Major advance in fabrication of low-cost solar cells also locks up greenhouse gases

Perovskite solar cells have progressed in recent years with rapid increases in power conversion efficiency (from 3% in 2006 to 25.5% today), making them more competitive with silicon-based photovoltaic cells. However, a number of challenges remain before they can become a competitive commercial technology. Now a team at the NYU Tandon School of Engineering has developed a process to solve

Advanced solar tech to run cooler and last longer

Australian photovoltaics researchers have made a ‘cool’ discovery: Singlet fission and tandem solar cells — two innovative ways to generate solar power more efficiently — also help to lower operating temperatures and keep devices running for longer. Tandem cells can be made from a combination of silicon — the most commonly used photovoltaics material — and new compounds like perovskite

Quantum mechanics to pave the way for more stable organic solar cells

Quantum mechanics can be used to create more stable and more easily produced organic solar cells. These are the findings of new research from the University of Gothenburg. Organic solar cells have many advantages compared with traditional silicon-based solar cells. They can be manufactured cheaply at a large scale using printing presses, and they are light, malleable and flexible. The

Defect that limits hybrid perovskites solar-cell performance identified

Researchers in the materials department in UC Santa Barbara’s College of Engineering have uncovered a major cause of limitations to efficiency in a new generation of solar cells. Various possible defects in the lattice of what are known as hybrid perovskites had previously been considered as the potential cause of such limitations, but it was assumed that the organic molecules

Fraunhofer ISE to Set New World Record of 26 Percent Efficiency for Both-Sides-Contacted Solar Cell

A team of researchers led by Dr. Armin Richter of the Fraunhofer Institute for Solar Energy Systems ISE achieved a record conversion efficiency of 26.0 percent for both-sides contacted silicon solar cells. In the recently published Nature Energy article “Design Rules for High-Efficiency Both-Sides-Contacted Silicon Solar Cell with Balanced Charge Carrier Transport and Recombination Losses” Download [nature.com], Richter explains the structure
