Photovoltaics (PVs) are a key driver of sustainable technology. A PV panel is effectively a thin film stack of different semiconductor materials arranged in layers or junctions. In a typical solar PV system, an N-type semiconductor is layered over a P-type material, and it’s this PN junction that enables photons of light impinging on the solar panel to be harnessed for power generation. Given the exponential growth of energy demand and the continued depletion of fossil fuels, it’s unsurprising that the PV industry is going through a period of rapid growth. PVs are crucial for achieving climate neutrality by 2050. Experts predict the industry will increase its valuation from USD 96.5 billion to a staggering USD 155.5 billion by 2028. This growth will be driven by four key factors:

• Integrated applications
• High efficiencies (i.e. Tandem technology)
• Low ecological footprint
• Increased focus on circularity

Meeting this demand requires research and development (R&D) initiatives to be ramped up and manufacturing processes to be fully optimized. Advanced metrology solutions can play a critical role in this arena.

Improved Efficiency and Performance

Advanced metrology is crucial for boosting the effectiveness and performance of PV cells. It enables researchers to examine the electrical and optical properties of photovoltaic cells closely, providing insights into their potential performance. This knowledge allows developers to make cells more cost-effective and efficient. For instance, the transition from PERC to TOPCon technologies is anticipated in the coming years, while N-type materials gain market share due to passivated contacts (TOPCon & SHJ) technologies. At Semilab, we provide a range of advanced metrology tools, such as Spectroscopic Ellipsometry, which is particularly suitable for measuring TOPcon structures at various stages of the process, including the measurement of ~100nm poly-Si and even after the 1.5nm oxide has been separated. 

Quality Control and Process Monitoring

Advanced metrology is essential for quality control and process monitoring in the PV industry. Photoluminescence imaging, for instance, can be leveraged to monitor different types of wafers, such as multicrystalline, monocast, or monocrystalline. These tools can be incorporated into automated PV production lines, ensuring the quality of PV cells remains consistent throughout the manufacturing process.

Research and Development

Advanced metrology is a cornerstone for research and development in the PV industry. Our state-of-the-art laboratory tools help in developing new ways and techniques for producing high-efficiency solar cells. By working with customers to improve tool performance and introduce new applications, we help drive innovation in the PV industry.

Cost Reduction and Increased Productivity

Advanced metrology can help PV manufacturers cut costs and boost productivity. We provide measurement techniques that don’t damage the products or require contact. These techniques enable efficient monitoring of semiconductor devices, flat panel displays, and solar cells. They can help decrease downtime, boost PV efficiency, and enhance layer performance. This leads to lower production costs and higher yields.
