While the analysis of optical gains and power transfer of monofacial photovoltaics module are relatively well established, there are many nuanced effects that contribute to bifacial cell to module power transfer. To improve the bifacial module power during indoor flash test, reflective layers had been included in the inter-cell spacing. This reflective layer improves bifacial module STC maximum power point (Pmpp) and current. This paper presents the investigation and analysis of bifacial PV modules with reflective layer at the inter-cell spacing. Three main bifacial module configurations with reflective layer are studied where the reflective surface was inserted at different positions, (1) behind the rear glass or transparent back sheet, (2) in between the glass and encapsulant, and (3) in between the encapsulant. A numerical model is created to simulate the current gain from each configuration with varying inter-cell spacing with varying illumination positions.
