Panasonic unveils 410 W solar panel with 22.2% efficiency
The new heterojunction module series is compatible with Panasonic’s Evervolt battery and has a power output ranging from 400 to 410 W. It also features a temperature coefficient of -0.26% per degree Celsius.
Perovskite ink for flexible solar panels
Developed by a Canadian start-up, Solar Ink can be used to create standalone perovskite solar modules or it can be combined with existing solar modules in a tandem configuration. It can be coated on both flexible and rigid substrates, resulting in translucent solar cells which, in turn, can be used to produce flexible and light modules for application in solar windows and vehicle-integrated photovoltaics.
Modeling method for agrivoltaics in greenhouses
Spanish researchers have developed a new modeling technique to assess the performance of semi-transparent PV systems for greenhouses. Their novel approach considers the broadband and spectral content of the irradiance, the solar cell technology and its performance metrics, and the relationship between the photosynthetic rate and the effective photon flux that falls on the crops.
