The Effects of ZnTe:Cu Back Contact on the Performance of CdTe Nanocrystal Solar Cells with Inverted Structure [PDF]

Nanomaterials, 2019
CdTe nanocrystal (NC) solar cells have received much attention in recent years due to their low cost and environmentally friendly fabrication process. Nowadays, the back contact is still the key issue for further improving device performance.

The Electrical Contact Solution for Measuring Back Contact Solar Cells

SiliconPV Conference Proceedings
Due to the cell design, it is challenging to measure back contact cells. In this study, we have designed and tested a contact chuck based on printed circuit board (PCB) technology.

Printing Hybrid, Interdigitated Back-Contact Solar Cells [PDF]

Materials (Basel)
Interdigitated back contact solar cells were fabricated entirely with inkjet printing. PEDOT: PSS films with co-solvents and TiO2 suspension were printed on a textured silicon substrate with only one inkjet printer as was the metal ink. Adding co-solvent to the PEDOT:PSS and passivation of the Si surface significantly reduced the losses and enhanced ...

Well Intended Contact Failures on Interdigitated Back Contact Solar Cells

SiliconPV Conference Proceedings
The interconnection of the cells that make up a solar panel is a simple step, but it is not unimportant. The panels are made up of cells in series, so that a poorly connected cell can spoil the good performance of the entire panel.

From Contact Relations to Modal Operators, and Back

Studia Logica, 2023
AbstractOne of the standard axioms for Boolean contact algebras says that if a regionxis in contact with the join ofyandz, thenxis in contact with at least one of the two regions. Our intention is to examine a stronger version of this axiom according to which ifxis in contact with the supremum of some familySof regions, then there is a yinSthat is in ...

Stable reverse bias or integrated bypass diode in HIP‑MWT+ solar cells

EPJ Photovoltaics, 2022
The Metal Wrap Through+ (HIP-MWT+) solar cell is based on the PERC concept but features two additional electrical contacts, namely the Schottky contact between p-type Si bulk and Ag n-contact and the metal-insulator-semiconductor (MIS) contact on the ...

Phototransistor Behavior in CIGS Solar Cells and the Effect of the Back Contact Barrier

Energies, 2020
In this paper, the impact of the back contact barrier on the performance of Cu (In, Ga) Se2 solar cells is addressed. This effect is clearly visible at lower temperatures, but it also influences the fundamental parameters of a solar cell, such as open ...
