On the Interplay Between Microstructure and Interfaces in High-Efficiency Microcrystalline Silicon Solar Cells [PDF]

, 2012
This paper gives new insights into the role of both the microstructure and the interfaces in microcrystalline silicon (μc- Si) single-junction solar cells. A 3-D tomographic reconstruction of a μc-Si solar cell reveals the 2-D nature of the porous zones,

Superimposed Sacrificial Texturing to Enhance the Optical Performance in Thin‐Film Solar Cells

Progress in Photovoltaics: Research and Applications, EarlyView.
Sacrificial texturing method using controlled etching of undoped zinc oxide and indium‐doped tin oxide generates microscale and nanoscale textures on glass. Roughness on two different scales is superimposed to create a new texture capable of broad‐spectrum scattering, which is utilised in thin‐film silicon solar cells to enhance optical performance ...

Discovery of Sustainable Energy Materials Via the Machine‐Learned Material Space

Small, EarlyView.
State‐of‐the‐art machine learning models used in materials science are shown to construct meaningful internal representations, which can be interpreted as a map of the material space from the viewpoint of the network. It shows how this map can be used to find alternative, e.g., more sustainable materials for important optical materials, such as ...

Influence of the Chemical Composition on the Perovskites Anharmonicity: Toward a Stable Inorganic Perovskite

Solar RRL, EarlyView.
This study investigates the effect of the chemical composition on the properties of A(BB’)(XX’)3$_3$ inorganic halide perovskites with density functional theory. By correlating distortion amplitudes with both composition and the Goldschmidt tolerance factor, we propose a pragmatic approach to designing more stable and efficient perovskites, advancing ...

Fast and Simple Series Resistance Imaging for Tandem Solar Cells Using Differential Luminescence

Solar RRL, EarlyView.
This article presents a method for imaging the series resistance of subcells in a multijunction device. It requires few input properties, no current or voltage calibration and only three measured images. Validated on single junction and multijunction perovskite‐based devices, this method provides a practical tool for advancing photovoltaic research and
