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...

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...

n-type black silicon solar cells

Black silicon is an interesting surface texture for solar cells because of its extremely low reflectance on a wide wavelength range and acceptance angle. In this paper we present how black silicon (b-Si) texturization can be applied on the boron doped front surface of an n-type solar cell resulting in an efficiency of 18.7 %. We show that the highly boron doped emitter can be formed on black si...

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...
