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

open access: yesEPJ 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 ...

From Contact Relations to Modal Operators, and Back

open access: yesStudia 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 ...

Fabrication methods for high reflectance dielectric-metal point contact rear mirror for optoelectronic devices

open access: yesMethodsX, 2022
The patterned dielectric back contact (PDBC) structure can be used to form a point-contact architecture that features a dielectric spacer with spatially distributed, reduced-area metal point contacts between the semiconductor back not recognized contact ...

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

open access: yesEnergies, 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 ...

All-Back-Contact Perovskite Solar Cells Using Cracked Film Lithography

open access: yes, 2022
All-back-contact perovskite solar cells promise greater power conversion efficiency compared to conventional planar device architectures. However, the best-performing devices to date use photolithography to fabricate electrodes, which is expensive for ...

ZnO thickness and ZnTe back contact effect of CdTe thin film solar cell Voc and efficiency progression

open access: yesMaterials Research Express, 2021
CdTe thin film (TF) solar cells are most promising photovoltaic (PV) technology in commercial platform. Back contacts and interface defects related opto-electrical losses are still vital to limit its further technological benefit.

Electrodeposition of Bi2Te3 thin films onto FTO substrates from DMSO solution

open access: yesInternational Journal of Electrochemical Science, 2015
We report the pulsed electrodeposition (PED) of Bi2Te3 thin films from TeCl4 and Bi(NO3)3 precursors dissolved in dimethylsulfoxide (DMSO) onto SnO2:F coated glasses (FTO) and CdTe/FTO substrates.

Back contacts materials used in thin film CdTe solar cells—A review

open access: yesEnergy Science & Engineering, 2021
CdTe is the leading commercial thin film photovoltaic technology with current record laboratory efficiency (22.1%). However, there is much potential for progress toward the Shockley‐Queisser limit (32%).
