AFM can help improve PV materials in 3 critical areas:

• Increasing the power conversion efficiency
• Developing lower cost materials and processing techniques
• Lengthening the useful service lifetime of photovoltaic devices

Specific examples include:

• Characterizing additives that increase perovskite grain size and improve efficiency
• Investigating ion migration at perovskite grain boundaries
• Correlating optical (photoluminescence) data with nanoelectrical AFM measurements
• Characterizing the ferroelasticity of perovskite films
• Improving the stability of electron transport layers for improved efficiency
• Optimizing additive concentrations in organic semiconductor films
• Evaluating molecular weight effects in organic semiconductor materials
• Measuring and understanding photocurrent heterogeneity
• Studying the affect of humidity on organic semiconductor film aging and reliability

Capabilities described include:

• MFP-3D Infinity Photovoltaics Option for simultaneous illumination of PV materials during AFM characterization
• Characterizing morphology and structure
• Measuring nanoscale photocurrent and other electrical properties
• Measuring nanomechanical properties and electromechanical response
