Abstract
Photovoltaic devices and methods of manufacture are provided. In an embodiment, the devices comprise a micro-crystal silicon cell having an amorphous silicon layer formed on the micro-crystal cell.
Claims20
A photovoltaic device, comprising:
- a micro-crystal, thin film silicon solar cell comprising an absorber layer comprising micro-crystal silicon having a bandgap;
- and
- a window layer adjacent the absorber layer, the window layer comprising a material with a higher bandgap than the micro-crystal silicon.
A method for manufacturing a photovoltaic cell, comprising:
- forming a transparent conductive oxide layer on a substrate;
- depositing a doped window layer having a bandgap;
- depositing a base including a first doped micro-crystal silicon layer having a bandgap lower than the window layer bandgap to provide an emitter;
- and
- forming a back contact.
