Doped surfaces in one sun, point-contact solar cells
TLDR
In this paper, two new types of large-area (>8.5 cm2), backside, point-contact solar cells with doped surfaces, designed for use in unconcentrated sunlight, were reported.Abstract:
This letter reports two new types of large‐area (>8.5 cm2), backside, point‐contact solar cells with doped surfaces, designed for use in unconcentrated sunlight. One type was fabricated on an intrinsic substrate with an optimized phosphorus diffusion on the sunward surface. The apertured‐area efficiency was independently measured to be 22.3% at 1 sun (0.100 W/cm2), 25 °C, the highest reported for a silicon solar cell. The other type is constructed on a doped substrate, and has an apertured‐area efficiency of 20.9%, the highest reported for a point‐contact solar cell with a base in low‐level injection. Both cells have record open‐circuit voltages above 700 mV.read more

Design criteria for Si point-contact concentrator solar cells
TL;DR: In this paper, design criteria for concentrator solar cells are presented for the highly three-dimensional case of backside point-contact solar cells and the optimum geometry is found to depend upon the intended design power density as well as the attainable physical parameters allowed by the fabrication techniques utilized.
