Seeing Down to the Bottom: Nondestructive Inspection of All‐Polymer Solar Cells by Kelvin Probe Force Microscopy

The material composition in a bulk heterojunction (BHJ) of an all-polymer solar cell is analyzed down to the bottom surface by Kelvin probe force microscopy. The phase separation of the composites both on the top and at the bottom of a BHJ can be measured and reconstructed with this easy-to-use approach in a nondestructive way.
