Scientists at CENIMAT are attempting to reduce the costs of harnessing the sun’s energy by creating ceramic tiles that can perform photovoltaic action, so-called “solar tiles” that can be used to tile roofs and walls.
Hugo Águas, Rodrigo Martins and their research group at CENIMAT:I3N laboratory of FCT-UNL and CEMOP-UNINOVA have successfully fabricated solar tiles and demonstrated market viability with a cost estimation. Their new solar tiles were able to achieve a 5% conversion efficiency and 80% quantum efficiency.
