Manufacturing Technologies for Photovoltaics and Possible Means of Their Development in Russia (Review): Part 2. Modification of Production Technologies for Photoelectric Converters, Development of Contact Structures, and Choice of Promising Technologies for Expansion of FEC Production in Russia

摘要

As the development of the first part of the review of modern industrial technologies for manufacture of photoelectric converters (PECs) of solar power, the present paper considers modifications of technologies for manufacture of PECs, including various thin-film techniques. Main tendencies in the advancement of contact structures of PECs are described. Formulation and substantiation are made for promising, in the authors'opinion, lines of the development of industry of PECs in Russia based on the upcoming implementation of 1.5 GW network photovoltaic power plants to 2020, which are developed with the national support under conditions of the fulfillment of rigid requirements to manufacture localization. As the most prospective technology for development of the competitive manufacture of photoelectric converters subject to the Russian scientific and engineering groundwork, the authors recommend the technology based on single-crystal silicon of the n type with the passivation of the frontal and rear sides and symmetrical contacts (n-PASHa), which provides the possibility to produce double-faced solar modules also.
