Nonfullerene Acceptor Molecules for Bulk Heterojunction Organic Solar Cells.

Chemical Reviews, 2018
The bulk-heterojunction blend of an electron donor and an electron acceptor material is the key component in a solution-processed organic photovoltaic device.

Recent Progress of Heterojunction Ultraviolet Photodetectors: Materials, Integrations, and Applications

Advanced Functional Materials, 2020
Ultraviolet photodetectors (UV PDs) with “5S” (high sensitivity, high signal‐to‐noise ratio, excellent spectrum selectivity, fast speed, and great stability) have been proposed as promising optoelectronics in recent years.

The Heterojunction with Light

1992
As an example of the thin heterojunction polycrystalline solar cell, the CdS/Cu2S cell is chosen. The current voltage characteristic is computed. Space charge effects in the heterojunction are discussed. The influence of electron traps in CdS is shown. The influence of a field enhanced depletion of hole traps is experimentally demonstrated.

pSi-nCdS Heterojunction Photodetectors

Physica Status Solidi (a), 1978
Heterojunctions of the type pSinCdS are fabricated by depositing epitaxial films on single crystal silicon substrates using the technique of electron beam evaporation of CdS powder under UHV conditions. The basic junction properties such as photo-conduction, I–U and C–U characteristics are investigated.

Electrons in Heterojunctions

1986
Properties of electrons — and, in a few cases, of holes — in heterojunctions are described, with emphasis on simple treatments of energy levels and low-temperature transport properties in A1xGa1-xAs/GaAs heterojunctions. A few related aspects of electrons in quantum wells are also described.

Variational method in a heterojunction

Physical Review B, 1991
Determination des expressions analytiques de l'energie de l'etat fondamental et de la 1ere sous-bande d'une heterojonction en fonction de la temperature et de la concentration en electrons. La difference d'energie E 10 entre la premiere sous-bande et l'etat fondamental est en accord raisonnable avec les donnees obtenues dans une heterojonction GaAs-Ga
