Most industrial crystalline silicon solar cells suffer from some type of light-induced degradation (LID). This review compiles all known properties of boron-oxygen LID and copper-related LID, together with the latest LID results in quasi-mono and multicrystalline silicon.
This review article examines the current state of understanding in how metal halide perovskite solar cells can degrade when exposed to moisture, oxygen, heat, light, mechanical stress, and reverse bias.
Despite the notable progress in PCE over the past decade, the inherent high defect density presenting in perovskite materials gives rise to several loss mechanisms and associated ion migration in perovskite solar cells (PSCs) during operational conditions.
Perovskite solar cells degrade quickly under natural day/night cycling, compared with continuous illumination, owing to periodic lattice strain during cycling; the lattice strain can be regulated by adding phenylselenenyl chloride.
1. Introduction Light-induced degradation (LID) refers to a loss in the silicon solar cell efficiency that is observed during excess carrier injection by above-bandgap illumination or forward biasing .
These data suggest that degradation related to B-O defects is fully recoverable in a cell (about 0.4% absolute in cell efficiency), whereas surface degradation (about 0.1% of cell efficiency) is not recovered. Interestingly, a partial recovery of the surface-phenomenon-related effect occurs if the light soaking is not complete. II.
