Summary: Transparent photovoltaics (TPVs) have shown high efficiency and color tunability, but challenges such as device size and stability need to be addressed. A new bifacial color-tunable (BCT) TPV using indium tin oxide (ITO) thickness tuning has been demonstrated. Batch production with dry plasma fabrication process and efficiency improvement with various background colors show promise for building-integrated photovoltaics (BIPV) applications.

Summary: This study analyzes the albedo dependence of the bifacial gain losses in bifacial PV modules due to inherent partial shading caused by rear-side support structures. The results demonstrate that the bifacial gain decreases nonlinearly at high albedo when the beam is closely attached to the rear side of the module. The study also identifies the mismatch loss caused by each part of the module's support structure.

Summary: This paper studied the influence of rear pyramid morphologies with different slope angles on the optical and electrical properties of bi-PERC solar cells. The results showed that a smoother rear surface was favorable for rear passivation but unfavorable for rear-side light trapping. Rear surface morphologies also influenced the front-side light trapping. The highest front-side average efficiency of 22.86% was achieved using a modified acidic polishing process.

Summary: This study presents a methodology and dataset for examining compound wind and solar energy droughts, as well as the first standardized benchmark of energy droughts across the Continental United States (CONUS) for a 2020 infrastructure. The results show that compound wind and solar droughts have distinct spatial and temporal patterns across the CONUS, and the characteristics of energy droughts are regional. The study also finds that compound high load events occur more often during compound wind and solar droughts than expected.
