New materials and processes to make the manufacturing and use of solar cells more efficient

For decades, solar technology and applications have been dependent on dye-sensitised solar cells (DSSCs). To mimic nature's absorption of light during photosynthesis, DSSCs use a photoactive dye that absorbs photons and uses their energy to excite electrons, which are then transferred into a nanocrystalline titanium dioxide layer. Although this process works well, the high-temperature processing required for titanium is not compatible with low-cost fabrication methods – an impediment to the mass market production of solar panels and thus a roadblock to increased use of solar energy.
