“…However, they are expensive due to not only the cost of silicon wafers but also the high temperatures required to fabricate p-n junctions [1,2]. C-Si heterojunction solar cells with an intrinsic hydrogenated amorphous silicon (a-Si:H) thin-film (HIT) also have been extensively studied and have achieved a high efficiency of 22-23% [3,4]. In general, low-pressure plasmaenhanced chemical vapour deposition (PE-CVD) and sputtering techniques are used for the deposition of a-Si:H and transparent conductive oxide (TCO) layers.…”

“…Here we introduce the partitioned linear Fresnel lens design and manufacturing of lenses for medium-CPV modules using HIT (Hetero-junction intrinsic thin layer) silicon solar cells which we are now developing with > 20 % efficiency [5]. Similar linear Fresnel lens is reported elsewhere, but essentially different from ours [6].…”

Abstract. We introduce the novel 50 50 mm 2 medium-CPV (Concentrated Photovoltaic) lens design in which linear type Fresnel patterns are formed for the efficient and uniform illumination of sunlight onto the 10 10 mm 2 HIT (Heterojunction intrinsic thin layer) silicon solar cells. We utilized LightTools illumination design tools and carried out optimization to obtain the optical efficiency up to 85~87 %. Lens fabrication is being carried and tested for the practical optical efficiency when integrated to develop CPV modules.

“…When a direct-band-gap photoactive material (such as gallium-arsenide) is used, parasitic absorption impinges on the photon recycling process and reduces the achievable voltage output [1]; whereas when indirect-band-gap photoactive material (such as silicon) is used, this parasitic absorption impinges on the current density output [2][3][4][5]. In the case of thin-film silicon technology, parasitic absorption due to non-active layer has been identified as a major limitation for present devices [6,7].…”

The role of front and back electrodes in parasitic absorption in thin-film solar cells

When it comes to parasitic absorption in thin-film silicon solar cells, most studies focus on one electrode only, most of the time the substrate (in n-i-p configuration) or superstrate (in p-i-n configuration). We investigate here simultaneously the influence of the absorption in both front and back electrodes on the current density of tandem micromorph solar cells in p-i-n configuration. We compare four possible combinations of front and back electrodes with two different doping levels, but identical sheet resistance and identical light-scattering properties. In the infrared part of the spectrum, parasitic absorption in the front or back electrode is shown to have a similar effect on the current generation in the cell, which is confirmed by modeling. By combining highly transparent front and back ZnO electrodes and high-quality silicon layers, a micromorph device with a stabilized efficiency of 11.75% is obtained.
