Abstract
Indoor photovoltaics (IPVs) exhibit performance instability under nonuniform indoor lighting due to current mismatch losses. This study proposes a current-density mapping protocol that integrates EQE data with spatial light distributions to identify optimal small-area, high-voltage (SAHiV) configurations. Analysis reveals that dividing a 100 cm² module into nine subcells minimizes resistive and mismatch losses across illuminance levels (500–100,000 lx). J-maps generated from polynomial distortions classify designs into three symmetry groups—linear, rotational, and transition—providing practical guidelines for environment-specific module layouts. Extending this 2D approach to 3D architectures is proposed to enhance stability under dynamic lighting conditions.
