DESY’s Post

Maximizing the detection efficiency of X-ray excited optical luminescence (#XEOL) instruments is the only way to get measurements done on perovskite solar cells before they die from focused hard X-rays. Happy to share our latest paper in PRX Energy about Axolotl, a new instrument at DESY beamline P06 for temporally and spectrally resolved XEOL measurements that we've used to map out nanoscale inhomogeneities in perovskite solar cells induced by Cs. Thanks for a fantastic collaboration between #DESY, #UHH, and #KAUST! Christina Fröhlich (geb.

The following bar graph projects the global demand for various solar cell technologies from 2023 to 2027. It shows that the demand for P-type cells, represented by dark blue bars, will significantly decrease following 2023 and 2024. Meanwhile, N-type cells are forecasted to dominate the market for the following years. The graph also anticipates steady increases in demand for back-contact cells and thin film technologies over the time period. What do you think? Do you think BC cells will account for much more than this (TBC most likely)? How about the emergence of perovskite solar cells? Leave your comments below. #solar #photovoltaic #photovoltaik

According to Longi, the efficiency of a solar cell made of perovskite and silicon is 33.9%.  https://lnkd.in/dwAsZ5_g 

Triple-junction perovskite–perovskite–silicon solar cell achieves record-breaking efficiency of 24.4%: Developed by scientists in Germany, the triple-junction cell is based on a perovskite top cell with an energy bandgap of 1.84 eV, a perovskite middle cell with bandgap of 1.52 eV, and a silicon bottom cell with a bandgap of 1.1 eV. The device achieved an open-circuit voltage of 2.84 V, a short-circuit current of 11.6 mA cm–2, and a fill factor of 74%. #ModulesUpstreamManufacturing #TechnologyandRD #Perovskite

Chinese scientists boost perovskite solar cell efficiency to a record high of 25.5%. Perovskite solar cells are a type of solar cell that uses a hybrid organic-inorganic material as the light-absorbing layer. They are cheap, easy to make, and flexible but have challenges with stability and durability. #perovskite #solar #efficiency https://buff.ly/3CKrx18

N-Type solar panels are the next evolution in solar cell technology. Unlike the more commonly used P-Type solar cells, N-Type panels use N-Type silicon as the base material. #solarpanels #solarinstallation #westernaustralia #perth https://hubs.ly/Q027_z9P0

❓ Ever wondered about the untapped potential of metal oxide semiconductors in Photovoltaic cells? Our recent paper, "BiVO4–Liquid Junction Photovoltaic Cell with 0.2% Solar Energy Conversion Efficiency," published in JACS, explores the photo-electrochemistry of BiVO4, not for water oxidation, but for generating electricity! 📖 In this study, we explore the interplay of BiVO4 with the triiodide/iodide redox couple, by tracking the photovoltage of solid-liquid junction with Surface Photovoltage spectroscopy. 🚀 The findings enhance our understanding of the photo-electrochemistry of BiVO4, and showcase the possibility of metal oxide−liquid solar cells with aqueous redox couples. 💡 Did you know? The only other examples of such cells date back to 1970's, involving a TiO2 photogalvanic cell based on the O2/H2O redox couple. 🔬 Curious minds, let's explore the potential of metal oxide semiconductors and its implications for the photovoltaic cells. Your thoughts and questions are more than welcome! 🤓💬 Read the full paper here: https://lnkd.in/gqRNqhw3 #SolarEnergy #RenewableTech #BiVO4 #Photovoltaics #Photoelectrochemistry #ResearchPublication #Sciencecommunity

For every 1℃ increase in temperature, the power generation efficiency of the solar cell will decrease. Decline 0.35%~0.5% For example, the stable output of a 580w solar panel is 580w at 25℃. Then if the temperature is 35℃, the output is 560w. According to laboratory measurements, for general crystalline silicon solar cells, the temperature influence coefficient γ is between -0.35%/℃ and -0.5%/℃, that is, above the standard test temperature, More detail in www.inkpv.com #solarpanel #solarpanelfactory
