“…It was shown that with the increase of Nb concentration from 0 to 3 mol.% the conductivity of a nanocrystalline layered TiO 2 photoelectrode was also increased [69,71]. Later,a similar behavior was observed in PSCs where the use of a TiO 2 layer doped with Nb content of 2.7 mol.%, which resulted in 19 % improvement of a power conversion efficiency [72,73]. The transmittance spectra in Nb-doped TiO 2 photoelectrodes presented in Fig.…”

“…The PSC fabrication process was provided under ambient conditions with high humidity (∼ 50 -60 %) using a one-step method described previously [15]. During the fabrication process, ZrO 2 -based photoelectodes were first coated with a photosensitive perovskite (CH 3 NH 3 PbI 3 ) layer, obtained from lead iodide and methylammonium iodide precursor solutions, followed by depositing a layer of spiro-MeO-TAD as a hole-transporting material [7,14].…”

Very wide-bandgap undoped and Y 2 O 3-doped ZrO 2 nanoparticles were synthesized and their structural, optical, morphological and energy characteristics were investigated. It was found that the bandgap value in ZrO 2 decreases with Y 2 O 3 doping. The developed materials were used for fabrication of nanostructured photoelectrodes for perovskite solar cells (PSCs) with the architecture of glass/FTO/ZrO 2-Y 2 O 3 /CH 3 NH 3 PbI 3 /spiro-MeOTAD/Au. The power conversion efficiency in the PSCs based on ZrO 2-Y 2 O 3 photoelectrodes was significantly higher than that for undoped ZrO 2 photoelectrodes. We have found that nanostructured layers, based on very wide-bandgap materials could efficiently transfer the injected electrons via a hopping transport mechanism.

“…При создании фотоэлектродов для PSC мезоскопические слои TiO 2 толщиной 400 нм наносились методом спин-коутинга [16,17] и подвергались отжигу при 500 • C в течение 30 мин, затем кипячению в течение 10 мин при 90 • C в 0.2 мМ водном растворе TiCl 4 и повторному отжигу при 500 • C в течение 30 мин. Непосредственно перед нанесением фотоэлектродных слоев подложки предварительно покрывались блокирующим слоем, который предотвращал возможный электрический контакт между перовскитом и FTO-покрытием [16].…”

“…Дальнейшая сборка PSC проводилась в атмосферных условиях при высокой влажности (∼ 50−60%) согласно методике, подробно описанной нами ранее [16] Сравнительные исследования работы СЭ вида DSC, PSC и c-Si проводились с использованием солнечного имитатора Abet 10500 (Abet Technologies, США) как в условиях стандартного солнечного излучения в 1000 Вт/м 2 (АМ1.5G), так и при изменяемой интенсивности освещения (10−1000 Вт/м 2 ). Уменьшение интенсивности освещения достигалось с помощью специальных нейтральных фильтров (Marumi, Япония), которые обеспечивали равномерное уменьшение светового потока в спектральном диапазоне от 300 до 1100 нм.…”

We present the results of a comparative study on behaviour of the photovoltaic parameters in perovskite (PSC), dye-sensitized (DSC) and crystalline silicon ( c -Si) solar cells under various intensities of solar radiation (10–1000 W/m^2). It was found that unlike c -Si, the power conversion efficiencies of PSC and DSC under low radiation intensities are comparable with the corresponding values observed under standard light intensity of 1000 W/m^2 (AM1.5G). We have shown that high performance of the PSC and DSC at low and diffuse lighting conditions can be explained by the properties of the nanostructured TiO_2-based photoelectrodes depending on the structure, morphology and the thickness of the TiO_2 layers.
