How PV grid-tie inverters can zap utility power factor
Large grid-tie inverter systems are becoming more prevalent, and export energy credits from feed-in-tariffs help defray the large capital expenditure -- but a sub-par power factor could bring penalty charges from your utility. Gerritt Lee explains the problem and offers a solution.

Improving PV production efficiency through inkjet printing
Inkjet printing of contacts and bus bars improves production efficiencies -- less damage, fewer defects, and finer linewidths than silver paste, squeegee, or screen printing -- at one-fifth the cost, explains Trident Solar's Steve Liker.

High-speed ablation of dielectric SiN layers in silicon PV cells
Changing the thickness of a SiN coating layer can allow its use as an efficient anti-reflection coating for the front side of the solar cell. To link between the emitter and frontside or backside contacts, the coating must be opened up. A better approach to SiN removal, writes Jenoptik's Klaus Stolberg, is to select the laser source in such a way that the laser energy is absorbed in the coating directly.
