6 FAQs about [Reasons for low light decay of n-type cells]
Does light-induced degradation occur in commercial n-type silicon heterojunction solar cells?
In this paper, we study a light-induced degradation (LID) mechanism observed in commercial n-type silicon heterojunction (SHJ) solar cells at elevated temperatures using dark- and illuminated annealing for a broad range of illumination intensities (1–40 kWm −2) at temperatures from 25 to 180 °C. Three key results are identified.
Do light-induced defects in n-type SHJ cells depend on temperature and illumination intensity?
While the mechanisms underlying this thermally-activated, light-induced defect in n-type SHJ cells remain uncertain, the above results provide some insight through the dependence of degradation and recovery kinetics on temperature and illumination intensity.
Do SHJ solar cells have a low power loss?
Additionally, SHJ cells are perceived to have a reduced susceptibility to light-induced degradation (LID) , the most widely studied degradation mechanism in solar cells, and thus experience lower relative power losses during long-term operation in-field.
Why are solar cell performance at low light intensity important?
On the contrary, the solar cell performances at low light intensity such as cloudy weather, early mornings, or late afternoon are practically important forpower generation capacity in the entire life cycle.
What is light- and elevated temperature-induced degradation (letid)?
More recently, in conventional p-type silicon solar cells, a new LID mechanism called light- and elevated temperature-induced degradation (LeTID) was identified, capable of causing a loss in η of up to 16% relative in multi-crystalline silicon cells under illumination [, , , ].
What determines TRPL decay at low fluences?
The authors predicted that the TRPL decay at low fluences is determined by the rapid extraction of photogenerated electrons to the PCBM layer at early times while interfacial recombination dominates the decay at latter times, as shown in Figure 8.
