Performance Metrics
Understanding the performance metrics tied to CIGS solar cells is essential for assessing their viability. Let’s delve into the critical metrics that matter:
Peak Power (Wp)
Peak Power Ratings for CIGS solar modules can vary, with high-efficiency models producing around 160–170 W per panel. These metrics are crucial for making informed decisions on solar installations based on energy needs.
Open-Circuit Voltage
The Open-Circuit Voltage for leading CIGS panels can range from 0.6 to 0.7 volts, a significant value that influences the design of entire solar installations. The greater the open-circuit voltage, the better the performance.
Short Circuit Current
CIGS panels can typically produce short-circuit currents ranging from 4.5–5.5 A. Understanding this metric is vital for deploying solar systems that can handle peak energy demands.
Max Power Voltage
Max Power Voltage figures can hover around 0.5–0.6 V, critical in designing systems to optimize energy output effectively, especially for commercial applications.
Max Power Current
Similar to short-circuit current, this can range between 4.0–5.0 A, allowing stakeholders to assess compatibility across different system configurations, ensuring optimal performance.
Conversion Efficiency
Conversion Efficiency is a key indicator with the best CIGS solar cells reaching 23%. This efficiency rate is crucial—greater efficiency means more energy harvested even under less-than-ideal lighting conditions, providing advantages for urban installations.
