Photo by Wayne Hicks, NREL Researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) created a solar cell with a record 39.5% efficiency under 1-sun global illumination. This is the highest efficiency solar cell of any type, measured using standard 1-sun conditions.
In the fifth section, the development and status of a variety of high-efficiency solar cell devices such as PERC, PERL, PERT, Pluto-PERC, Pluto-PERL, IBC, EWT, MWT and HIT are carefully reviewed. The design concept, unique feature and competitive advantage of every high-efficiency Si solar cell device are highlighted.
Among all the high-efficiency devices that are reviewed in this chapter, PERC, PERL and HIT solar cells are most promising for mass production in industrial scale due to the minimization of the use of high-temperature processes and photolithography techniques.
Surprisingly, the efficiency of 22.8 % for thinner-substrate (98 μm) is comparable to the best efficiency of 23.0 % for standard substrate (250 μm). Reducing the thickness of the substrates by more than 50 % and maintaining its efficiency at the same time provides the possibility of further reducing the cost production of HIT solar cells.
This is a global milestone, as there is currently no solar cell with a higher efficiency worldwide. The results are presented today at the 2nd Interna-tional tandemPV Workshop, taking place in Freiburg, Germany.
The efficiency of double-side contacted SHJ solar cells reached 25.1% in 2015, surpassing the champion efficiency of homojunction PERC cell, thanks to the breakthrough of a high FF over 83% .
Status and Progress of High-efficiency Silicon Solar Cells
Here we will not elaborate on Si thin-film solar cells because they are out of the subject of high efficiency due to their lower efficiencies (~10 %) in comparison with c-Si wafer solar cells, although a record efficiency of 13.1 % has been achieved based on a "micromorph" tandem Si thin-film solar cell consisting of a top a-Si:H cell and a bottom microcrystalline Si (μc …

High-Efficiency Solar Cells
Another contributor to the high quality of GaAs as a solar cell is what happens after a photon is absorbed. We noted in the second chapter that one of the phenomena that limits solar cell efficiency is the recombination of electron-hole pairs before they can be extracted into the external circuit. There are in fact many mechanisms by which ...
