The investigation had been led by University of Toronto researcher Illan Kramer, just who calls the machine sprayLD. Much just like many earlier spray-on solar power designs, sprayLD utilizes colloidal quantum dots (CQD). CQD are tiny, light-sensitive dots—invisible into the naked eye—that can behave as an absorbing photovoltaic material. Technology has long held promise, although means of including light-sensitive CQD’s onto areas happens to be pricey, sluggish and laborious.

Just what Kramer along with his peers have inked is to invent a totally brand new, low priced, efficient way of creating solar panels utilizing CQD. They founded the method on a newspaper-printing process, and describe “SprayLD blasts a liquid containing CQDs straight onto versatile areas, including film or synthetic… by applying ink onto a roll of paper. This roll-to-roll coating strategy tends to make integrating solar cells into current manufacturing procedures much easier.”

As with regards to their prototype, the group admits it may look “more like junkyard conflicts than high-tech, ” but that’s since it ended up being made completely from inexpensive, easily available parts; U of T explains “[Kramer] sourced a spray nozzle found in steel mills to cool metallic with a superb mist of water, and some regular air brushes from a skill shop.”

Which possibly causes it to be all the more surprising that strategy doesn't seem to trigger any major drop offs in effectiveness. However, performance is still a significant consideration with spray-on solar power. The sprayLD system converts about 8.1percent of sunlight to energy, instead of 15-20% for standard rooftop solar arrays. But, speaking to Co.Exist, Kramer explained that as he is working on improving sprayLD’s efficiency “we consider ourselves as operating in a slightly different paradigm, in which we don’t need to be quite as efficient because we’re so much less expensive.”
