An overview of the selected current research focuses of Laser Chemical Processing (LCP) technology at Fraunhofer ISE is given. The efforts to support the industrialization phase of the LCP technology include: (i) the processing of large-area solar cells, (ii) improving the uniformity of the laser doping, (iii) reducing the process cost by applying low-cost doping mediums and by eliminating the need of neutralization of the waste chemicals, and (iv) developing a LCP boron doping process, which is very attractive for the formation of the local back surface field for the p-type cells and for the formation of selective emitter for n-type solar cells.
