Light reading

pun intended

I was just reading this:

"Nature's photosynthesis process far outperforms man-made light-energy-converting devices. The highly efficient mechanism for rapid separation and transfer of photo-excited charge pairs in the photosynthetic reaction center is a key step. In many thin-film solar-cell efforts, this charge separation is a critical challenge. In response, several fundamental studies have modeled nature's multistep charge-transfer process, which aids in precluding charge-pair recombination, or directly incorporated photosynthetic complexes into devices."

Makes sense to me

Oh, of course! Charge pairs!

Meanwhile, I read this Sunday's Peanuts comic to the boys...
