Tools for Slot-die Coating
Wet Thickness Calculator
A simple spreadsheet that works out how thick a coating is when it has just been applied, before it dries. You enter the pump flow rate, the coating width and the web speed. It calculates t_wet = Q × 1000 / (W × v).
Dry Thickness Calculator
A simple spreadsheet that works out how thick a coating will be once it has dried. You enter the wet thickness, how much solid material is in the solution, and the density and porosity of the dried film. It calculates t_dry = t_wet × c / [1000 × ρ_film × (1 − φ)].
Coating Length Calculator
Use this calculator before a slot-die run to check whether you have enough ink for the length you want to coat. Enter the ink volume, dead volume, flow rate, coating width and web speed, and it calculates the coating length or how much ink you need for a target length.
Tools for Solar Cells Measurements
Power Conversion Efficiency Calculator
Use this calculator to find the power conversion efficiency (PCE) of a lab-scale solar cell straight from its J–V measurement. Enter the short-circuit current, Voc, fill factor and active area and it calculates the PCE.
