Monolithic two-terminal tandem solar cells using Sb2S3 and solution-processed PbS quantum dots achieving an open-circuit potential beyond 1.1 V

, 2023
Multijunction solar cells show the prospect to raise the theoretical efficiency limit of single junction solar cells by minimizing transmissive losses of large bandgap and emissive losses of lower bandgap absorber solar cells. In solar cell applications,

Synthetic Surface Design of Transparent Electrodes for Enhanced Molecular Contact in Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
A simple solution‐based ITO surface treatment unlocks the full potential of phosphonic‐acid SAMs by balancing surface hydroxylation, conductivity, and homogeneity. Moderately hydroxylated interfaces yield uniform, electronically favourable contacts, enhancing charge extraction, stability, and thermal‐cycling resilience, with broad applicability across ...

Efficiency limits for single-junction and tandem solar cells

Basic limitations of single-junction and tandem p-n and p-i-n diodes are established from thermodynamical considerations on radiative recombination and semi-empirical considerations on the classical diode equations.

Zinc Sulfide Enabling Remarkable Surface Passivation of Crystalline Silicon

Advanced Energy Materials, EarlyView.
Polycrystalline ZnS films capped by Al2O3 provide outstanding surface passivation performance. The excellent lattice agreement between c‐Si and ZnS combined with a hydrogenation step result in extremely low interface state density (≈ 1×1010 cm−2 eV−1) and recombination current pre‐factor (1.0 fA/cm2), revealing a new passivation strategy for ...

Accelerated Formation of CsPbI3 through Controlled Amidation of Intermediate Phases

Advanced Energy Materials, EarlyView.
This study presents a reaction‐guided crystallization strategy for phase‐pure CsPbI3 thin films. In this strategy, the additive 2,2,2‐trifluoroethyl trifluoroacetate (TFTF) undergoes a rapid ester‐amine amidation reaction with dimethylammonium iodide (DMAI), converting both species into highly volatile byproducts that are eliminated during annealing ...
