  Incorporating multifunctionality along with the spin-related phenomenon in a
single device is of great interest for the development of next generation
spintronic devices. One of these challenges is to couple the photo-response of
the device together with its magneto-response to exploit the multifunctional
operation at room temperature. Here, the multifunctional operation of a single
layer p-type molecular spin valve is presented, where the device shows a
photovoltaic effect at the room temperature on a transparent glass substrate.
The generated photovoltage is almost three times larger than the applied bias
to the device which facilitates the modulation of the magnetic response of the
device both with bias and light. It is observed that the photovoltage
modulation with light and magnetic field is linear with the light intensity.
The device shows an increase in power conversion efficiency under magnetic
field, an ability to invert the current with magnetic field and under certain
conditions it can act as a spin-photodetector with zero power consumption in
the standby mode. The room temperature exploitation of the interplay among
light, bias and magnetic field in the single device with a p-type molecule
opens a way towards more complex and efficient operation of a complete
spin-photovoltaic cell.
