Two Queen´s researchers have contributed to a significant breakthrough in solar technology. Their research has led to a new solar photovoltaic thermal (PVT) system that generates both electricity and heat. Solar PVTs are normally made with crystal silicon cells which generate electricity, but little heat. Stephen Harrison and Joshua Pearce (Mechanical and Materials Engineering) designed and tested amorphous silicon cells in a PVT system. Their research shows increased heat generation...

New Solar Cells Shine With Potential

Today´s solar cells have several limitations, including high production costs, low efficiency and durability, and reliance on scarce materials for production. Now, a group of Northwestern University researchers say they have developed a new solar cell that minimizes these problems. The device uses a Grätzel cell, a promising low-cost and environmentally friendly solar cell with a significant disadvantage: it leaks. The dye-sensitized cell's electrolyte is made of an...

Taking their cue from the humble leaf, researchers have used microscopic folds on the surface of photovoltaic material to significantly increase the power output of flexible, low-cost solar cells. The team, led by scientists from Princeton University, reported online April 22 in the journal Nature Photonics that the folds resulted in a 47 percent increase in electricity generation. Yueh-Lin (Lynn) Loo, the principal investigator, said the finely calibrated folds on the surface of the...

The public is being kept in the dark about the viability of solar photovoltaic energy, according to a study conducted at Queen´s University. “Many analysts project a higher cost for solar photovoltaic energy because they don´t consider recent technological advancements and price reductions,” says Joshua Pearce, Adjunct Professor, Department of Mechanical and Materials Engineering. “Older models for determining solar photovoltaic energy costs are too...


Word of the Day
vermicular
  • Like a worm in form or movement; vermiform; tortuous or sinuous; also, writhing or wriggling.
  • Like the track or trace of a worm; appearing as if worm-eaten; vermiculate.
  • Marked with fine, close-set, wavy or tortuous lines of color; vermiculated.
  • A form of rusticated masonry which is so wrought as to appear thickly indented with worm-tracks.
This word ultimately comes from the Latin 'vermis,' worm.
