CellAreaTotal
type: Class
EMMO 967080e5 2f42 4eb2 a3a9 c58143e835f9: The total cell area in cm2. The total area is defined as the area that would provide photovoltaic performance when illuminated without any shading, i.e. in practice the geometric overlap between the top and bottom contact.

SubstrateCleaning
type: Class
EMMO 967080e5 2f42 4eb2 a3a9 c58143e835f9: For the most common substrates, i.e. FTO and ITO it is common that part of the conductive layer is removed before perovskite deposition. State the method by which it was removed • If there is more than one cleaning step involved, separate the steps by a double forward angel bracket (‘ >> ‘) • This category was included after the initial project release wherefor the list of reported purities are short, so be prepared to expand on the given list of alternatives in the extraction protocol.

CellAreaMeasured
type: Class
EMMO 967080e5 2f42 4eb2 a3a9 c58143e835f9: The effective area of the cell during IV and stability measurements under illumination. If measured with a mask, this corresponds to the area of the hole in the mask. Otherwise this area is the same as the total cell area.

SemiTransparent
type: Class
EMMO 967080e5 2f42 4eb2 a3a9 c58143e835f9: Does not discriminate between different levels of transparency. In practice this is True for any cell that does not have metal contacts.
