A solar cell is also known as a photovoltaic cell, which implies that it converts the photons present in the light into a voltage difference (which essentially means “electrical power”). To understand the limitations of a solar cell, we must take a closer look at its construction.
Efficiency of solar panels represents how much of sunlight that hits a solar cell gets transformed into electricity. Some of the first solar panels had efficiencies between 8 to 10 percent. Other traditional sources of energy had efficiency of 40 to 55 percent with the combined cycle generators [2].
Solar Performance and Efficiency. The conversion efficiency of a photovoltaic (PV) cell, or solar cell, is the percentage of the solar energy shining on a PV device that is converted into usable electricity. Improving this conversion efficiency is a key goal of research and helps make PV technologies cost-competitive with conventional sources .
Commercially available solar panels now routinely convert 20% of the energy contained in sunlight into electricity, a truly remarkable feat of science and engineering, considering that it is theoretically impossible for silicon-based solar cells to be more than 32% efficient.

How solar energy became cheap: a model for low-carbon innovation. (Taylor & Francis, 2019). Rogers, E. Diffusion of Innovations. (Free Press, 2003). Farmer, J. D. & Lafond, F.
Can solar panels convert sunlight into electricity?
Shockley-Queisser and the limits to converting sunlight into electricity Commercially available solar panels now routinely convert 20% of the energy contained in sunlight into electricity, a truly remarkable feat of science and engineering, considering that it is theoretically impossible for silicon-based solar cells to be more than 32% efficient.
Why do solar panels have a higher conversion efficiency?
On industry levels, regular advances and improvements in photovoltaic technology over time are the main reason behind efficiency improvements over time. In recent years, the average conversion efficiency of solar panels has increased from 15% to more than 21%.
How do solar photovoltaic cells work?
Solar photovoltaic cells are grouped in panels, and panels can be grouped into arrays of different sizes to power water pumps, power individual homes, or provide utility-scale electricity generation. Source: National Renewable Energy Laboratory (copyrighted)
Are semiconductors necessary to realize photovoltaic effect?
Conceptually, the semiconductors are not essential to realize photovoltaic effect though they are used in all solar cells now. In dye sensitized solar cells (DSSC), the semiconductors (i.e. ZnO and TiO2) are not used because of their semiconducting properties; they are merely used as an electron carrier and hole blocker.
