About 1 % solar conversion efficiency was achieved by 1914 with the selenium cell. In 1954, experiments on semiconductors at Bell laboratories showed that doped silicon was unusually sensitive to light. Thus, the development of the first practical P–N junction PV solar cell took place. The further experiments on these solar cells, which had an efficiency of 6 % …
2019: Researchers at the National Renewable Energy Laboratory (NREL) break the record by developing a silicon solar cell with 39.2% efficiency under “one-sun illumination.” Another variation of the cell is able to achieve 47.1% efficiency under concentrated illumination.
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.
It wasn’t until 1954 that we really began to see an increase in solar cell efficiency when Bell Labs created the first silicon solar cell, which was able to reach almost 6% efficiency. The following year, Hoffman Electronics created the first commercial silicon solar cell, with which they achieved 2% efficiency.
An altogether different kind of approach is used in this method. In this process, temperature of substance is raised by using incident light thermal radiations. Thus black body radiation spectrum of material is shifted to shorter wavelength side. These shorter wavelength photons are used to increase efficiency of solar cells.
Space solar spectrum is different and solar cells could have better efficiency in space due to no atmospheric effect there. Capturing the total solar spectrum is the necessity to achieve higher output voltage in photovoltaic effect. The output of a solar cell depend on irradiance of solar spectrum as well as number of junctions in the solar cell.

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 of energy.
The VOE value defines the maximum allowable added manufacturing cost if solar cell efficiency is increased by 1%. This tool is meant to provide guidance for researchers and PV manufacturers to assess the economic validity of innovations and the fabrication costs that should be targeted.

Organic-inorganic halide perovskite solar cells (PSCs), as a new emerging yet very promising photovoltaic technology, continue to approach their theoretical efficiency limit thanks to worldwide research efforts. 1, 2 Perovskite was first introduced into a dye-sensitized solar cell by Miyasaka and co-workers 3 in 2009, but it demonstrated merely 3%–4% efficiency.
Recent advancements in graphene-based solar cells increased their efficiency by roughly 20% by reducing incident light reflection (Loh et al., 2016). Graphene can be doped in different ways to enhance the efficiency. The only difference between graphene-based and inorganic solar cells is that graphene or materials derived from graphene replace inorganic …
