New Solar Tech Harvests 85 Percent of Light
September 13, 2018 | Leave a Comment
Hokkaido University scientists have developed a photoelectrode that can harvest 85% of visible light. It is built in a 30 nanometers-thin semiconductor layer sandwiched between gold layers, converting light energy 11 times more efficiently than previous methods. The research team, led by Professor Hiroaki Misawa of the Research Institute for Electronic Science at Hokkaido University, […]

New Process May Create Higher Efficiency Solar Cells
September 6, 2018 | Leave a Comment
A team of semiconductor researchers based in France has used a boron nitride separation layer to grow indium gallium nitride (InGaN) solar cells that were then lifted off their original sapphire substrate and placed onto a glass substrate. The French team’s technique is the third major application for the hexagonal boron nitride lift-off technique, which […]

Breakthrough In Perovskite Solar Cells
July 10, 2018 | 1 Comment
University of Surrey researchers believe their new technique has produced the highest performing inverted perovskite solar cell ever recorded. Perovskite based cells are widely expected to be the next generation of solar cells, offering similar power conversion efficiency (PCE) performance, but at a much lower cost than today’s dominant crystalline silicon based solar cells. In […]

Lead Free Perovskite Solar Cell Proposed
June 14, 2018 | Leave a Comment
A Korea Advanced Institute of Science and Technology (KAIST) research team has proposed a perovskite material that serves as a potential active material for highly efficient lead-free thin-film photovoltaic devices. This material is expected to lay the foundation to overcome previously known limitations of perovskite including its stability and toxicity issues. The KAIST research team […]

Ecole Polytechnique Fédérale de Lausanne (EPFL) researchers have combined silicon and perovskite materials making a tandem solar cell. The resulting efficiency of 25.2 percent is a record for this type of tandem cell. Their innovative yet simple manufacturing technique could be directly integrated into existing production lines, and efficiency could eventually rise above 30 percent. […]
