MARKET RESTRAINTS
Material Limitations in Near-Infrared Spectrum to Constrain Applications
While silicon photodiodes demonstrate excellent performance in visible light applications, their quantum efficiency drops significantly beyond 1000nm wavelengths. This inherent material limitation restricts their use in critical infrared sensing applications where III-V compound semiconductors like InGaAs dominate. Approximately 35% of photodetector applications requiring sensitivity above 1100nm currently cannot utilize silicon-based solutions. The bandgap characteristics of silicon create fundamental performance boundaries that alternative materials must address, potentially limiting market expansion into emerging infrared imaging sectors such as thermal vision and spectroscopic analysis.
Manufacturers face additional challenges in achieving consistent performance across production batches. Silicon wafer defects and doping inhomogeneities can cause variation in dark current levels by up to 15% between devices, requiring extensive quality control measures that increase production costs. These technical constraints create adoption barriers in applications requiring extreme reliability such as aerospace and medical diagnostics.
MARKET CHALLENGES
Global Semiconductor Supply Chain Disruptions to Impact Production
The silicon photodiode market faces significant challenges from ongoing semiconductor supply chain volatility.
