The discovery of British researchers may promote the evolution of photovoltaics

Scientists at Warwick University in the United Kingdom have discovered a way to change the structure of semiconductors at the nanoscale, which can increase the cell efficiency of several materials beyond theoretical limits.

The research team uses the conductive tip of the AFM device to compress the semiconductor into a new shape.

Scientists call this discovery the "flexible photovoltaic effect," which can change the single crystal of a semiconductor material and release more energy from the solar cell, so that they exhibit a photovoltaic effect.

In some types of semiconductors, there is an imperfect symmetry around the center point, which can produce a voltage greater than the bandgap of the material, making the conversion efficiency of the material very low. But scientists at the Physics Department at Warwick University have discovered a way to double the number of materials and change their structure so that they exhibit the photovoltaic effect.

Researchers studied barium titanate, titanium dioxide, and silicon crystals and found that all three crystals deformed and exhibited photovoltaic effects.

There are several advantages to expanding the range of materials that can benefit from the photovoltaic effect: there is no need to form any kind of kink; any semiconductor with better light absorption can be selected for solar cells, and finally, thermodynamics that can overcome power conversion efficiency The limit is the so-called Shockley Queisser limit.
