Swiss Firm Claims It Can Make Near Invisible Solar Modules

With the help of modern science and technology, researchers are trying to invent innovative things. Last Tuesday, Swiss research and development company Swiss Center for Electronics and Microtechnology (SCEM) said that it had developed a new technology paving the way to making the world’s first white solar modules with no visible cells and connections.


Invisible Solar Modules

The problem with the common blue-black solar modules, built to maximize sunlight absorption, is their “visually unaesthetic” appearance, which tends to hamper their acceptance. To solve the problem, SCEM said it had taken solar cell technology for converting infrared solar light into electricity and combined it with a special filter that “scatters the whole visible spectrum while transmitting infrared light”. This method made it possible for crystalline silicon-based solar technologies to be molded into modules that blend seamlessly with building surfaces in any color, including pure white.

Since the visible, reflected light will not contribute to heat, the solar cells are expected to work at temperatures 20 to 30 degrees Celsius below standard models, it said.

SCEM said, “The technology can be applied on top of an existing module or integrated into a new module during assembly, on flat or curved surfaces. White PV modules can also contribute to increase energy savings in buildings by keeping inner spaces cooler and reducing air conditioning costs.”
