52mm x 52mm 0.62W Bifacial PERC Solar Cells
Compact Bifacial PERC Cell Overview
These 52mm x 52mm 0.62W bifacial PERC solar cells are A-grade monocrystalline photovoltaic components for compatible compact module layouts, prototypes, and DIY solar projects. Choose a 20-, 50-, or 100-piece cells-only pack to match the scale of the planned assembly.
Key Features for Small Module Builds
- Bifacial PERC construction: active front and rear surfaces support module designs that account for light reaching both sides of the cell.
- Compact square format: the 52mm x 52mm dimensions help builders plan small-area cell matrices and custom layouts.
- 0.62W at 0.6V per cell: the confirmed electrical values support early series-string and module calculations.
- Front and rear efficiency figures: front-side efficiency is 23.2%, with 15.5% specified for the rear side.
- Cells-only quantities: current options contain solar cells without tabbing wire, flux, or soldering tools.

Handling and Module Planning
Bare cells are fragile. Keep them flat, avoid bending and point loads, and protect the active surfaces and conductors from contamination. Confirm polarity, conductor dimensions, series-string voltage, spacing, encapsulation, rear-side optical access, insulation, and lamination conditions for the intended module design. Actual finished-module output depends on irradiance, temperature, cell matching, electrical layout, interconnection losses, and assembly quality.
