“…Methods that focus on increasing throughput (and thereby reducing $/m 2 ) are prone to sacrificing quality, with lower bulk lifetimes caused by increased structural defect densities resulting from large thermal gradients during growth. The reduction in material quality impacts cell efficiency, which is kept lower than that achieved by industry‐standard Cz‐Si and mc‐Si; ribbon c‐Si solar cell efficiencies, for example, have plateaued at ~18% with sophisticated laboratory‐scale processing , while staying in the 13–16% range at the industrial level . Thus, the throughput‐efficiency trade‐off of these alternative methods has turned out unfavorable so far because the efficiency cost penalty is severe , resulting in higher $/W.…”

Silicon wafers comprise approximately 40% of crystalline silicon module cost and represent an area of great technological innovation potential. Paradoxically, unconventional wafer-growth techniques have thus far failed to displace multicrystalline and Czochralski silicon, despite four decades of innovation. One of the shortcomings of most unconventional materials has been a persistent carrier lifetime deficit in comparison to established wafer technologies, which limits the device efficiency potential. In this perspective article, we review a defect-management framework that has proven successful in enabling millisecond lifetimes in kerfless and cast materials. Control of dislocations and slowly diffusing metal point defects during growth, coupled to effective control of fast-diffusing species during cell processing, is critical to enable high cell efficiencies. To accelerate the pace of novel wafer development, we discuss approaches to rapidly evaluate the device efficiency potential of unconventional wafers from injection-dependent lifetime measurements.

“…Solar energy and photovoltaics are becoming an increasingly important part of the electrical power generation mix. Essential to reducing the costs of this energy source is the reduction in the cost of photovoltaic modules, many methods to accomplish this are being pursued such as alternative deposition methods for conventionally used silicon photovoltaic materials [1,2] and entirely new photovoltaic materials such as cadmium telluride, copper indium gallium selenide, copper zinc tin sulfide [3], organic photovoltaic materials [4] and perovskites. Perovskite photovoltaics have rapidly become the subject of intense research efforts due to their unique properties of potentially low materials costs [5,6,7], suitability for solution processing [8], intriguing device physics [9,10,11] and astonishingly high efficiencies [12,13].…”

Sequential Slot-Die Deposition of Perovskite Solar Cells Using Dimethylsulfoxide Lead Iodide Ink

et al. 2018

This work demonstrates a sequential deposition of lead iodide followed by methylammonium iodide using the industrially compatible slot-die coating method that produces homogeneous pin-hole free films without the use of the highly toxic dimethylformamide. This is achieved through the careful selection and formulation of the solvent system and coating conditions for both the lead iodide layer and the methylammonium iodide coating. The solvent system choice is found to be critical to achieving good coating quality, conversion to the final perovskite and for the film morphology formed. A range of alcohols are assessed as solvent for methylammonium iodide formulations for use in slot-die coating. A dimethylsulfoxide solvent system for the lead iodide layer is shown which is significantly less toxic than the dimethylformamide solvent system commonly used for lead iodide deposition, which could find utility in high throughput manufacture of perovskite solar cells.
