CHIP - Cost-efficient high-throughput ion-implantation for photovoltaicsIon implantation offers the possibility to implement a variety of novel and higher efficient solar cell concepts in cost efficient production sequences. Here the instrinsic directed nature of the ion implantation technology enables sigle side doping or even selctive doping structures by using masking schemes. As ion implantation process induced damage on the solar cell surface reduces its quality significantly, thermal post process annealing is required tob e included in the sequence. By varying the combination of a multitude of process parameters from ion implantation as well as annealing the final doping profile can be influended in great details and therefore adapted to the specific requirements of the respective solar cell. Within the framework of the CHIP project the partners Bosch Solar Energy AG, institute for solar energy research Hameln (IFSH) and the institute of electronic materials and devices (MBE) at Leibniz University Hannover performed experiments in order to gain deeper understanding of the ion implantation technology and its applicability for high efficiency solar cell manufacturing.Led by: Prof. Dr. sc. nat.

POLO - Smart formation of poly/mono-crystalline Si junctions using local doping techniquesThe further increase in the efficiency of industrial-type solar cells is limited by the recombination at the metal contacts. A promising approach to minimize this recombination is the use of junctions consisting of thin silicon dioxide capped by polycrystalline silicon (poly-Si) on top of crystalline silicon (c-Si).Led by: Prof. Dr. Robby PeibstYear: 2014Funding: Federal Ministry for Economic Affairs and Energy (BMWi)Duration: 3 Years
