Environmental lifecycle assessment of PERC solar modules
IEA PVPS Task 12 analyzes the environmental impact of passivated emitter and rear cell (PERC) technology in PV installations in comparison to the monocrystalline silicon technology (AI-BSF) and the trend towards installing horizontal single-axis tracker systems as opposed to fixed tilt systems.
New design for organic/CIGS tandem solar cells promises 27.46% efficiency
Scientists in the Middle East designed a flexible two-terminal organic/CIGS tandem solar cell for wearable applications. The device achieved an open-circuit voltage of 1.89 V, a short-circuit current density of 17.55 mA/cm2, and a fill factor of 82.79%.
