The photonic curing technology used by the PulseForge was designed specifically with these production characteristics in mind, and DuPont was attracted to the PulseForge's ability to advance their efforts in printing radio-frequency identification tags, and the thin-film semiconductor
layers and fine-line microcircuitry crucial to flexible displays.
Amorphous silicon (a-Si) is the oldest and most widely used thin-film semiconductor
. It's not as efficient as crystalline silicon, but less expensive.
"Only with Nanosolar working out ways of printing CIGS, the most efficient and most stable thin-film semiconductor
, has it been possible to bring the economics of printing to solar in a way that has large market reception," Mr.
Energy Conversion Devices Inc (ECD Ovonics) (Nasdaq:ENER) announced on Wednesday (28 December) that its 39.5%-owned joint venture Ovonyx Inc and Samsung Electronics Co Ltd have entered into a long-term license agreement under Ovonyx intellectual property relating to Ovonic Universal Memory (OUM) thin-film semiconductor
Feldman, head of thin-film semiconductor
research at AT&T Bell Laboratories in Murray Hill, N.J.
"We have developed a new, high-pressure, plasma-free approach to creating large-area, thin-film semiconductors
," said John Badding, professor of chemistry, physics, and materials science and engineering at Penn State and the leader of the research team.
While most solar cells today are made of crystalline silicon, cells based on inorganic and organic thin-film semiconductors
deposited on a flexible support are receiving growing interest.
