New Nanoparticle Could Lead to Inkjet-Printed Solar Cells

Jun-16-14 Researchers have developed a new class of quantum dots that could make solar power more affordable for everyone.

Colloidal quantum dots are the key materials in a new field of research centered around creating extremely efficient solar cells. Building the solar cells using CQDs requires two types of semi-conductors: n-type and p-type. However, the n-type materials will bind with oxygen if they are exposed to the air, causing them to give up their electrons and rendering them useless.

The nanoparticle created by the team from the University of Toronto is made of a new type of CQD n-type lead-sulfide material, and does not bind with oxygen. This improves the performance of the solar cell, which in turn could lead to improved weather and communication satellites, remote controls and pollution sensors. And even more exciting, the dots could be mixed in paints or inks and then be applied to a thin, flexible surface like roofing shingles, which would significantly lower the cost of solar technology and make it accessible to many more people.
