4 Frequently Asked Questions about "Are there GBS on photovoltaic panels "

Do interaggregate grain boundaries affect photovoltaic performance of perovskite solar cells (PSCs)?

There exists a considerable density of interaggregate grain boundaries (GBs) and intra-aggregate GBs in polycrystalline perovskites. Mitigation of intra-aggregate GBs is equally notable to that of interaggregate GBs as intra-aggregate GBs can also cause detrimental effects on the photovoltaic performances of perovskite solar cells (PSCs).

What is the significance of GBS in polycrystalline semiconductors for solar applications?

The significance of GBs in polycrystalline semiconductors for solar applications remains elusive due to varying reports, making research on GBs essential . The absorber material in photovoltaic SCs, polycrystalline lead halide perovskite, exhibits several advantageous optical and electrical characteristics.

Do interaggregate GBS affect photovoltaic performance?

Previous studies mainly concerned the interaggregate GBs as they may adversely affect the charge carrier transport, facilitate ion migration, and even produce some deep sub-band energy levels within the bandgap (16, 17), leading to major nonradiative losses that limit the photovoltaic performance (13, 18, 19).

Do perovskite solar cells have grain aggregates and intra-aggregate GBS?

Recently, the existence of grain aggregates and intra-aggregate GBs has been confirmed by electron backscatter diffraction and TEM (27 – 31). Li et al. (29) and Cai et al. (30) start to correlate the performances of perovskite solar cells (PSCs) with the density and structure of intra-aggregate GBs in polycrystalline perovskite films.
