Photocurrent

'The biggest limitation for conventional silicon is that it is blind in the infrared region of the spectrum and so this light available from the sun is not converted to photocurrent. ❋ Chemistry World (2010)

The radial geometry array also, as photocurrent and optical transmission measurements by Yang and Garrett revealed, greatly improves light trapping. ❋ Unknown (2010)

From comparative measurements of samples with Rhodamine B and CdSe/ZnS QDs it is established that PbS LSCs generate nearly twice the photocurrent in silicon cells than the other materials, achieving an integrated optical efficiency of 12.6%. ❋ Unknown (2010)

Unfortunately, as expected, they quickly succumbed to light-driven damage; within five hours, the level of the photocurrent dropped to half its peak value. ❋ Unknown (2010)

When exposed to light of the appropriate wavelength, a photocurrent was produced by the device. ❋ Unknown (2010)

The authors simply added a bit of detergent to the solution, and its ability to generate a photocurrent plunged, suggesting the detergent had disrupted photosystem II. ❋ Unknown (2010)

Creating tailored nanorod structures for hydrogen production from solar water splitting that maximize solar absorption and increase the ability to utilize the photocurrent using less expensive catalyst materials. ❋ Unknown (2009)

"The photocurrent density of plasma treated material was approximately 80 percent higher than that of the control electrodes."

In this cross-section of an organic photovoltaic cell, light passes through the upper layers (from top down, glass, indium tin dioxide, and thermoplastic) and generates a photocurrent in the polymer-fullerene layer. ❋ Unknown (2009)

The resultant structure gives the light-generated photocurrent more opportunities to reach the proper electrodes and reduces the accumulation of fullerenes at the film bottom, both of which could improve the photovoltaic's efficiency or lifetime. ❋ Unknown (2009)

The microscope, developed in Ginger's lab to record photocurrent, comes to a point just 10 to 20 nanometers across (a human hair is about 60,000 nanometers wide). ❋ Unknown (2009)
