Contact-printed ultrathin siloxane passivation layer for high-performance Si-PEDOT:PSS hybrid solar cells

Stretchable, Bifacial Si-Organic Hybrid Solar Cells by Vertical Array of Si Micropillars Embedded into Elastomeric Substrates

“…The front cell shows a conversion efficiency of ∼3.3%, whereas the rear cell has an efficiency of ∼1.7%, leading to bifaciality factor (η) of ∼50%. The rather low cell efficiency for front cell is mainly due to low short circuit current ( J sc ) and fill factor (FF), compared with Si-organic hybrid solar cells fabricated on planar Si substrate reported in literature. , The small aerial coverage of Si (∼20%) is responsible for the small J sc , while better electrical contact and electrode sheet resistance will enhance the FF. For example, hybrid cells fabricated on planar Si substrate show cell efficiency of ∼10%, without any structural or interfacial optimization.…”

Optimization of SiO 2 –TiO 2 nanocomposite in hole‐transporting layer (PEDOT:PSS) for enhanced performance of planar Si‐based hybrid solar cells

“…This is usually known as electrical optimization 20,21 . The purpose of this modification is to increase the conductivity of the PEDOT:PSS layer by creating secondary doping through the introduction of co‐solvent or surfactant molecules 22,23 or by creating low sheet resistance through the addition of nanoparticles (NPs) or nanocomposites (NCs) in the layer 24‐26 . Since this organic layer is deposited through solution‐based deposition, the addition of nanomaterials to it is very easy.…”

[24][25][26] Since this organic layer is deposited through solution-based deposition, the addition of nanomaterials to it is very easy. Different nanomaterials have been used to enhance the electrical properties of the hybrid solar cells, that is, gold (Au), silica (SiO 2 ), titania (TiO 2 ), tin oxide (SnO 2 ), indium tin oxide (ITO), etc.…”

Siloxane resins as hydrophobic self-cleaning layers for silicon and dye-sensitized solar cells: material and application aspects

“…In the literature, polysiloxanes in the context of solar cell protection are used mainly as hydrophobizing and coupling agents in complex solutions [31][32][33] or as passivating layers to reduce the charge carrier recombination in silicon-PEDOT:PSS (poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate)). 34 To the best of our knowledge, no reports have been published on the use of polysiloxane as the sole component of the hydrophobic layer for solar cells.…”
