Crystalline photovoltaic cell research, status, and future direction.

摘要

Sandia National Laboratories has overall DOE PV Program responsibility for research and development of one-sun crystalline silicon and concentrator cell technology for both crystalline silicon and III-V materials. The goal of this research is to establish the technology base from which US industry can choose options for commercialization. This research is accomplished through a combination of university, industry, and national laboratory efforts. The Photovoltaic Device Fabrication Laboratory (PDFL) and the Photovoltaic Device Measurements Laboratory (PDML) are both operated as part of this effort. The PDFL provides continuity for cell processing research and an essential technology transfer link between universities and industry. Cell measurements and performance analysis are conducted in the PDML. Cell modeling and studies of basic cell physics are also important aspects of this research. In this paper the status of crystalline cell research is reviewed, recent results are presented, and future research directions are outlined. Future directions include an initiative to develop reliable, high-efficiency, cost effective concentrator cells in US industry. Collaborative research into production engineering will be an important aspect of this concentrator initiative. Production oriented research in cooperation with the US one-sun crystalline silicon industry will also be the future direction of the one-sun crystalline cell project. 30 refs.
