It has only recently become known that two parallel systems of blood formation exist in the body, originating from different ...

WASHINGTON, Sept. 27, 2022 – Large obstacles, like clouds and buildings, can block sunlight from reaching solar cells, but smaller sources, such as dust and leaves, can also create similar problems.

Studies on the impact of panel shading on PV system output have long focused on large modules. Now, Chinese researchers are shifting the focus to single cells and two cells connected in series or in ...

Scientists from South Korea have designed new photovoltaic modules with both rectangular and triangular shapes and solar cells connected in parallel, which they said have higher partial-shading ...

Two solar cells connected in parallel (left) and in series (right) with an obstacle creating shade (brown). Shady conditions caused more power loss in series systems. Journalists may use this image ...

Many readers will have at some time or another built their own lithium-ion battery packs, whether they are using tiny cells or the huge ones found in automotive packs. A popular choice it to salvage ...

Shanghai researchers are exploring different conditions that could impact solar cell performance. The results have been published by the American Institute of Physics Journal of Renewable and ...

Ultracapacitors have a relatively low operating voltage so multiple cells must be connected in series to allow higher operating voltages. Now, a flat ultracapacitor enables smaller size ...
