Abstract
The invention relates to a multicolor sensor with a plurality of diode functions comprising a succession of layers with p and n doped layers. Conductive transparent contact layers are thereby fitted. According to the invention, pin, nip, npin and/or pnip structures can be provided.
Claims6
A multicolor sensor comprising:
- a transparent first conductive layer at a light-incidence side of a stack;
- first layer sequence adjacent said first conductive layer and following said first conductive layer in a direction of travel of light through said stack, said first layer sequence forming part of said stack and constituting a first diode function absorptive to a low wavelength in said light;
- a transparent second conductive layer adjacent said first, layer sequence;
- a second layer sequence adjacent said second conductive layer and following said second conductive layer in said direction of travel, said second layer sequence forming part of said stack and constituting a second diode function absorptive to an intermediate wavelength in said light greater than said low wavelength;
- a transparent third conductive layer adjacent said second layer sequence;
- a third layer sequence adjacent said third conductive layer and following said third conductive layer in said direction of travel, said third layer sequence forming part of said stack and constituting a third diode function absorptive to a wavelength in said light greater than said intermediate wavelength;
- and
- a fourth conductive layer adjacent said third layer sequence whereby a three-color signal is obtainable simultaneously from said conductive layers.
