Emergency medical services (EMS) often serve as the first medical contact for ill or injured patients, representing a critical access point to the health care delivery continuum. While a growing body of literature suggests inequities in care within h

Window and buffer layers in chalcopyrite devices are well known to affect junctions, conduction, and photo-absorption properties of the device. Some of these layers, particularly “buffers,” which are deposited directly on top of the absorber, exh

Cu(In,Ga)Se2 (CIGS) photovoltaic absorbers frequently develop Ga gradients during growth. These gradients vary as a function of growth recipe, and are important to device performance. Prediction of Ga profiles using classic diffusion equations is not

We studied a variety of absorber thicknesses in Cu(In,Ga)Se 2 devices to examine the ability of the cell to withstand reverse current flow without damage. Absorbers were varied from 2.5 µm to 0.4 µm, with the expectation that larger reverse current

Modifications to the buffer structure in Cu(In,Ga)Se2 (CIGS) solar cells are examined in terms of power conversion efficiency and metastability. Varying amounts of thin hole-injecting layers are introduced at different locations in the CIGS/Zn(O,S) d

In this study, we incorporated Sb into the precursor that was subsequently converted to Cu(In,Ga)Se2 (CIGS) by a selenization process. We observed enhanced grain size and improved device performance compared with similarly processed CIGS films made w

Cu(In,Ga)Se2 (CIGS) solar cells fabricated with two-step selenization processes commonly suffer from low open-circuit voltage ( $V_{{\bf oc}}$ ). We found that the $V_{{\bf oc}}$ of solar cells made from selenized Cu/Ga/In stacked metal precursors ca

The Design of Experiments (DoE) module in JMP statistical software was used to determine the best parameters for Sb-containing CIGS precursors with a fixed selenization step. Solar cells were fabricated and measured for all completed films. The most
