GOOD NEWS: Scientists develop more efficient transparent solar panels

GOOD NEWS: Swiss scientists have developed transparent solar panels that set a new record in energy efficiency. The accomplishment marks a key step in the development of windows that can also serve as viable sources of solar energy.


  • The transparent solar panels, known as dye-sensitized solar cells (DSCs), use photosensitized dye attached to a semiconductor to convert light into energy.
  • Earlier forms of the technology were only capable of generating power from direct sunlight.
  • Scientists at the École Polytechnique Fédérale de Lausanne (EPFL) developed transparent panels that absorb light across the entire visible light spectrum.
  • “Our findings pave the way for facile access to high-performance DSCs and offer promising prospects for applications as power supply and battery replacement for low-power electronic devices that use ambient light as their energy source,” wrote the scientists in a study published in the journal Nature.
