Abengoa Solar in Seville had installed a solar panels of Concentrix Solar. Those panels are 23 % efficient.
The 23% or better AC efficiency reflects the actual electricity fed into the grid after sunlight is first converted into DC (Direct Current) by the photovoltaic modules and then into AC by the inverter under actual field conditions.

The average efficiency of regular solar panels is 15 percent; thin-film solar cells register a lower efficiency percentage than that. Japan’s National Institute of Advanced Industrial Science and Technology (AIST), however, claims 17.7 percent efficiency for its flexible thin-film CIGS solar cell. To be able to achieve that impressive percentage, AIST devised CIGS technology called [...]

In one of the most significant announcements in renewable energy for the year Nanosolar, producer of CIGS solar cells made using nanoparticle ink and roll-printing technology, announced that it has shipped its first product and received their first che…
