Network time series forecasting in photovoltaics power production

Jelena Simeunovic

Accurate forecasting of photovoltaic (PV) power production is crucial for the integration of more renewable energy sources into the power grid. PV power production is highly intermittent, due to the stochastic cloud behaviour and cloud dynamics. Previous w ...

Advanced Manufacturing and Characterization of Building-Integrated Photovoltaic Modules

Alejandro Borja Block

Photovoltaic (PV) technology is necessary for global decarbonization. However, one of the challenges of the technology is that its land use may conflict with other space demands. Building-integrated photovoltaic (BIPV) is a solution to efficiently use the ...

Rationalizing Performance Losses of Wide Bandgap Perovskite Solar Cells Evident in Data from the Perovskite Database

Christian Michael Wolff, Tor Jesper Jacobsson

Metal halide perovskites (MHPs) have become a widely studied class of semiconductors for various optoelectronic devices. The possibility to tune their bandgap (E-g) over a broad spectral range from 1.2 eV to 3 eV by compositional engineering makes them par ...

Chemical Trend of Nonradiative Recombination in Cu(In,Ga)Se2 Alloys

Stefano Falletta

Nonradiative recombination in Cu(In,Ga)Se2 (CIGS) solar cells has long been attributed to the antisite defects MCu (M = In, Ga), but the underlying mechanism is still elusive. Using rigorous first-principles calculations, we demonstrate that the antisites ...

A critical perspective for emerging ultra-thin solar cells with ultra-high power-per-weight outputs

Michael Graetzel, Essa Awadh R Alharbi, Georgios Kakavelakis, Apostolos Panagiotopoulos

Ultrathin, solution-processed emerging solar cells with high power-per-weight (PPW) outputs demonstrate unique potential for applications where low weight, high power output, and flexibility are indispensable. The following perspective explores the literat ...

Rear textured p-type high temperature passivating contacts and their implementation in perovskite/silicon tandem cells

Christophe Ballif, Quentin Thomas Jeangros, Antoine Descoeudres, Andrea Ingenito, Arnaud Walter, Sylvain Nicolay, Soo-Jin Moon, Philippe Wyss

Silicon solar cells based on high temperature passivating contacts are becoming mainstream in the photovoltaic industry. Here, we developed a high-quality boron-doped poly-silicon hole contact. When combined with a co-processed phosphorus-doped poly-silico ...

Lead immobilization for environmentally sustainable perovskite solar cells

Michael Graetzel, Antonio Abate, Hui Zhang

Lead halide perovskites are promising semiconducting materials for solar energy harvesting. However, the presence of heavy-metal lead ions is problematic when considering potential harmful leakage into the environment from broken cells and also from a publ ...

Interface and structural engineering of perovskite solar cells towards enhanced stability and performance

Masaud Hassan S Almalki

Perovskite solar cells have had a meteoric rise in the last decade achieving efficiencies that already rival the most established solar cells technologies. They are easily processed and have excellent optoelectronic properties that make them accessible for ...
