A COAT­ING OF SUN POWER

Gadgets and Gizmos (India) - - BIT RATE -

If you thought you needed so­lar pan­els on your roof to tap the sun’s power for your home, here’s news. Re­searchers at the Univer­sity of Notre Dame, US, have de­vel­oped a 'so­lar paint' for the out­side of a house to gen­er­ate power for de­vices in­side. The 'Sun-be­liev­able' paint uses semi­con­duct­ing nanopar­ti­cles to pro­duce en­ergy. It isn’t as much of a power gen­er­a­tor as so­lar pan­els, but it is af­ford­able and easy to pro­duce in large quan­ti­ties. “We want to do some­thing trans­for­ma­tive, to move be­yond cur­rent sil­i­con-based so­lar tech­nol­ogy,” says Pro­fes­sor Prashant Ka­mat, who led the re­search. Apaste of ti­ta­nium diox­ide coated with cad­mium com­pounds, when brushed on a trans­par­ent con­duct­ing ma­te­rial and ex­posed to light, pro­duces electricity.
