Equitable revenue allocation in DEA under a common set of weights: a unified optimization approach

Data Envelopment Analysis (DEA) can be used to allocate common revenue. This paper proposes a common revenue allocation approach based on a common set of weights (CSW). The proposed approach is governed by two principles: efficiency ratio (ER) invariance and common weight ratio (...

Boosting Open‐Circuit Voltage to a Record 0.692 V in Solution‐Processed CIGSSe Solar Cells Through Surface Ga‐Rich Engineering

ABSTRACT The open‐circuit voltage ( V OC ) deficit remains a primary bottleneck hindering the efficiency of solution‐processed Cu(In,Ga)(S,Se) 2 (CIGSSe) solar cells, largely due to the uncontrolled elemental diffusion during high‐temperature selenization that prevents the format...
