Abstract :
The buried contact solar cell is being developed for use in the ENTECH 22×linear Fresnel concentrator system. The cell design is optimized for use with the actual nonuniform concentration profile expected from the ENTECH system and for use with prismatic covers to a eliminate grid line shadow loss. Under these conditions and maintaining a high sheet resistance for maximum current collection, the series resistance loss from the cell grid pattern is less than 5% of the generated cell power. Results of the initial fabrication experiments are reported. The results support the value of using prismatic covers to improve efficiency
