Ultrathin CIGS cell based on tungsten disulfide promises 25.7% efficiency
The novel solar cell uses tungsten sulfide as the back surface field layer. According to its creators, this layer can be included in conventional CIGS solar cells to improve their efficiency and reduce the absorber material’s cost.
Port of Riga to host 100 MW solar plant
Lithuania’s SNG Solar is set to build a 100 MW solar plant in the port of Riga, Latvia. Upon completion, the facility will be one of the largest solar projects in the Baltics.
Inside solar panel decommissioning
The practical matter of taking a dead PV system apart and moving its components to their next destination has received less attention than recycling and second-life applications. In the United States, Decom Solar is offering decommissioning for commercial and industrial (C&I) solar projects. pv magazine spoke to Decom Solar co-founder Stephen Burns for an update.
End of the line for a U.S. solar giant
SunPower, one of the largest, oldest, and most influential solar businesses in the United States, has closed its doors. Residential solar installers in the United States have struggled as interest rates have risen and cash generation has emerged as an issue.
RE+ 2024: Key takeaways on the U.S. solar industry
The 4.9 earthquake that shook Anaheim on the last day of RE+ 2024 did little to rattle the enthusiasm seen and felt at the largest energy conference in North America.
Scientists design all-back-contact transparent solar cell
A research team from South Korea’s Ulsan National Institute of Science & Technology (UNIST) has designed a wire-free transparent solar cell and module with all electrical contacts placed on the rear side.
