Properties of a bio-photovoltaic nano-device
Journal article, 2008
Properties of an on-chip photovoltaic nanodevice are demonstrated. The dyes comprise green florescent proteins
(GFP). Dependence of recently reported zero external potential bias (ZEPB) photocurrent (I) on temperature,
power, and wavelength (λ) is shown. Correlation between UV-vis spectrum of the GFP and the ZEPB I(λ)
of the device is reported. The temperature dependence suggests the ZEPB photocurrent to reflect a liquid
crystal type ordering where the current declines monotonically with increasing temperature. The influence of
an external bias on the photocurrent is demonstrated. The resulting light-induced current is analyzed in terms
of resistive and quantum mechanical contributions.
