Integrating dye-sensitized solar cells (DSSCs) with a building's architecture is required for its commercialization. Coupling semitransparent designer DSSCs windows has the dual benefit of providing daylighting and power generation. To achieve this, we report low-cost, novel, high-pressure exfoliation technique graphene utilize it as transparent counter electrode fabrication DSSCs. By adopting environmentally friendly economic exfoliated instead conventional platinum, overall device cost...
Abstract The exponential increase in demand for global energy intake day-to-day life directs us to look a green and cost-effective generation storage alternative. India being fastly developing nation with vast population, requires the alternative resource meet up deficit an eco-friendly manner be self-reliant demands. This review aims compile assess developments materials research from Indian prospects. Therefore, this paper discusses India’s scenario by understanding fundamental concepts of...
Here, we present an environmentally friendly, cost-effective, large-scale production of water-based graphene suspensions by the liquid phase high shear exfoliation method natural graphite. The produced are stable for a period exceeding year. As-prepared used to fabricate transparent platinum-free counter electrodes, having transparency comparable with bare fluorine-doped tin oxide and thereby semi-transparent dye-sensitized solar cells (DSSCs), ≈70% transmittance. performance this...
In perovskite solar cells (PSCs), defects and interfacial properties are critical govern the device's performance. To enhance performance, effective defect passivation recombination reduction crucial. This work reports phenethylammonium iodide (PEAI) treatment of lead-excess film for low-temperature carbon-based PSCs. The PEAI post-treatment leads to formation a crystallized (PEA)2PbI4 2D layer on top 3D perovskite. Apart from passivating grain boundaries, 3D/2D stack improves interface...

Herein, low‐cost, solution‐based, all room‐temperature‐processed carbon‐based triple‐cation perovskite solar cells (C‐PSC) with TiO 2 electron transport layer (ETL) are reported. The hydrothermally synthesized anatase nanoparticles titanium diisopropoxide bis(acetylacetonate) doping results in high‐quality and uniform ETL improved interparticle connectivity. room‐temperature crystallization of pure photoactive α‐phase absorber MA 0.14 FA 0.77 Cs 0.09 PbI 2.5 Br 0.5 is achieved the...
Perovskite solar cells, despite showing promising efficiency of more than 22%, is still far from realizing its full prospect on commercial scale, majorly owing to the cost associated with gold or silver counter electrode as well hole transport material. Herein we report, low temperature processed carbon paste for layer free perovskite cell (PSC) fabricated in ambient conditions. Conductive (11.46 Ω □ <sup xmlns:mml="http://www.w3.org/1998/Math/MathML"...
Thermoplastic polyolefin (TPO) is a newly developed non-crosslinking encapsulant for the crystalline silicon PV modules lamination. The degree of crystallinity and thermal stability TPO have been studied compared with most commonly used ethylene vinyl acetate (EVA) copolymer encapsulant. peak melting point determined help differential scanning calorimeter (DSC) analysis. both also x-ray diffraction. DSC results show that there no crosslinking reaction involved in Thermogravimetric analysis...
All-inorganic cesium lead bromide (CsPbBr3) perovskite solar cells (PSCs) have gained significant attention due to their superior stability compared that of organic–inorganic hybrid devices. In this study, we employ a vacuum-deposited cadmium sulfide (CdS) interfacial layer address the challenge achieving high open-circuit voltage (Voc) in CsPbBr3 PSCs. Incorporating thin CdS between electron transport (ETL) and inorganic absorber enhances Voc 1.7 V, along with power conversion efficiency...
Ethylene Vinyl Acetate (EVA) Copolymer is a most commonly used encapsulant for PV module lamination. Using cured and uncured EVA, several key characteristics of EVA have been determined. The glass transition temperature, peak melting point, degree crystallinity has determined with the help Differential scanning calorimeter (DSC) analysis. Thermogravimetric analysis (TGA) done to determine content thermal stability based on degradation onset temperature. This work will understand behavior...
Rutile TiO2 films were deposited on the FTO substrate by hydrothermal process using TTIP and TiCl4 as titania precursor. Our study manifestly exhibits influence of precursor growth structure. The morphology prepared film varies from nano-cauliflower to nano-flower nano-parallelepiped rod-like structure with addition When is introduced in HCl corresponding four times Ti4+ concentration generated a by-product during reaction, these additional promotes etching nanostructure enabling unfurl.
