  3. Silicon heterojunction (SHJ) technology can provide high solar cell efficiency and low cost in high volume manufacturing. Transparent conductive oxides (TCOs), a component in SHJ cells, can help achieve good conductivity and electrical contact with metals for transferring current. However, optimizing TCO layers in SHJ solar cells requires a tradeof...

  4. Spin torque oscillators (STOs) offer an innovative alternative to microwave power generation and energy efficient computing. However, both applications require phase locking of an array of STOs, which has so far been difficult to accomplish. Additionally, conventional STOs are difficult to couple electrically and magnetically, and they require a la...

  7. The vast quantity of solar panels in utility-scale solar farms makes detecting defective panels challenging. Solar farms may have upwards of five million solar modules and, to inspect them, maintenance staff must manually examine them, an often unreliable and straining approach. Power output of solar panels decreases when individual cells or module...

  8. Smart metal-organic frameworks (MOFs) are porous, crystalline materials made of metals bonded to organic molecules (ligands) that have changeable properties when introduced to external stimuli. Changing the minimum energy required to excite an electron into a conductive state (optical band gap energy) allows control of the conductivity. Most effort...

  9. Inverters are devices typically used in solar power generation systems to convert electric current to a more useful type, but are prone to failure and are the main cause of malfunction in solar power systems. Using transformer-less (TL) inverters is a desirable alternative because of their higher efficiency, lower size, and lower cost. However, TL ...

  10. During production of silicon solar cells, there is a large percentage of cells which do not meet quality requirements. These cells include broken, low-efficiency, and other defective cells, adding up to about 5% of all the cells produced. Although low-efficiency cells can be sold at discounted prices, they typically end up in landfills. These cells...
