Diffusion bonding cycle times can be a large cost factor in the production of metal microchannel devices. The challenge is to significantly minimize this cost by reducing the bonding cycle time through rapid and uniform heating and cooling within the bonding process. Heating rates in diffusion bonding processes are typically...
An alumina microreactor was designed and fabricated to study the synthesis of nanosized silicon nitride powder via the ammonolysis of SiO vapor at temperatures ranging from 1300°C to 1400°C. It is the first high temperature ceramic microreactor capable of operating at temperatures upto 1600°C. The microreactor was designed using 3D...
Solution deposition offers an attractive, low temperature option in the cost effective production of thin film solar cells. Continuous microreactor-assisted solution deposition (MASD) was used to produce nanocrystalline cadmium sulfide (CdS) films on fluorine doped tin oxide (FTO) coated glass substrates with excellent uniformity. We report a novel liquid coating...
Cadmium sulfide (CdS) thin films are commonly used as buffer layers in thin film solar cells and can be produced by a number of solution and vacuum methods. We report the continuous solution deposition of CdS on fluorine-doped tin oxide coated glass substrates using Microreactor-Assisted Solution Deposition (MASD (TM)). A...
Photovoltaic cells have long been a desirable alternative to the consumption of fossil fuels, but current manufacturing practices suffer from poor energy efficiency, large carbon footprints, low material utilization, and high processing temperatures. A critical step in production of thin film CdTe and CuInSe₂ solar cells is the chemical bath...
