Scientists write 'traps' for light with tiny ink droplets

A microscopic 'pen' that is able to write structures small enough to trap and harness light using a commercially available printing technique could be used for sensing, biotechnology, lasers, and studying the interaction ...

Inkjet-printed batteries bring us closer to smart objects

The race is on to develop everyday objects that have network connectivity and can send and receive data: the so-called 'Internet of Things'. But this requires flexible, lightweight and thin rechargeable power sources. Currently ...

Inkjet printing process for kesterite solar cells

A research team at HZB has developed an inkjet printing technology to produce kesterite thin film absorbers (CZTSSe). Based on the inkjet-printed absorbers, solar cells with total area conversion efficiency of up to 6.4% ...
