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 ...

Back-contacted emitter GaAs solar cells [PDF]

Applied Physics Letters, 1990
A new device structure to improve the performance of concentrator GaAs solar cells is described and the first experimental results are reported. The reason for such an improvement relies on a drastic reduction of the shadowing and series resistance losses based on the possibility of back contacting the emitter region of the solar cell. The experimental

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 ...

Back-Contact Perovskite Solar Cells [PDF]

Scientific Video Protocols, 2019
Interdigitated back-contact (IBC) architectures are the best performing technology in crystalline Si (c-Si) photovoltaics (PV). Although single junction perovskite solar cells have now surpassed 23% efficiency, most of the research has mainly focussed on planar and mesostructured architectures.
