Transparent Solar Cells May Be Used in Your Home Windows, This Is the Future of Renewable Energy

A research team from the University of Michigan said it has established a new efficiency record for transparent solar cells with neutral colors. Instead of following the conventional silicon-based design, the team achieved 8.1% efficiency and 43% transparency with an organic/carbon design. The solar cells carry a greenish hue, but resemble the gray color of sunglasses and car windows.

According to lead researcher Stephen Forest, these organic solar cells are compatible with windows that cover the facades of most buildings. Organic cells offer the winning combination of high efficiency and high transparency, which silicon does not provide.

Transparent Solar Cell Has a Lifespan of 10 Years

Mercom had previously reported on Australian scientists, led by members of the ARC Center of Excellence in Exciton Science, who published research stating they successfully produced semitransparent perovskite solar cells that generate electricity. This discovery could enable windows in buildings and cars to generate electricity.

The new material is a combination of organic molecules designed to be transparent in the visible spectrum and absorbent in the near-infrared, an invisible part of the spectrum responsible for much of the energy in sunlight. Additionally, researchers developed optical coatings to enhance both the power generated by infrared light and the transparency in the visible range – two qualities that typically compete with each other.

The neutral-colored version of the device was made with an indium-tin oxide electrode. A silver electrode improved the efficiency to 10.8%, with 45.8% transparency. However, the slightly greenish hue of this version may not be acceptable in some window applications.
