Abstract
A new, low cost solar cell - based on work done by Professor Grätzel - was evaluated for power generation applications. The main effort at ABB was directed towards the development of cells with high efficiencies and towards the development of production methods for the electrodes. Using optimized electrodes made by screen-printing techniques, an efficiency of 9.4% could be obtained for small electrodes (0.5 cm2). Lifetimes of more than 10 months without degradation could be achieved at the EPF Lausanne using this type of cell.
