Decal Ni mesh to enhance the conductivity of carbon back contacts in dye sensit...

Dye-sensitized solar cells (DSSCs) and perovskite solar cells (PSCs) are photovoltaic (PV) technologies that originally utilized precious metals like gold, silver, and platinum as counter-electrodes. Carbon materials are a low-cost alternative to traditional metal counter-electrodes in monolithic-DSSCs (M-DSSCs) and PSCs. However, the drawback of carbon-based counter-electrodes is that they often show a low ele...

PEROVSKITE SOLAR CELL, METHODS AND USES THEREOF

The present disclosure relates a process for immobilization of soluble lead compounds in perovskite solar cells in the case of the cell breakage or of fire by introducing the additives in the cells. The said additives in the presence of water interact with lead-based components of the perovskite cell via ion-exchange reaction forming less soluble compounds with higher thermal stability. The less soluble lead co...

Advanced hermetic encapsulation of perovskite solar cells: the route to commerc...

Though perovskite solar cells (PSCs) are rapidly emerging into the photovoltaic (PV) community, their long-term stability raises huge concerns for their future commercialization. PSCs are sensitive to humidity and temperature. A hermetic encapsulation is crucial for PSCs not only to prevent them from external environmental effects but also to avoid leakage of Pb-containing materials of the cells. An advanced la...

Advanced hermetic encapsulation of perovskite solar cells

Novel laser-assisted glass frit encapsulation for long-lifetime perovskite sola...

Hermetic encapsulation protects perovskite solar cells (PSCs) from degradations induced by humidity and oxygen. A novel dual laser beam glass frit sealing process is developed and optimized to hermetically encapsulate PSCs. A 3D transient phenomenological model of the laser-assisted encapsulation is developed, validated and used to optimize the glass sealing procedure. During the laser-sealing process, the cell...

Development of hermetic glass frit encapsulation for perovskite solar cells

A hermetic laser-assisted glass frit encapsulation, at a process temperature of 120 degrees C, was developed for perovskite solar cell application. The hermeticity and long-term stability of the sealing was examined based on standard tests for photovoltaic (PV) applications. Encapsulations using fluorine doped tin oxide (FTO)-coated glass substrates displayed 8.93 x 10(-8) atm center dot cm(3) center dot s(-1) ...

Low temperature hermetic laser-assisted glass frit encapsulation of soda-lime g...

Room temperature and low temperature (120 degrees C) laser-assisted glass frit bonding of soda-lime glass substrates are accomplished in this work. The locally laser melted bonding showed hermeticity with helium leak rate of < 5 x 10(-8) atm cm(3) s(-1), maintaining its leak rate even after standard climatic cycle tests. Small size devices were bonded at room temperature while larger areas were sealed at the pr...

Toward the construction of 3D dipeptide-metal frameworks

Single amino acids have been vastly used to generate metal−biomolecule frameworks. Three-dimensional (3D) frameworks based on di- and tripeptide frameworks remain nevertheless quite scarce. We report the preparation of unique 3D dipeptide−metal frameworks in which both amino acid residues participate in metal coordination and in the construction of the networks.
