Technical FAQs 4

Why does PERC solar cell efficiency decrease over time?

Its efficiency decreases over time because of the Light-Induced degradation (LID) that follows countless hours of exposure to light (above 50 o C temperature), and collectively is termed as Light and Elevated Temperature Induced Degradation (LeTID). Every PERC solar cell module experiences the LeTID effect significantly.

What is light-induced degradation (lid) of MC-PERC solar cells?

light-induced degradation (LID) of mc-PERC solar cells has been reported to cause efficiency losses of up to 10%rel. This highlights the importance o of solar cells under actual operating conditions.Market WatchIntroduction: PERC technology enters mass productionThe passivated emitter and rear cell (PERC) is one cell tec

Is PID a degradation mechanism in PERC solar cells?

A long-term PID evolution up to 672 h is performed for glass/back sheet PERC cell modules. The substantial drop in R sh and FF together with dark I-V data suggest that the PID-s is the degradation mechanism occurring at the emitter side of PERC solar cells.

How efficient are PERC solar modules?

An impressive efficiency of 23.52% has been achieved on mass production line. The optimized PERC solar modules show excellent PID resistance, showing great potential for lower levelized cost of energy (LCOE) of photovoltaic power generation.
