Development of bifacial n-type solar cells for industrial application

OPTIMISATION OF p + DOPING LEVEL OF n + - p - p + BIFACIAL B . S . F . SOLAR CELLS BY ION IMPLANTATION

be a region of uncertainty near the centre of the cable. Further improvements are still possible. Cooling a photo-diode or decreasing its physical size reduces the leakage current and thus permits a higher bias voltage. This has two important consequences. Firstly, it increases the detection probability almost to the quantum efficiency of the diode, and secondly, it eases optical alignment prob...

COMPARISON OF BIFACIAL AND MONOFACIAL LARGE-AREA n-TYPE SI SOLAR CELLS FROM 100 μm THIN WIRE-SAWN WAFERS

Reducing wafer thickness provides the most effective potential to lower the production cost of c-Si PV modules. Two thin n-type solar cell concepts are compared in terms of their optical and electrical properties: a monofacial device with a full-area metal surface at the rear which is beneficial in particular to such thin solar cells and a very similar but even better industrially applicable bi...

Contact Formation on P-doped Si by Screen-printing Pure Ag Pastes for Bifacial N-type Si Solar Cells

n-type solar cell concepts increasingly utilize emitter formation by diffusion from boron doped sources. Combining the advantage of n-type silicon material and bifacial cell architecture enables high-efficiency and versatile photovoltaics. In case of boron emitters, it was standard until now to form a metal-semiconductor contact by screenprinting Al containing Ag pastes. Instead of utilizing Al...

Texturing industrial multicrystalline silicon solar cells

Three potential techniques for texturing commercial multicrystalline silicon solar cells are compared on the basis of reflectance measurements. Wet acidic texturing, which would be the least costly to implement, produces a modest improvement in reflection before antireflection coating and encapsulation, whereas maskless reactive-ion etching texturing, and especially masked reactive-ion etched p...
