“…The primary challenges associated with screen‐printed CZ bifacial solar cells are the BBr 3 boron diffusion, boron‐diffused surface passivation, and metallization. It is known that junction depth, surface carrier concentration, sheet resistance, and diffusion uniformity control the dark saturation current density J 0 and the effective lifetime in silicon solar cells 10. As part of this work boron diffusion conditions have been tailored in order to achieve critical cell physical parameters necessary for bifacial operation.…”

We present industrialized bifacial solar cells on large area (149 cm2) 2 cm CZ monocrystalline silicon wafers processed with industrially relevant techniques such as liquid source BBr3 and POCl3 open‐tube furnace diffusions, plasma enhanced chemical vapor deposition (PECVD) SiNx deposition, and screen printed contacts. The fundamental analysis of the paste using at boron‐diffused surface and the bifacial solar cell firing cycle has been investigated. The resulting solar cells have front and rear efficiencies of 16.6 and 12.8%, respectively. The ratio of the rear JSC to front JSC is 76.8%. It increases the bifacial power by 15.4% over a conventional solar cell at 20% of 1‐sun rear illumination, which equals to the power of a conventional solar cell with 19.2% efficiency. We also present a bifacial glass–glass photovoltaic (PV) module with 30 bifacial cells with the electrical characteristics. Copyright © 2010 John Wiley & Sons, Ltd.

“…Accurate measurements of transport properties are therefore a major issue that still requires some improvements. In particular, the minority carrier diffusion length is one of the most important parameters affecting the solar cell performance that can be evaluated by light beam induced current (LBIC) and electron beam induced current (EBIC) in starting materials [5,6], or from internal quantum efficiency (IQE) [7][8][9] and I-V [10,11] silicon layers deposited on 2 in. substrates has permitted the fabrication of solar cells with a conversion efficiency Á = 9.5% [12].…”

“…At all wavelengths, the Voc decreased at the rate of 1.79 mV/℃. As the temperature rise, the intrinsic carrier density in the light absorption layer increase which resulted in excessive recombination current densities, and it may have led to a drop in the Voc [27][28][29]. As it can be seen that the Isc is almost independent on temperature.…”

Power generation characteristics of a Si PV cell under extremely high optical power near-infrared irradiation were investigated for use in optical wireless power transmission. We used high power LED light sources with 730 nm, 850 nm and 940 nm wavelengths and a condensing optics to realize 10-sun level extremely high optical power irradiation in the measurements. More than 0.22 W electrical power was generated from a 1 cm square Si heterojunction PV cell under about 1 W/cm² optical power irradiation. This is more than 10 times the power generation density of conventional Si solar panels. Estimated power conversion efficiencies under 10-sun power level near-infrared irradiation exceeded 22.5%, which indicate a potential for high-power wireless transmission with Si PV cells using near-infrared light.
