Early Stages of Renewable Energy

May 29, 2024 Article

Scientists have discovered a new material that could radically improve the efficiency of next-generation solar panels.

“I am all in favor of growing the American economy and engaging in trade with the world, but not at the expense of American workers.” — Unknown

A team from Lehigh University in the US developed a material capable of achieving an absorption efficiency rate of 190 percent of the theoretical efficiency limit for traditional silicon-based solar cells. A hold-up has been learning how to mass-produce innovative materials.

“This work represents a significant leap forward in our understanding and development of sustainable energy solutions, highlighting innovative approaches that could redefine solar energy efficiency and accessibility in the near future,” said Chinedu Ekuma, a professor of physics at Lehigh University.

Unicorn Solar always believed that, at some point, the materials we use would be outdated and that a technological revolution would occur. Tests of the material showed that it performed remarkably well when absorbing infrared light and visible regions of the electromagnetic spectrum.

The material achieved an external quantum efficiency (EQE) of 190 percent an essential method for measuring the efficiency of a solar cell. The EQE rate represents the generation of one electron for each photon absorbed from sunlight. Collecting more than one electron from one photon is possible with the new material, thus accounting for such a high EQE rate.

To achieve this, the new material takes advantage of the ‘van der Waals gaps, which are atomically small gaps between layered two-dimensional materials. “Its rapid response and enhanced efficiency strongly indicate the potential of Cu-intercalated GeSe/SnS as a quantum material for use in advanced photovoltaic applications, offering an avenue for efficiency improvements in solar energy conversion,” said Professor Ekuma.

Unicorn Solar sees this as a promising candidate for developing next-generation, highly efficient solar cells, which will play a crucial role in addressing global energy needs.” We all know that technology goes through many generations over time. It is exciting to see we are developing a more efficient method of producing electricity via the sun and human innovation.

We have to remember that renewable energy is still in the early stages of its eventual development. Once I realized the value of renewable energy, I believed that renewables would power our industry and lives. Yes, the road is long and filled with many trials, but the value proposition to humanity and the planet enhances our lives. Schedule your meeting!
