Abstract
Results of further investigation into original concept of charge pumps in the structure of photoelectric cells show that charge pumps are formed due to the formation of spatial defect−dopant complexes which produce a qualitative change in the transport mechanism of light generated charges at the base of the solar cell. For the first time a large scale charge pump manufacturing process has been offered. This process involves a non−thermal or «cold» photon annealing and uses standard photon annealing equipment. The photon annealing effect is achieved by using an original photomask (removable). The mask provides an annealing pattern with multiple light sources and heat insulation of the target wafer. This process is called local photon annealing (LPA). Due to its efficiency and simplicity the process does not require significant industrial investment. Experimental results show that it is possible to increase short circuit current and maximum power output of a solar cell with the use of the LPA technique. Experimental solar cell samples have been chosen from different manufacturers.
