High mobility transparent conducting oxide (HMTCO) materials (mobilityN60 cm2 V−1 s−1) have a high transmission over the visible to near infra redwavelength region with resistivity b2×10−4Ωcm.We investigate the application of HMTCO materials as transparent contacts for multi-junction and bifacial solar cells to increase the device NIR transmission. Using the HMTCO materials as front contacts significantly reduces absorption and reflection losses of the solar cells, from 850–1500 nm. The need to develop a low temperature process to prepare HMTCO materials as back contacts in semi-transparent solar cells is also emphasized.

Abstract

High mobility transparent conducting oxide (HMTCO) materials (mobilityN60 cm2 V−1 s−1) have a high transmission over the visible to near infra redwavelength region with resistivity b2×10−4Ωcm.We investigate the application of HMTCO materials as transparent contacts for multi-junction and bifacial solar cells to increase the device NIR transmission. Using the HMTCO materials as front contacts significantly reduces absorption and reflection losses of the solar cells, from 850–1500 nm. The need to develop a low temperature process to prepare HMTCO materials as back contacts in semi-transparent solar cells is also emphasized.
