Time-reversal asymmetry surpasses conversion efficiency limit for solar cells

  • 1 week ago

Solar energy is a popular candidate for a sustainable alternative to fossil fuels. A Solar cell, or photovoltaic (PV) cell, converts sunlight directly into electricity. However, the conversion efficiency has not been enough to enable widespread applications of Solar cells. A fundamental limit to the maximum efficiency of PV devices is given by thermodynamic characteristics, namely temperature and entropy (a measure of disorder in a system). More specifically, this limit, known as the Landsberg limit, is imposed by the entropy of the blackbody radiation that is often attributed to sunlight. The Landsberg limit is widely considered as the most general limit for the efficiency of any conv ...

Reversible fuel cells can support grid economically by Staff Writers Stanford CA (SPX) Apr 22, 2022 A reversible solid-oxide fuel cell system in Dresden, Germany. A major challenge for producers of electricity from solar panels and wind turbines is akin to capturing lightning in a bottle. Both solar and wind increasingly generate electricity amid little demand, when market prices are too low to cover costs. At noon on sunny days, for example, wholesale power prices in areas with high quantities of solar and wind occasionally fall below zero. Some renewable energy producers store their excess electricity as green hydrogen, using the electricity to pr ...

Illuminating perovskite photophysics

  • 1 month ago

A detailed view of how electrical charges behave inside perovskites could guide efforts to improve the performance of next-generation Solar cells based on these materials, KAUST research has shown. When light hits a perovskite, it excites negatively charged electrons and leaves behind positively-charged "holes" within the material's crystalline structure. These electrons and holes can then move through the perovskite to generate an electrical current. But the charge carriers could also recombine instead, which wastes the energy they carry. "The efficiency of perovskite Solar cells has been greatly improved in the past decade, but fundamental research on their photophysics is relatively ...

Everyone Wants to Build Green Energy Projects. What's the Holdup?

  • 1 month ago

For green energy experts, it seems like there’s too much of a good thing right now. While it’s great that there are enough wind, solar, and battery storage projects planned to meet the United States’ climate goals, a growing bottleneck in the nation’s electric grid is keeping most of these projects grounded. The problem stems from a combination of factors: aging infrastructure, a discombobulated electrical grid that makes it difficult to get renewable energy from where it is produced to where it is needed, and the overwhelmed regulators responsible for approving the projects. A new report by researchers at the Lawrence Berkeley National Laboratory outlines the dilemma. The author ...

But, in a typical single-junction Solar cell, performance is capped at what is called the Shockley-Queisser limit (a theoretical limit for the maximum efficiency that a Solar cell can reach). Efficiency determines how much of the light energy (photons) absorbed by the solar cell can be converted into usable electric current. The Shockley-Queisser limit puts the maximum possible efficiency at 33.7 percent for semiconductor-based solar cells. Over the years, scientists have explored and developed new paradigms for solar cell designs and material ...

A metal foam could underpin a low-cost method for generating carbon-free fuels, researchers from KAUST have shown. The team seamlessly coated the foam with iron and cobalt nanomaterials to create a highly active electrode for a device that splits water molecules to release oxygen and hydrogen, a potential green fuel. Due to the intermittent nature of wind and solar energy electricity, there is a need to develop methods to convert renewable electricity into a carbon-free fuel that could be stored and transported for later use. "Electrochemical water splitting is seen as a pragmatic route to reach this goal," says Pravin Babar, a postdoc in Cafer Yavuz's lab, who led the research. An elect ...

Predicting solar cell performance from terahertz and microwave spectroscopy

  • 3 months ago

The most important properties of a semiconductor to be used as a Solar cell include the mobility and lifetime of electrons and "holes". Both quantities can be measured without contacts with spectroscopic methods using terahertz or microwave radiation. However, measurement data found in literature often differ by orders of magnitude. This has made it difficult to use them for reliable assessments of material quality. Reference samples measured "We wanted to get to the bottom of these differences, and contacted experts from a total of 15 international laboratories to analyse typical sources of error and problems with the measurements," says Dr. Hannes Hempel from the HZB team led by Dr. ...
