Swiss scientists have reached a new efficiency record for see-through solar panels that are being used in skylights, greenhouses, and glass facades. paving the way for windows that generate electricity. Dye-sensitized solar cells (DSCs) are low-cost solar cells that convert visible light into energy. While energy-generating windows have been on the market for some years, their capacity was lower than traditional solar cells. The new breakthrough could help overcome that barrier. The new molecule design developed by the scientists at the École Polytechnique Fédérale de Lausanne has increased the power conversion efficiency of DSCs -- in other words, the share of the solar energy shining on them that is converted into usable electricity.
