The chip for a power-optimization device
Chinese photovoltaic giant Suntech is investing in electronics to help squeeze more power out of solar arrays: smart module power-optimizers that correct for a drop in the array’s power output due to shading or debris and microinverters that adjust the voltage-current levels of each panel.

Schematic of dye sensitzed solar cell
SolarPrint has developed a process to replace the liquid in dye sensitized solar cell (DSSC) technology with a printable electrolyte paste. The fully printable cells can be turned out fast and cost-effectively, and are more efficient due to their nanostructure components.
