Poly-crystalline silicon-oxide films as carrier-selective passivating contacts for c-Si solar cells

Yang, G. (author), Guo, Peiqing (author), Procel Moya, P.A. (author), Weeber, A.W. (author), Isabella, O. (author), Zeman, M. (author)

The poly-Si carrier-selective passivating contacts (CSPCs) parasitically absorb a substantial amount of light, especially in the form of free carrier absorption. To minimize these losses, we developed CSPCs based on oxygen-alloyed poly-Si (poly-SiO_x) and deployed them in c-Si solar cells. Transmission electron microscopy analysis...

In this work we consider noise barriers with integrated photovoltaic modules. The novelty is that bifacial modules are considered. A full scale bifacial photovoltaic noise barrier was built and its power output was monitored. In addition we developed an advanced numerical model for predicting this power output for given weather conditions....

Multi-junction solar cells are considered for various applications, as they tackle various loss mechanisms for single junction solar cells. These losses include thermalization and non-absorption below the band gap. In this work, a tandem configuration comprising copper-indium-gallium-di-selenide (CIGS) and hydrogenated amorphous silicon (a-Si...

Improving the Back Surface Field on an Amorphous Silicon Carbide Thin Film Photocathode for Solar Water Splitting

Perez Rodriguez, P. (author), Cardenas-Morcoso, Drialys (author), Digdaya, I.A. (author), Mangel Raventos, A. (author), Procel Moya, P.A. (author), Isabella, O. (author), Gimenez, Sixto (author), Zeman, M. (author), Smith, W.A. (author), Smets, A.H.M. (author)

Amorphous silicon carbide (a-SiC:H) is a promising material for photoelectrochemical water splitting owing to its relatively small band-gap energy and high chemical and optoelectrical stability. This work studies the interplay between charge-carrier separation and collection, and their injection into the electrolyte, when modifying the...

Oxidation-Induced Structure Transformation: Thin-Film Synthesis and Interface Investigations of Barium Disilicide toward Potential Photovoltaic Applications

Tian, Y. (author), Vismara, R. (author), van Doorene, S. (author), Šutta, Pavol (author), Vančo, L’ubomír (author), Veselý, Marian (author), Vogrinčič, Peter (author), Isabella, O. (author), Zeman, M. (author)

Barium disilicide (BaSi2) has been regarded as a promising absorber material for high-efficiency thin-film solar cells. However, it has confronted issues related to material synthesis and quality control. Here, we fabricate BaSi2 thin films via an industrially applicable sputtering process and uncovered the mechanism of structure transformation....

Estimating battery lifetimes in Solar Home System design using a practical modelling methodology

Narayan, N.S. (author), Papakosta, Thekla (author), Vega Garita, V.E. (author), Qin, Z. (author), Popovic, J. (author), Bauer, P. (author), Zeman, M. (author)

The rapid increase in the adoption of Solar Home Systems (SHS) in recent times hopes to ameliorate the global problem of energy poverty. The battery is a vital but usually the most expensive part of an SHS; owing to the least lifetime among other SHS components, it is also the first to fail. Estimating battery lifetime is a critical task for...

Theoretical evaluation of contact stack for high efficiency IBC-SHJ solar cells

Procel Moya, P.A. (author), Yang, G. (author), Isabella, O. (author), Zeman, M. (author)

In this work we present a theoretical analysis of charge carriers transport mechanisms in IBC-SHJ solar cells. The concepts of contact and transport selectivity are correlated through the band bending at c-Si interface and are used to identify thin-film silicon parameters affecting fill factor (FF) and open-circuit voltage (V_OC)....

A photovoltaic window with sun-tracking shading elements towards maximum power generation and non-glare daylighting

Gao, Y. (author), Dong, J. (author), Isabella, O. (author), Santbergen, R. (author), Tan, H. (author), Zeman, M. (author), Zhang, Kouchi (author)

Vertical space bears great potential of solar energy especially for congested urban areas, where photovoltaic (PV) windows in high-rise buildings can contribute to both power generation and daylight harvest. Previous studies on sun-tracking PV windows strayed into the trade-off between tracking performance and mutual shading, failing to achieve...

High-efficiency black IBC c-Si solar cells with poly-Si as carrier-selective passivating contacts

Yang, G. (author), Guo, Peiqing (author), Procel Moya, P.A. (author), Limodio, G. (author), Weeber, A.W. (author), Isabella, O. (author), Zeman, M. (author)

In this work, we present the application of poly-Si carrier-selective passivating contacts (CSPCs) as both polarities in interdigitated back-contacted (IBC) solar cell architectures. We compared two approaches to form a gap between the back-surface field (BSF) and emitter fingers. It is proved that the gaps prepared by both approaches are...

Electroluminescence and Dark Lock-In Thermography for the Quality Assessment of Metal-Wrap-Through Solar Devices

Ruggeri, Edoardo (author), van Aken, Bas (author), Isabella, O. (author), Zeman, M. (author)

Imaging techniques, like electroluminescence and dark lock-in thermography, are valuable quality control tools as they yield quantitative and spatially resolved information about the device. In this paper, we isolated some of the conductive foil–cell interconnections of back-contact solar cells to study the appearance of these...

Distinguishing Fabry-Perot from guided resonances in thin periodically-textured silicon absorbers

Ahmadpanahi, S.H. (author), Vismara, R. (author), Isabella, O. (author), Zeman, M. (author)

Periodic texturing is one of the main techniques for light-trapping in thin-film solar cells. Periodicity allows for the excitation of guided modes in the structure and, thus, largely enhances absorption. Understanding how much a guided resonance can increase the absorption is therefore of great importance. There is a common method to understand...

Ahmadpanahi, S.H. (author), Vismara, R. (author), Isabella, O. (author), Zeman, M. (author)

Total electric field in a periodic thin-film structure is described by its Fourier coefficients. These coefficients can be used to calculate the share of different resonances in total absorption in the structure.

Quenching Mo optical losses in CIGS solar cells by a point contacted dual-layer dielectric spacer: A 3-D optical study

Rezaei, N. (author), Isabella, O. (author), Vroon, Zeger (author), Zeman, M. (author)

A 3-D optical modelling was calibrated to calculate the light absorption and the total reflection of fabricated CIGS solar cells. Absorption losses at molybdenum (Mo) / CIGS interface were explained in terms of plasmonic waves. To quench these losses, we assumed the insertion of a lossless dielectric spacer between Mo and CIGS, whose optical...

The past few years have seen strong growth of solar-based off-grid energy solutions such as Solar Home Systems (SHS) as a means to ameliorate the grave problem of energy poverty. Battery storage is an essential component of SHS. An accurate battery model can play a vital role in SHS design. Knowing the dynamic behaviour of the battery is...
