Chesaux, Michael ; Howling, Alan A. A reactor using localized remote plasma in a grid electrode is presented in this study. The aim is to reduce the ion bombardment energy inherent in RF capacitively coupled parallel plate reactors used to deposit large area thin film silicon solar cells.
High ion bombardment energy could cause defects in silicon layers and deteriorate electrical interfaces, therefore, by reducing the ion bombardment energy, lower defect density might be obtained. In this study, the low ion bombardment energy results from the reactor design.
By inserting a grounded grid close to the RF electrode of a parallel plate reactor, the electrode area asymmetry is increased while retaining the lateral uniformity required for large area deposition.
This asymmetry causes a strong negative self-bias voltage, which reduces the time-averaged plasma potential and thus lowers the ion bombardment energy. None of these blocks can be placed on the edge or corner; they must be somewhere in the faces of the reactor, sometimes in very specific places. Right clicking on the reactor casing or turbine housing will display a message of what is missing.
Important: Ensure that there aren't any metallic blocks within a 1 block radius of the turbine! Doing so results in unpredictable behavior with the turbine. Download this spreadsheet to calculate the required materials and their cost for any size Reactor structure.
Use this Big Reactor Simulator to test the efficiency of different Reactor designs. All reactors must have exactly one Reactor Controller block, which provides the main interface for monitoring the status of the reactor. Access Ports are buffers that contain unused fuel and waste. An active reactor will use the fuel from the 'Inlet' port and dump waste into the 'Outlet' port. A Big Reactor needs at least one access port.
The core of the reactor is an arrangement of Yellorium Fuel Rods. These must be stacked to stretch the entire interior height of the reactor. The entire volume of the reactor may be filled with fuel rods, but it does not have to be. The Reactor will usually be more efficient with the Fuel Rods placed diagonally in a checker board pattern with a coolant filling the gaps.
It also tells the reactor where the fuel rods are so it can fill them with fuel. Reactors that provide RF energy directly need to have at least one Reactor Power Tap as part of the structure.
Coolant Ports allow fluids to be injected into and steam drained from the reactor to be transported to feed a turbine. The fuel inside the fuel rods generates power, radiation and heat.
Heat is transferred to the adjacent 4 blocks from the fuel rods into a coolant or fuel rod block, and likewise radiation is transferred up to 4 blocks dependant on adjacent block absorption in the cardinal directions North,South,East,West. Excess radiation and heat could cause the temperature in the reactor to rise above efficient levels and consume more fuel, since there is a penalty to fuel consumption at too high an operating temperature.
A coolant reduces the temperature of a reactor, and moves heat from the reactor core to the reactor casing. The higher the casing heat, the higher the energy output and heat transfer rate of coolants [1].
Any fluid used as coolant must be manually added to the reactor during construction, exactly as you would with solid coolant materials. Those looking to fill large reactors with fluids that fall, such as Gelid Cryotheum , may want to consider using a Flood Gate of Fluid Outlet.
Each coolant material has various parameters that govern how it affects the reactor [2] :. A Turbine produces energy from Steam generated by an active cooling Reactor or generated using one of 6 other mods methods. Try again? Cited by.
