Present State of Plastic Solar Cells

“The plastic solar cells will be commercialized soon!!”

Printed Modules

Gwangju Institute of Science and Technology develops a novel organic photovoltaic module architecture

Using an innovative series connection based on charge recombination That occurs at the contacts between charge transport layers large-area OPV modules Can be easily fabricated.

GIST develops a new patterning process for perovskite photovoltaic modules.

The monolithic module architecture for large area perovskite photovoltaic modules has a geometrical fill factor of 94.1%, a module efficiency of 14.0% and an area of 9.06cm2.
