In this episode of Great Question: A Manufacturing Podcast, Laura Davis examines the latest technological breakthroughs reshaping our world.

In this episode of Great Question: A Manufacturing Podcast, Laura Davis, the editor in chief of New Equipment Digest, explores groundbreaking technologies shaping our tomorrow from energy solutions to retail innovations and immersive entertainment to smart clothing. This episode unpacks the latest developments driving technological progress across multiple sectors. 

Below is an excerpt from the podcast:

We've got four new developments to discuss today. The first on the list is related to solar tech.

As big as solar tech currently is, I thought it would be more ubiquitous by now, but I only see applications for it few and far between. That might change though with a new development from Oxford University. Scientists at Oxford University Physics Department have developed a new way to generate solar electricity without the need for silicon-based solar panels with a new power-generating material that can be coated onto the surfaces of everyday objects. The light-absorbing material is thin and flexible, making it possible to apply to almost any surface, including buildings. The technique, developed in Oxford, stacks multiple light-absorbing layers into one solar cell, allowing the surface and materials to harness a wider range of the light spectrum and generate more power from the same amount of sunlight.

According to Oxford, the material has been independently certified to deliver over 27% energy efficiency, for the first time matching the performance of traditional, single-layer, energy-generating materials known as silicon photovoltaics. Japan's National Institute of Advanced Industrial Science and Technology certified the researcher's scientific study. According to Dr. Shuaifeng Hu, a post doctoral fellow at Oxford University Physics, in just five years of experimenting with their stacking or multijunction approach, they have raised power conversion efficiency from around 6% to over 27%, which is close to the limits of what a single-layer photovoltaic can achieve today. He followed up with that the team feels they can get the photovoltaic devices to achieve efficiencies greater than 45% over time.  When compared to the 22% energy efficiency of solar panels currently, it seems promising. But the flexible material is also a key player here. At just over one micron thick, it's almost 150 times thinner than a silicon wafer. Unlike existing photovoltaics generally applied to silicon panels, this can be applied to almost any surface.

New materials that can be applied as a coating have demonstrated the ability to replicate and exceed silicon's performance while adding flexibility. This breakthrough is significant because more solar power can be generated without relying so heavily on silicon-based panels or dedicated solar farms. The researchers believe that this innovative solar material and technique could provide a new platform for the industry by reducing the need for silicon panels and purpose-built solar farms as these materials can be manufactured and placed on existing buildings, vehicles, and objects, increasing sustainability and saving costs.
