Based on the Grätzel cell, the new cell uses millions of light-absorbing nanoparticles and delivers the highest conversion efficiency reported for a dye-sensitized solar cell."
The most exciting phrase to hear in science, the one that heralds new
discoveries, is not "Eureka!" (I found it!) but "That's funny ..."
