MNRE said the existing ALMM List-II contains cell model names submitted by individual manufacturers, with no prescribed nomenclature. Manufacturers have therefore used their own naming conventions, resulting in variations that do not provide a uniform basis for identifying the technical characteristics of cells.
Under the proposed system, the first four positions of the code would identify the origin of polysilicon, ingot, wafer, and cell, respectively. ‘D’ would indicate domestic Indian origin and ‘F’ foreign origin.
The fourth position would identify the origin of the cell itself. MNRE has specified that a solar cell manufactured in India using a blue wafer, or diffused silicon wafer, would not be treated as a domestically manufactured cell.
The next two positions would identify cell technology. The proposed codes are MP for monocrystalline passivated emitter and rear contact (PERC), TC for tunnel oxide passivated contact (TOPCon), HJ for heterojunction technology (HJT), BC for back contact and PS for perovskite.
Positions seven and eight would identify wafer size, with MA representing M10, MB for M10R, GA representing G12 and GB for G12R.
Positions nine to 11 would represent cell efficiency, with the decimal point omitted. A cell with an efficiency of 24.67% would therefore be represented as 246, while a 25.55% cell would be represented as 255. The final three positions would remain reserved.
For example, MNRE said ABC FDDDTCGB256xxx would represent a cell manufactured by brand ABC using foreign polysilicon, domestic ingot and wafer, and a domestically manufactured cell. 67%.
