Dye-sensitized solar cells attain a new power conversion performance record
Mesoscopic dye-sensitized solar cells (DSCs) were designed in 1990s by Brian O'Regan and Michael Grätzel, taking on the latter's name-- the world-famous Grätzel cells. DSCs convert light into electrical power via photosensitizers-- dye compounds that absorb light and inject electrons into an array of oxide nanocrystals which ultimately are collected as electrical current.

3D chemistry increases perovskite efficiency to 23.9%.
A global cooperation led by EPFL chemical designers has actually gotten rid of a trouble in the manufacturing of perovskites that decreases their performance as solar panels. The strategy produced perovskite solar panels with an effectiveness of 23.9 percent and functional security longer than 1000 hours.

Removing the lead risk from perovskite solar cells
Although they provide a very encouraging service for recording solar energy, perovskite solar cells consist of lead, which is toxic to the atmosphere as well as a major health hazard. EPFL scientists have actually currently discovered a really sophisticated and also efficient service to this, by including a clear phosphate salt that does not interfere with light-conversion efficiency while protecting against lead from permeating into the dirt in cases of photovoltaic panel failing.
