12th Euregional Workshop on Novel Concepts for Future Thin-Film Silicon Solar Cells

Design of Silicon Nano-Bars Anti-Reflection Coating to Enhance Thin Film Solar Cells Efficiency

In this paper a novel anti-reflection (AR) coating based on silicon nano-bars is designed and its impact on the performance of crystalline silicon (c-Si) thin-film solar cells is extensively studied. Silicon nano-bars with optimized size and period are embedded on top of the active layer, under a 100nm Si3N4 layer. As a result of the proposed layer stack, an inhomogeneous intermediate layer wit...

Novel Deposition Technique for Fast Growth of Hydrogenated Microcrystalline Silicon Thin-Film for Thin-Film Silicon Solar Cells

Excitation of plasmon and guided-mode resonances in thin film silicon solar cells

Thin film silicon solar cells are an attractive option for the production of sustainable energy but their low response at long wavelengths requires additional measures for absorption enhancement. The most successful concepts are based on light scattering interface textures whose understanding is greatly facilitated by considering a superposition of periodic textures that diffract the light into...

Amorphous solar cells, the micromorph concept and the role of VHF-GD deposition technique

During the last two decades, the Institute of Microtechnology (IMT) has contributed in two important fields to future thin-film silicon solar cell processing and design: (1) In 1987, IMT introduced the so-called ‘‘very high frequency glow discharge (VHF-GD)’’ technique, a method that leads to a considerable enhancement in the deposition rate of amorphous and microcrystalline silicon layers. As ...

Probing the Nature of Annealing Silicon Carbide Samples for Solar Cell

SiC powder preparation using Sol-Gel method. The size of nano-particles grows as the temperature exceeds 900° C. Size of probable agglomerations produced, is approximately less than 50nm. The surface is suitable to be used for dye solar cells. SiC emission occurs at wavelength area of 11.3μm or wave number area of 884.95 cm-1. In this paper probing the nature of annealed SiC samples in mixture,...
