摘要
在小型设备上实现了高达12.3%的效率。预计在不久的将来，通过改善现有设备的填充系数，小型设备的效率将超过14%。从长远来看，预计效率将达到16%-18%。已经实现了6w，面积约929 cm2的模块，有效面积效率超过8%(孔径效率为7.3%)。生产4平方英尺的CdS/CdTe模块的可行性已经证明，需要进一步努力以实现整体潜力。通过热循环和室外寿命测试，研究了封装设计的结构完整性。通过SERI户外可靠性和寿命测试实验室对子模块进行了超过270天的寿命测试，没有明显的退化。除了进一步优化材料和器件结构外，未来的模块产量还将通过改善沉积过程的均匀性，以及最大限度地减少因细胞分裂互连而导致的活性面积损失来增加。预计在20世纪90年代中期，组件产量将达到135w m - 2，长期将超过150w m - 2。
Efficiencies of up to 12.3% have been achieved on small devices. It is expected that 14% efficiency will be exceeded on small devices by improving the fill factors on the present devices in the reasonably near future. Efficiencies in the range 16%–18% are expected to be achieved in the longer term.
Modules of 6 W, approximately 929 cm2 in area with an active area efficiency of over 8% (aperture efficiency of 7.3%) have been achieved.
The feasibility of producing 4 ft2 modules of CdS/CdTe has been shown and requires further efforts in order to realize the overall potentials.
The structural integrity of the encapsulation design has been studied by thermal cycling and outdoor life testing. Submodules have been life tested for over 270 days with no observable degradation by the SERI Outdoor Reliability and Life Testing Laboratory.
In addition to further optimization of materials and device structure, module output in the future will be increased by an improvement in the uniformity of the deposition process, and by minimizing the loss of active area due to cell division interconnections. Module output is expected to attain 135 W m−2 in the mid 1990s and over 150 W m−2 in the long term.
