says Adrienne Stiff-Roberts, PhD, who is the Jeffrey

Solar panels are not very efficient because they can only be made of silicon photovoltaic cells. Silicon is one of the least efficient semiconductors available. This means that to make enough electricity for your house using solar power, you would need a huge surface area of solar panels, around 100 square feet per person.
Solar panel efficiency is the percentage of the sun's energy that is converted into electricity. It is the ratio of power out divided by power in. for example, a 100-watt panel with an efficiency of 16% would have an output of 16 watts. The efficiency of the single-junction cell has limited the efficiency of solar panels.
The major factor that can affect the efficiency of solar panels is also weather conditions and seasons, as we're all aware in some of the countries around the world during fall and winter seasons days become drastically shorter.
The theoretical upper limit for high-efficiency solar cells is about 33.16% (±0.5%). There are currently commercially available multi-junction photovoltaic cells with efficiencies over 44%. NASA is working on a variety of technologies to achieve efficiencies greater than 100%.
