3D study of a Polycrystalline Bifacial Silicon Solar Cell, Illuminated Simultaneously by Both Sides: Grain Size and Recombination Velocity Influence

In this work, for simultaneous illumination of both sides of the polycrystalline bifacial silicon solar cell, we study the influence of grain size and recombination velocity at grain boundaries, on the macroscopic and microscopic parameters. The study allows us understandind why the carrier density, current density and photovoltage have lower values than those collected on the monocrystalline Si when the solar cell is illuminated simultaneously by both sides. It highlighted the electrical parameters degradation of the solar cell as photocurrent, short-circuit current, photovoltage and open circuit voltage, when grain size decreases or when recombinations at grain boundaries are high.
