Texturing for Heterojunction Silicon Solar Cells
Heterojunction solar cells have potential for very high device voltages and currents, yet this relies on correct preparation of wafer surfaces prior to a-Si deposition. This paper investigates the preparation of wafer surfaces by NaOH texturing prior to amorphous silicon intrinsic layer deposition. It is found that with a CP etch or low temperature anneal after texturing, and with correct depos...
متن کاملRIE-Texturing of Multicrystalline Silicon Solar Cells
We developed a maskless plasma texturing technique for multicrystalline silicon (mc-Si) cells using Reactive Ion Etching (RIE) that results in higher cell performance than that of standard untextured cells. Elimination of plasma damage has been achieved while keeping front reflectance to extremely low levels. Internal quantum efficiencies as high as those on planar cells have been obtained, boo...
متن کاملTexturing 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...
متن کاملSurface Texturing for Silicon Solar Cell Application Using Icp-pecvd Plasma Technique
This work is focused on plasma-induced texturing using a single chamber inductively coupled plasma – plasma-enhanced chemical vapour deposition (ICP-PECVD) lab-tool. Plasma treatment using pure NF3 under low pressure conditions leads to high etch rates (1.2–1.4 μm/min) enabling fast surface texturing. 6 min plasma treatment on wafers with saw damage decreases the effective reflectivity Reff fro...
متن کاملEffect of surface texturing by femtosecond laser on tantalum carbide ceramics for solar receiver applications
Tantalum carbide, as a Ultra-High Temperature Ceramic, is known to be characterized by intrinsic spectral selectivity, which makes it attractive for novel high-temperature thermal solar absorbers. However, a weakness point of TaC is the solar absorbance, which, in absence of any treatment, is usually lower than that of other materials currently under development for solar absorber applications....
