Intrinsic photoluminescence Stokes shift in semiconductors demonstrated by thin-film CdS formed with pulsed-laser deposition [PDF]

open access: yes, 2014
While not reported in the literature, by employing highly oriented, semi-insulating, thin-film CdS as test material, we present the observation of the intrinsic photoluminescence Stokes shift in a semiconductor.

Understanding the Formation Process of Perovskite Layers Grown by Chemical Vapour Deposition

open access: yesFrontiers in Energy Research, 2022
This work aims at extending the understanding of the formation processes of (Cs0.07FA0.93)PbI3 perovskite layers deposited by a two-step vapour method. In a first step, an inorganic CsI/PbI2 precursor stack is deposited by thermal evaporation (TE).

Single-graded CIGS with narrow bandgap for tandem solar cells

open access: yesScience and Technology of Advanced Materials, 2018
Multi-junction solar cells show the highest photovoltaic energy conversion efficiencies, but the current technologies based on wafers and epitaxial growth of multiple layers are very costly. Therefore, there is a high interest in realizing multi-junction

Preparation and characterization of suitable insulating and transparent conducting thin films for thin film electroluminescent devices by sol-gel process [PDF]

open access: yes, 2001
Thin film electroluminescent (TFEL) displays are attractive because they are light, have low power consumption, wide viewing angle and long lifetime, are extremely rugged and can be used in hostile environments.

Bulk and surface recombination properties in thin film semiconductors with different surface treatments from time-resolved photoluminescence measurements

open access: yesScientific Reports, 2019
The knowledge of minority carrier lifetime of a semiconductor is important for the assessment of its quality and design of electronic devices. Time-resolved photoluminescence (TRPL) measurements offer the possibility to extract effective lifetimes in the
