Fabrication of CuInSe2Absorber Layers for Thin Film Solar Cells by Doctor Blade Coating and Selenization using Solution Precursor

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...

Photolithography in Fabrication of Thin-film Solar Cells

Polymer solar cell by blade coating

Polymer bulk hetero-junction solar cells of poly(3-hexylthiophene) (P3HT) donor and (6,6)-phenyl-C61-butyric acid methyl ester (PCBM) acceptor are fabricated by blade coating in toluene solution. Desired donor–acceptor self-organization is achieved without the slow drying process and high boiling point solvent. Power conversion efficiency is 3.8%, much higher than the 2.6% obtained by spin coat...

SIGNIFICANCE OF SUBSTRATES AND BUFFER LAYERS IN CdTe THIN FILM SOLAR CELL FABRICATION

CdTe is considered as a viable absorber material for the thin film solar cell because of its excellent material characteristics as well as simple, low cost manufacturability. Despite a theoretical 29% efficiency prediction of the cell, its high work function and coefficient of thermal expansion (CTE) have limited its efficiency to around 17%. One of the remedies of the problem is using a pseudo...

Improving the optical properties of thin film plasmonic solar cells of InP absorber layer using nanowires

In this paper, a thin-film InP-based solar cell designed and simulated. The proposed InP solar cell has a periodic array of plasmonic back-reflector, which consists of a silver layer and two silver nanowires. The indium tin oxide (ITO) layer also utilized as an anti-reflection coating (ARC) layer on top. The design creates a light-trapping structure by using a plasmonic back-reflector and an an...
