The Japanese group described the cell in “Semi-transparent Perovskite Solar Cells for Four-Terminal Perovskite/CIGS Tandem Solar Cells,” which was recently published in ACS Publications.

Flexible, printed solar cells offer a wide range of possibilities. They can work indoors and they can be made semi-transparent, so they could be incorporated into windows and generate power during ...

MiaSolé's 20%-efficient CIGS cell was fabricated in a roll-to-roll process on steel foil. The 17.5%-efficient semi-transparent perovskite solar cell was developed on glass. The perovskite device ...
