6 FAQs about [Superposition of perovskite solar cells]
Can thermal evaporation be used to make perovskite solar cells?
The development of perovskite photovoltaics has so far been led by solution-based coating techniques, such as spin-coating. However, there has been an increasing interest in thermal evaporation (TE) as an industrially compatible method to fabricate perovskite solar cells (PSCs).
What is the superposition principle in photovoltaics?
The concept of Equation (2) is known in photovoltaics as the superposition principle. Similar to the SQ model of the maximum efficiency, the superposition principle derives its value not from its applicability to real solar cells but instead from the deviations from this principle that are present in nearly every practical solar cell.
Why are perovskite-based photovoltaics becoming popular?
Perovskite-based photovoltaics have attracted increasing research and industry interest owing to their abundant raw material, low-cost, high performance, and flexibility. After the rapid development of lab-scale perovskite solar cells (PSCs), there is a huge demand to promote their fab-scale manufacturing.
Why is up-scaling of perovskite solar cells important?
Up-scaling of perovskite solar cells to perovskite solar cells large-scale perovskite solar modules is essential to further promote the lab-to-fab development of perovskite-based photovoltaics.
What is the fill factor of a perovskite solar cell?
Given that the fill factor was 84.0% (exceptionally high for perovskite solar cell) and FF 0 (n id = 1.26, V oc = 1.15 V) = 87.4%, there must have been a substantial resistive contribution to the fill factor in these cells that is not explicitly included in Figure 1a.
What is series resitance of a perovskite solar cell?
For a practical perovskite solar cell, the total series resistance has ohmic and nonohmic contributions, and hence also the series resitance measured using the three Equation (5), (9), and (10) will be voltage (or current) dependent.
