The emerging organic photovoltaic (OPV) technology is very promising for low-cost solar energy production.

The emerging organic photovoltaic (OPV) technology is very promising for low-cost solar energy production. OPV devices can be produced using high-throughput, large-volume printing methods on lightweight and flexible plastic substrates, making them easy to deploy and use in innovative ways.

Professor Chen (Nankai University, China) and his team explain the strategies behind their recent record-breaking organic solar cells, reaching a power conversion efficiency of 17.3%.

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
