New method to find right tilt angle for PV systems located in high-latitude, cold regions

A group of researchers from Sweden has developed a new model to find the optimal tilt angle in PV installations located at high latitudes. The new approach takes into account, among other factors, the effect of transmittance change based on snow.

First attempt to build selenium-silicon tandem solar cells

Scientists in Denmark attempted for the first time to build a selenium-silicon tandem solar cell and found the device was immediately able to deliver a remarkable open-circuit voltage. Despite its current low efficiency levels, the new cell concept promises to reach efficiencies over 40%, according to its creators.
