The study of grain boundaries in polycrystalline thin-film solar cells

In order to investigate the interplay between grain boundary and intra-grain defects on solar cell performance and determine the potential benefits of developing biaxially-textured film solar cells, I

Grain Boundaries Contribute to the Performance of Perovskite Solar

Historically seen as a limitation, grain boundaries (GBs) within polycrystalline metal halide perovskite (MHP) films are thought to impede charge transport, adversely impacting the

Cementitious grain-boundary passivation for flexible perovskite solar

The power conversion effciency (PCE) of flexible perovskite solar cells (PSCs) has increased rapidly, while the mechanical flexibility and environmental stability are still far from satisfactory. Previous

Grain boundar strain locali ation in CdTe solar cell revealed b

Abstract Cadmium Telluride (CdTe) solar cell technology is a promising candidate to help boost green energy production. However, impurities and structural defects are major barriers to improving the

Consequences of grain boundary barriers on electrical characteristics

The model assumptions and simulation results show how the concentration of surface donors at the grain boundaries affects the height of the grain boundary barriers and the measured

Role of Grain Boundaries | part of Hybrid Perovskite Solar Cells

Grain boundaries (GBs) in polycrystalline halide perovskite solar cells play a significant role in not only device performance but also stability. The first section of this chapter (Section ) provides fundamental

Machine learning quantification of grain boundary defects for high

The power conversion efficiency of perovskite solar cells has been significantly improved in recent years. One of the key factors leading to this change is that the microstructure of

The impact of grain boundary defects on the current-voltage

The work presents two-dimensional simulations of the impact of donor defects at grain boundaries (GB) on potential barriers at the GBs in Cu (In,Ga)Se 2 (CIGS) thin films as well as on the

杨阵海、曹国洋等在Energy & Environmental Science发表论文

Abstract: Grain boundaries (GBs), inherent in polycrystalline perovskite films and associated with numerous trap states, are widely regarded as non-radiative recombination centers

Grain-boundary grooves in perovskite solar cells

Abstract As a general materials phenomenon driven by thermodynamics, grain boundary network, when extending onto the film surface or interface, can create an intriguing grooving geometry. Such formed

Chemical passivation and grain-boundary manipulation via in situ

The resulting perovskite film exhibited higher crystallinity, enlarged grain size, and reduced dependence on the substrate. In addition, the cross-linked FTA [CL (FTA)] distributed along the grain boundaries

Grain Boundaries Contribute to the Performance of Perovskite Solar

Sub-micrometer-resolved photocurrent mapping in operational perovskite solar cells, achieved through our home-built photoluminescence and photocurrent imaging microscopy, reveals

Stabilizing Grain Boundaries by In Situ Formation of Robust Layered

The grain boundaries (GBs) instability induced by photodecomposition of residual PbI2 is long-standing challenge for further simultaneous improvement of stability and power conversion

Review of grain interior, grain boundary, and interface effects of K in

This review addresses the question of how K boosts performance. Early studies of K in CIGS assumed it was similar to Na—primarily modifying grain interior (GI) and grain boundary (GB)

Recombination velocities at grain boundaries in solar-cell absorbers

Since the (two-dimensional, projected) density of point defects at a grain-boundary plane is enhanced with respect to those (three-dimensional) in the grain interiors of the adjacent grains, the nonradiative

Revealing Different Types of Grain Boundaries in Perovskite Films by

Grain boundaries (GBs) in polycrystalline perovskite films play a crucial role in determining photogenerated carrier transport and recombination, thereby impacting both efficiency
