Researchers prepare cheap quantum dot solar paint

(PhysOrg.com) -- It typically takes a day or two to prepare quantum dot solar cells in the conventional multifilm architecture. Now a team of researchers is reducing the preparation time of quantum dot solar cells to less than an hour by changing the form to a one-coat quantum dot solar paint. Although the paint form is currently about five times less efficient than the highest recorded efficiency for the multifilm form, the researchers predict that the efficiency can be improved, which could lead to a simple and economically viable way to prepare solar cells.
