“…According to photocell CVC, the average values of photocell parameters and their relative changes were determined: V ocno-load voltage; (V oc −V oc1 )/V oc1 -relative change in no-load voltage (relative to the average value for the samples of group 1a); J s cshort circuit current density;(J s c −J s c1 )/J s c1the change in short circuit current density (relative to the average value for the samples of group 1a); P peakspecific peak power (calculated as the product of J s c and V oc ); (P peak −P peak1 )/P peak1 -relative change in specific peak power (relative to the average value for the samples of group 1a). Photocell parameters were rather low due high base volume resistivity [14] and large sample thicknesses [15,16].…”

In this work, the parameters of silicon-based photocells doped with impurity nickel atoms by diffusion methods and during growth were compared. It was found that photocells doped with impurity nickel atoms during silicon growth have an improvement in parameters comparable to that obtained by the diffusion doping method. Additional heat treatment at T=800oC makes it possible to significantly improve their basic parameters. Keywords:silicon, photocell, nickel, thermal annealing, diffusion.

“…This is related to the nonperpendicular light incidence on the textured elements of the structure, which leads to an increase in the photon path length due to the multiple total internal reflection and to an increase in the absorption in the long-wavelength region. It was established in [30,31] that the absorption edge in silicon HIT SCs and FAPbI 3 -based SCs can be described by the generalized expression which differs from (8) by the presence of the parameter : where ≥ 1 is a dimensionless parameter equal to the ratio of the longest possible photon path length, 4 2 at the ideal Lambertian light trapping to its real value. This ratio depends on the texturing quality (degree of light capture) and the film thickness.…”

“…We note that the case when the expression (4) with b=1 is realized experimentally is rare. In particular, it was demonstrated in [24] that the experimental results for the textured silicon-based SCs and textured HIT elements near the absorption edge can be described theoretically with a transformed expression of the form (6) with b > 1.…”

We present the results of studies of the photoelectric properties of perovskite CH3NH3PbI2.98Cl0.02 films deposited on a glass substrate using the spin-coating method. The unit cell parameters of perovskite are determined, by using X-ray diff ractometry. It is shown that the fi lm morphology represents a net of non-oriented needle-like structures with significant roughness and porosity. In order to investigate the properties of the films obtained, we used non-contact methods such as transmission and reflection measurements and the measurements of the spectral characteristics of the small-signal surface photovoltage. The non-contact method of spectral characteristics of the small-signal surface photovoltage and the transmission method reveal information about the external quantum yield in the films studied and about the diffusion length of minority carriers in the perovskite films. As a result of this analysis, it has been established that the films are naturally textured, and their bandgap is 1.59 eV. It is shown that, in order to correctly determine the absorption coefficient and the bandgap values, the Urbach effect should be accounted for. The diffusion length of minority carriers is longer than the fi lm thickness, which is equal to 400 nm. The films obtained are promising materials for solar cells and optoelectronic devices.

“…Using obtained data of climate regime in the investigated region, we modeled the operating conditions for the RES systems. The data was obtained from the National Aeronautics and Space Administration (NASA) Langley Research Center (LaRC) Prediction of Worldwide Energy Resource (POWER) Project funded through the NASA Earth Science/Applied Science Program [15][16][17][18][19][20][21][22][23]. Two regions with similar climatic regime in the area of Gulf Of Finland were investigated.…”

Study of the joint daily variability of wind speed and solar activity in the region of Gulf of Finland and its impact on renewable energy sources. The influence of external factors on the variability of total output power of ground-based wind turbines and solar photovoltaic panels is investigated. To a small extent, wind turbines are able to complement the generation of renewable energy sources: 15% –30% wind turbines and 70% –85% solar photovoltaics is preferable ratio of renewable energy sources. Comparing two similar climate regions in different scenarios lead economic feasibility strongly corelate with fuel prices. Standalone diesel generators can be quite effective at first, but in the long-term it is not viable solution due to fuel costs. Combined wind-PV renewable energy system is more profitable, but it has higher initial cost.
