Abstract
Methods and apparatus for the rapid and parallel synthesis of optoelectronic cell devices and for the high-throughput screening of such devices for useful properties are disclosed. The methods comprise the parallel synthesis of arrays of optoelectronic devices fabricated within an addressable sample-holding matrix. Each optoelectronic device is created and tested within an addressable sample-holder in the fabrication device.
Claims32
A method comprising:
- forming a plurality of optoelectronic devices, wherein forming comprises depositing particles of a precursor material in a precursor layer, and reacting the precursor material in one or more steps to form a photovoltaic active layer comprised of an inorganic semiconductor;
- wherein each optoelectronic device is located in an array at a uniquely addressable position in the array;
- wherein forming further comprises independently controlling reaction conditions at each uniquely addressable position.
