Peel-and-stick thin film solar cells

 Kim and his colleagues devised an idea to produce a light-weight flexible solar cell on nonconventional or universal substrates that overcomes the limitations of traditional methods while maintaining performance. By doing so, Kim believed that his new cells could broaden the application spectrum of solar cells.

The success comes from using the same traditional fabrication method while adding a metal layer between the fabricated a-Si:H TFSCs and the underlying Si/SiO2 wafer. After numerous attempts and trials, Kim and his colleagues found a method to reliably peel the fabricated TFSCs from the Si/SO2 wafer by using water penetration between the metal layer and the SiO2 layer on the wafer.
