This paper reports on the fabrication of high‐eficiency back‐side contact silicon solar cells in large volume for the '93 World Solar Challenge. the cells were used exclusively on the winning car, the Dream, made by Honda R&D Company, Ltd. the cell efficiencies were between 20% and 22% (AMI.5G, 25°C) (G = global) and the average cell efficiency was greater than 21%. an important program of quality control was necessary to maintain a tight efficiency distribution and a high fabrication yield.

This paper reports the efficiency of bifacial silicon solar cells and mini-modules fabricated at SunPower Corp. The best cell has AMl.5G front efficiency of 21.9% and rear efficiency of 13.9%. The mini-modules, each containing 20 bifacial cetls, attain efficiency as high as the average efficiency of their individual cells. The best module has AM1.5G front efficiency of 20.66% and rear efficiency of 10.54%. Optical properties of the bifacial cells have also been measured and analyzed. The results show that bifacial cells, compared to monofacial cells, absorb less infrared light and thus they can operate at lower temperature in space.
