... • We measured that two shift registers operate at bias current as low as ~0.14 mA. It means one shift register consumes ~0.07 mA or 3.5 x kBTln2! • This figure is still above 0.02 mA thermodynamic threshold. But scaling of power dissipated in best CMOS gates (about 1.7.106 kBTln2) converts, say, 1 m ...

... our work. We believe this is because our annealing process is relative fast without any dwell time, therefore, there is no sufficient time for the crystallization. The calcined WO3 nanofibers were then gently mechanically ground in order to maintain their fibrous morphology. There is no differences ...

Shockley–Queisser limit



In physics, the Shockley–Queisser limit or detailed balance limit refers to the maximum theoretical efficiency of a solar cell using a p-n junction to collect power from the cell. It was first calculated by William Shockley and Hans Queisser at Shockley Semiconductor in 1961. The limit is one of the most fundamental to solar energy production, and is considered to be one of the most important contributions in the field.The limit places maximum solar conversion efficiency around 33.7% assuming a single p-n junction with a band gap of 1.34 eV (using an AM 1.5 solar spectrum). That is, of all the power contained in sunlight falling on an ideal solar cell (about 1000 W/m²), only 33.7% of that could ever be turned into electricity (337 W/m²). The most popular solar cell material, silicon, has a less favourable band gap of 1.1 eV, resulting in a maximum efficiency of 33.3%. Modern commercial mono-crystalline solar cells produce about 24% conversion efficiency, the losses due largely to practical concerns like reflection off the front surface and light blockage from the thin wires on its surface.The Shockley–Queisser limit only applies to cells with a single p-n junction; cells with multiple layers can outperform this limit. In the extreme, with an infinite number of layers, the corresponding limit is 86% using concentrated sunlight.
