Abstract
The sun bathes our planet with far more energy than humankind will possibly ever need (> 8,000 times the current demand). Yet, sustainable energy provision is among the most pressing challenges faced today. In order to unlock the vast potential of clean solar energy, we need disruptive technologies capable of efficiently harvesting sunlight, while being deployable at unprecedented scales. Available commercial photovoltaics (PV) can hardly cope sustainably with the sheer scale of this challenge. Silicon solar panels are the major commercial PV, they are based on a very Earth-abundant element, but their fabrication is extremely energy intensive. Conversely, thin film solar panels based on CdTe and Cu(In,Ga)Se2 (CIGS) require far less energy to produce, but some of their constituent elements are quite rare on the Earth’s crust. Hence, in both cases, the short term economic and ecologic sustainabilities are dubious. Recently, an advanced PV concept, called microconcentrator PV [1], has been conceived, which is free from raw materials availability constraints and is based on sunlight absorbers requiring low energy to grow. Additionally, semi-transparent panels could be created, consisting of stripes having width on the order of 100 micrometers [2]. To demonstrate such advanced PV concepts at laboratory scale, research groups have been using optical projection lithography (OPL), generating arrays of Cu(In,Ga)Se2 circles with tens of micrometer diameter. However, OPL cannot be scaled credibly to terawatt deployment. Industrial uptake of microconcentrator PV is only possible with a technique that ensures both high semiconductor quality, and high throughput at capital expenditure comparable to or lower than currently available PVs. Inspired by the research of Gary Friedman on ferrofluid lithography [3], a disrupting microfabrication technique is being pursued within REMAP [5], and e-APP projects [6]. Our intent is to pioneer a method that could be scaled economically to deploy terawatts of microconcentrator or semi-transparent PV [4]. Herein, we outline the progress made on the formulation of magnetorheological electrolytes: bifunctional fluids intended for effective reusable masking, from synthesis to application.
