“…The LSPR produce strong evanescent electrical field which can enhance light absorption or light emission in adjacent semiconductor or chemical or biological environment. This is why LSPR in metallic nanoparticles in last two decades have been applying to enhance absorption in conventional or organic photovoltaics [1][2][3] or to enhance light emission in light-emitting device 4,5 . Strong evanescent field in metallic nanoparticles can enhance the emission in weakly fluorescent biomolecules such that it also has been applying in biological sensing [6][7][8][9] .…”

The absorption spectra in array of Ge, Al and Ge/Al-shell nanoparticles immersed in alumina (Al 2 o 3) matrix is calculated in framework of ab initio macroscopic dielectric model. It is demonstrated that absorption is strongly enhanced when germanium nanospheres are encapsulated by Al-shell. Two absorption peaks, appearing in the spectra, correspond to low energy ω + and high energy ω − plasmons which lie in visible and ultraviolet frequency range, respectively. It is demonstrated that in Ge/Al-shell composite the ω + plasmon exists only because quantum confinement effect which provides larger Ge band gap (Δ ~ 1.5 eV) and thus prevent decay of ω + plasmon to continuum of interband electron-hole excitation in semiconducting core. Absorption in visible frequency range enhances additional 3 times when alumina is replaced by large dielectric constant insulator, such as SiC, and additional 6 times when Ge core is replaced by wide band-gap insulator, such as Si 3 n 4. Strong enhancement of optical absorption in visible frequency range make this composites suitable for optoelectronic application, such as solar cells or light emitting devices. The simulated plasmon peaks are brought in connection with peaks appearing in ellipsometry measurements.

“…[28][29][30] In recent years, due to the rapid development of IoT (Internet of Things) related technology, the number of IoT devices has dramatically increased. 31,32 Many type of printable PV devices such as OPVs, [33][34][35][36][37][38][39][40][41][42] dye-sensitized solar cells 43,44 and perovskite solar cells 45,46 have been explored for indoor applications, OPVs are especially expected to be used as an energy harvesting system for IoT devices because of their potential for low power operation, independent and distributed applications, high portability and device designability. In this study, we successfully demonstrated SiNC-HPVs with PCE as high as 9.7% and power density of 34.0 mW cm À2 under standard indoor light irradiation (1000 lx).…”

“…Organic photovoltaic (OPV) devices have been attracting much attention because of their advantageous properties, including light weight, mechanical flexibility, low material and fabrication cost, and short energy payback times [1][2][3][4]. Apart from traditional solar panels, possible applications of OPV devices also include power generators for wearable electronics, portable devices, and the Internet of things (IoTs) [5][6][7][8][9][10]. The state-of-the-art OPV devices are prepared based on the concept of "bulk heterojunction."…”

Herein, we report virtual screening of potential semiconductor polymers for high-performance organic photovoltaic (OPV) devices using various machine learning algorithms. We particularly focus on support vector machine (SVM) and ensemble learning approaches. We found that the power conversion efficiencies of the device prepared with the polymer candidates can be predicted with their structure fingerprints as the only inputs. In other words, no preliminary knowledge about material properties was required. Additionally, the predictive performance could be further improved by “blending” the results of the SVM and random forest models. The resulting ensemble learning algorithm might open up a new opportunity for more precise, high-throughput virtual screening of conjugated polymers for OPV devices.
