“…It is seen that the I-V characteristic is linear at low reverse bias. Thus the reverse current through the propolis/p-CdTe heterojunction is governed by the leakage current through the large shunt resistance, R sh 9 · 10 6 Ω, which is in good agreement with other hybrid organic-inorganic heterojunctions [10]. However, the reverse I-V characteristics deviates from the Ohmic law with the increase of reverse bias due to the increased contribution of the generation processes within the space charge region, located in the p-CdTe substrate.…”

We report on the analysis of optical, polarimetric, and electrical properties of propolis films and hybrid biomaterial-inorganic heterojunctions based on them. It was shown that the material of the propolis films belongs to wide-bandgap optically active substances with the light-scattering centers, which possess complex optical properties. The values of the specific resistance ρ(P)=1.9·10⁷ Ω·cm and dielectric constant ε(P)=19.5 of the propolis film were determined from the spectral distribution of the real and imaginary components of its impedance at room temperature, respectively. The dominating current transport mechanisms through the hybrid bioinorganic heterojunction propolis/p-CdTe were established to be the interface-states-assisted generation-recombination within the depletion region via deep energy levels at forward bias as well as the leakage current through the shunt resistance at reverse bias.

This work reports on a comparative study comprising three transition metal oxides, MoO 3 , WO 3 and V 2 O 5 , acting as front p-type emitters for n-type crystalline silicon heterojunction solar cells. Owing to their high work functions (>5 eV) and wide energy band gaps, these oxides act as transparent hole-selective contacts with semiconductive properties that are determined by oxygen-vacancy defects (MoO 3-x ), as confirmed by x-ray photoelectron spectroscopy. In the fabricated hybrid structures, 15 nm thick transition metal oxide layers were deposited by vacuum thermal evaporation. Of all three devices, the V 2 O 5 /n-silicon heterojunction performed the best with a conversion efficiency of 15.7% and an open-circuit voltage of 606 mV, followed by MoO 3 (13.6%) and WO 3 (12.5%). These results bring into view a new silicon heterojunction solar cell concept with advantages such as the absence of toxic dopant gases and a simplified low-temperature fabrication process.

The AC properties of high-efficiency (η = 8.01% under standard 100 mW/cm 2 AM1.5 illumination) small-molecule bulk heterojunction (SM BHJ) solar cells (p-DTS(FBTTh 2 ) 2 /PC 70 BM) at different DC biases and frequencies of small amplitude (±10 mV) AC signal in the dark at room temperature were investigated in details. We showed the presence of interface states at the heterojunction interface and determined their parameters from the analysis of spectral distributions of real and imaginary components of the measured impedance. The dielectric constant of BHJ ε BHJ = 2.9 was determined from the geometrical capacitance of totally depleted BHJ layer. We explained quantitatively the effect of interface states and series resistance on the measured C-V characteristics of the SM BHJ solar cells at both low and high frequencies. The quantitative value of the density of defect states in the bulk N = 1.05 × 10 16 cm À3 was determined from the high frequency C-V characteristic corrected by the effect of the series resistance.
