Nano Ink Boost for Silicon Solar

Ink-jet-printed silicon increases solar-cell efficiency. Inkjet solar: The inkjet printing process allows Innovalight to make silicon wafers that are thin enough to bend. A California company is using silicon ink patterned on top of silicon wafers to boost the efficiency of solar cells. The Sunnyvale, CA, firm Innovation says that the inkjet process is aRead More

A New Way to Use the Sun’s Energy

Bright heat: Nicholas Melosh has developed a device for simultaneously converting the sun’s light and heat into electricity. Melosh makes and tests the device in this vacuum chamber in his lab at Stanford University. Researchers have demonstrated a new mechanism for converting both sunlight and heat into electricity. A new type of deviceRead More
