The Netherlands has developed a 360-degree green solar cell component

By embedding nano-silicon cylinders in dense arrays of solar panels, Dutch researchers have shown green energy to be
“green”.
In a new study published this week in the journal of applied physics letters, the combination of silicon heterojunction solar
cells with nano-silicon scattering media makes the components look green. The power of the panels will fall due to the
inability to absorb green light, but the decline rate is only about 10%. This paves the way for the development of high-
efficiency color components and the white photovoltaic integration building.
AMOLF researchers and chief author VerenaNeder said: “some people may not understand why we make the battery
efficiency low, but we can make the battery more beautiful under no exceed loss. This new method of changing battery
color is not only easy to operate, but also an attractive architectural design element and has many potential USES.
Unlike the current color of solar cells, the nano-pattern doesn’t change from any point of view, even when viewed from the
side. The researchers will design red and blue solar cells in the next step. Once these three colors are successfully
developed, we can make any color component, even white, by using the three colors of the light. Metal injection molding
parts is a good choice for the battery shell, which is more cost effective than CNC machining.
Albert Polman, group leader and thesis lead author of AMOLF research and development, said: “the combination of
different nanoparticles will affect the color of the molecules when they are very close to each other. Getting white is a big
challenge.”
Most research is focused on improving efficiency and cutting costs, and it is rare to see such aesthetic and efficiency
superimposed innovation.
