Symposium EN11—Silicon for Photovoltaics
Silicon continues to dominate the photovoltaic market with increasing cell efficiencies and lower costs. To maintain this trend, sustained research in key and emerging areas is vital, including: (i) the understanding and mitigation of bulk absorber material defects; (ii) the development of carrier-selective, passivating contacts for high voltage devices; (iii) low-cost, low resistive metallization schemes; and (iv) the design of device architectures towards maximum current generation, which includes strategies aimed at improved utilization of the solar spectrum by combining silicon solar cells with complementary technologies such as perovskite and III-V solar cells for tandem solar cell fabrication. This symposium is focused on these themes, and especially welcomes scientific and technological contributions aimed at increasing the conversion efficiency and/or lowering the material and fabrication costs. Research contributions on silicon-enabled absorbing or passivating materials, new silicon allotropes and cross-cutting developments from other technologies are highly encouraged.
