Photovoltaic (PV) efficiency refers to the ability of a photovoltaic device, such as a solar cell or solar panel, to convert sunlight into usable electrical energy. It is expressed as a percentage and represents the ratio of electrical power output to the amount of sunlight (solar energy) input.
Photovoltaic (PV) cell technologies are rapidly improving, with efficiencies reaching up to 30% and costs falling below $ 0.50/W, making PV a competitive source of energy in many countries around the world. Solar PV technology holds immense potential for creating a cleaner, reliable, scalable, and cost-effective electricity system.
The performance and efficiency of solar PV vary according to types of cells. The mono-crystalline solar cells feature high energy efficiency, but it has a complex manufacturing process. The multi-crystalline solar cells are cost-effective but suffer from low efficiency in comparison to mono-crystalline solar cells.
Trends in photovoltaic (PV) efficiency improvement include incremental advances, the emergence of tandem solar cells stacking multiple materials for enhanced efficiency, the growing prominence of perovskite solar cells due to rapid efficiency gains, and the increasing popularity of bifacial solar panels capturing sunlight from both sides.
The power conversion efficiency of a solar cell is a parameter that quantifies the proportion of incident power converted into electricity. The Shockley-Queisser (SQ) model sets an upper limit on the conversion efficiency for a single-gap cell.
The photovoltaic sector is now led by silicon solar cells because of their well-established technology and relatively high efficiency. Currently, industrially made silicon solar modules have an efficiency between 16% and 22% (Anon (2023b)).
