摘要：

Bifacial solar modules are expected to increase their market share in the coming years. To date, most bifacial cells in production and under research are realized on n-type silicon substrates. However, p-type silicon has been dominating photovoltaic industry, partly due to its lower cost. In this work, we present an approach to combine bifacial applications with the industrial p-type passivated emitter and rear (PERC) structure: a bifacial PERC cell (biPERC). Simulation results are presented that showcase a high potential for bifacial gains of the biPERC cell. First experimental results of the biPERC concept on large-area multicrystalline silicon substrates yield a monofacial efficiency of 17.8%. The biPERC cell, therefore, is an easy-to-apply modification to a PERC route and enables higher output powers due to bifacial applicability. (C) 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim
