Injection-dependent lateral resistance in front-junction solar cells with nc-Si:H and a-Si:H hole selective contact

Christophe Ballif, Mathieu Gérard Boccard, Jan Haschke, Jean Cattin

We investigate the role of lateral transport of minority carriers in the wafer for front-junction solar cells. The study is based on two silicon heterojunction solar cells with p-type amorphous (a-Si), and nanocrystalline (nc-Si) silicon as hole selective ...

Annealing of Silicon Heterojunction Solar Cells: Interplay of Solar Cell and Indium Tin Oxide Properties

Christophe Ballif, Raphaël François Lemerle, Mathieu Gérard Boccard, Jan Haschke, Brahim Aissa

In this paper, we report the evolution of silicon heterojunction solar cell properties focusing, in particular, on the indium tin oxide (ITO) layers upon consecutive thermal annealing. We find that the charge carrier density

Numerical simulations of hole carrier selective contacts in p-type c-Si solar cells

Christophe Ballif, Andrea Ingenito, Philipp Friedrich Hermann Löper

This work presents a systematic analysis of the transport mechanism and surface passivation of tunneling oxide (SiO2)/p-type poly-silicon (poly-Si(p)) junctions applied to p-type crystalline silicon (c-Si) solar cells by means of TCAD numerical simulations ...

Advances in the characterization of nanowire photovoltaic devices

Dmitry Mikulik

III-V nanowires (NWs) have a great potential for solar energy applications due to their diameter-dependent optical properties, which may enhance absorption of light. In addition, core-shell radial p-i-n structures, in which the direction of light absorptio ...

Full-Area Passivating Contacts with High and Low Thermal Budgets: Solutions for High Efficiency c-Si Solar Cells

Gizem Nogay

Today more than 90% of the global PV market is covered by c-Si solar cells which are limited by recombination losses at the metal-semiconductor interface. This recombination path can be avoided by separating the metal from the c-Si wafer by introducing a b ...

Dynamics of Electronic and Ionic Charges in Cyanine Organic Semiconductor Devices

Sandra Christina Jenatsch

Organic semiconductor materials have been widely applied in optoelectronic devices to replace their inorganic counterparts and explore new fields of applications. Due to their high extinction coefficients, chemical tunability and solubility, cyanine dyes a ...

A novel perovskite solar cell design using aligned TiO2 nano-bundles grown on a sputtered Ti layer and a benzothiadiazole-based, dopant-free hole-transporting material

Mohammad Khaja Nazeeruddin

This work highlights the utilization of a novel hole-transporting material (HTM) derived from benzothiadiazole: 4-(3,5-bis(trifluoromethyl) phenyl)-7-(5'-hexyl-[2,2'-bithiophen]-5-yl) benzo[c][1,2,5] thiadiazole (CF-BTz-ThR) and aligned TiO2 nano-bundles ( ...

Increasing the efficiency of silicon heterojunction solar cells and modules by light soaking

Christophe Ballif, Franz-Josef Haug, Antoine Descoeudres, Jacques Levrat, Matthieu Despeisse, Stefaan De Wolf, Eiji Kobayashi

Silicon heterojunction solar cells use crystalline silicon (c-Si) wafers as optical absorbers and employ bilayers of doped/intrinsic hydrogenated amorphous silicon (a-Si:H) to form passivating contacts. Recently, we demonstrated that such solar cells incre ...
