Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. The efficiency of the solar cells used in a photovoltaic system, in combination with latitude and climate, determines the annual energy output of the system.
Commercially deployed silicon-based photovoltaic cells are already close to the theoretical maximum energy conversion efficiency of 29 percent. This means that even with the best silicon-based solar cell, we are not converting over 70 percent of the solar energy received at a solar power plant.
In an attempt to promote solar energy utilization, this comprehensive review highlights the trends and advances of various PV cell technologies. The feasibility of PV cell technologies is accomplished by extending the discussion on generations of PV technology, PV building materials, efficiency, stability, cost analysis, and performance.
The two types of quantum that are usually referred to when talking about solar cells are external and internal. External quantum efficiency (EQE) relates to the measurable properties of the solar cell. The "external" quantum efficiency of a silicon solar cell includes the effect of optical losses such as transmission and reflection.
Abstract: Many manufacturers choose the passivated emitter and rear cell (PERC) approach in order to surpass the 20% cell efficiency level in mass production. In this paper, we study the efficiency potential of the PERC approach under realistic assumptions for incremental improvements of existing technologies by device simulations.
The maximum theoretical efficiency calculated is 86.8% for a stack of an infinite number of cells, using the incoming concentrated sunlight radiation. When the incoming radiation comes only from an area of the sky the size of the sun, the efficiency limit drops to 68.7%.

Solar Cell Efficiency Explained. Cell efficiency is determined by the cell structure and type of substrate used, which is generally either P-type or N-type silicon, with N-type cells being the most efficient. Cell efficiency is calculated by what is known as the fill factor (FF), which is the maximum conversion efficiency of a PV cell at the optimum operating voltage and …

Energy conversion efficiency is measured by dividing the electrical output by the incident light power. Factors influencing output include spectral distribution, spatial distribution of power, temperature, and resistive load.
