> 16% Efficiency for Single-Junction Organic Solar Cells

The J-V characteristics for OSCs based on P2F-EHp:BTPT-4F and P2F-EHp:BTPTT-4F; the chemical structures of active layer components.

As a promising technology for renewable energy, organic solar cells (OSCs) have attracted particular interest from both industrial and academic communities. One of the main challenges to promote practical applications of OSCs is their less competitive power conversion efficiency than that of the counterpart

My Battery is Getting Low and it is Getting Dark
These were supposedly the last words sent back from Mars by the Opportunity rover. As we all know, machines don’t really communicate with such clarity and emotion, but it seemed a fitting farewell, and actually pretty well-deserved after seeing out its original mission objective of 90 days operation by over

Two Steps to High Voltages

Click image to enlarge

Figure 1. Boost topology for generating a high voltage from a low voltage

If a high voltage needs to be generated from a low voltage, a boost converter can be used. This represents one of the three elementary switching regulator topologies and requires only two switches, an inductor, and input and output capacitors. Besides the boost converter, the other basic topologies are the buck

Wide Bandgap Semiconductors and Packaging - it’s happening

Kevin Parmenter, Field Applications Manger, Taiwan Semiconductor

The promise of wide bandgap semiconductors (WBG) are higher switching frequency and higher operating temperatures perhaps smaller sizes, greater efficiencies and perhaps higher reliability, less size, less cooling – no fans for example, smaller heatsinks, smaller capacitors, less weight and overall better
