Scientists boost organic solar cell efficiency using polymer zwitterions
A research team based in China and the United States has developed electroactive polymer zwitterions to modify zinc oxide interlayers in organic solar cells. Their work was found to passivate defects in organic solar cells, helping to improve device performance and stability.
NREL researchers warn of unexpectedly high UV-induced degradation in n-type solar modules
A research team from the U.S. National Renewable Energy Laboratory has analyzed n-type modules deployed in a 3 MW commercial PV project in an effort to assess the high degradation rate reported by the plant owner. The scientists found that ultraviolet-induced degradation (UVID) was a major factor affecting the facility’s performance.
Scaling perovskite tandems’ U.S. prospects
Three US manufacturers actively working to commercialize their respective perovskite-silicon tandem technologies make the case for tandem modules. CubicPV, Caelux and Swift Solar argue a commercial future for perovskites is inevitable, and they tell pv magazine the current policy environment could work in the technology’s favor.

Finetuning 2D Dion-Jacobson perovskites for photovoltaic applications
Canadian and U.S. researchers have investigated applying pressure to a 2D hybrid organic-inorganic perovskite to tune the optical and electronic properties to suit photovoltaic applications, light emitting diodes or other semiconductor devices.
New deep learning tech for PV inverter fault diagnosis
A team of scientists at Georgia Southern University has combined both spatial and temporal attention mechanisms to develop a new approach for PV inverter fault detection. Training the new method on a dataset created in MATLAB/Simulink, the group has compared it to a series of other data-driven and statistical-based methods and has found accuracy reached 97.35%.
