“…We also found that device annealing at a higher temperature of 400 • C also results in low device performance due to the decreased V oc and FF. This may be attributed to the enlarged voids and oxidation of CdTe at high temperatures, which is consistent with the previous report [12]. The solar cells with the ZnSe NCs buffer layer annealed at 370 • C exhibits the best device performance, which includes a J sc of 11.94 mA/cm 2 , a V oc of 0.63 V, a FF of 40.79%, and a PCE of 3.07%.…”

“…Therefore, the device with ligand treatment will show less current leaking. It was reported in our previous work that CdTe NC solar cells with efficiency as high as 5.14% are attained with device configuration of ITO/ZnO/CdS/CdTe/MoOx/Au [12]. Comparing these two devices, the low PCE obtained in the ZnSe NC device is mainly attributed to the low J sc (13.55 mA/cm 2 to 17.26 mA/cm 2 for CdS device) and FF (47.33% to 52.84% for CdS device).…”

“…CdTe possesses an idea bandgap of~1.45 eV and a large absorption coefficient (>10 4 /cm in the visible region), which are promising with regard to achieving impressive power conversion efficiency (PCE). Nowadays, CdTe thin-film solar cells with efficiency >22% has been realized by optimizing the fabricating techniques, while other thin-film solar cells such as CuIn x Ga (1−x) Se 2 (CIGS) or perovskite with efficiency up to 23% are also realized, which is prospective for low-cost and efficient solar cell products [12]. By contrast, with the development of NC thin film treatment technics and device structure design, the PCE of solution-processed CdTe…”

Abstract:The CdTe nanocrystal (NC) is an outstanding, low-cost photovoltaic material for highly efficient solution-processed thin-film solar cells. Currently, most CdTe NC thin-film solar cells are based on CdSe, ZnO, or CdS buffer layers. In this study, a wide bandgap and Cd-free ZnSe NC is introduced for the first time as the buffer layer for all solution-processed CdTe/ZnSe NC hetero-junction thin-film solar cells with a configuration of ITO/ZnO/ZnSe/CdTe/MoOx/Au. The dependence of the thickness of the ZnSe NC film, the annealing temperature and the chemical treatment on the performance of NC solar cells are investigated and discussed in detail. We further develop a ligand-exchanging strategy that involves 1,2-ethanedithiol (EDT) during the fabrication of ZnSe NC film. An improved power conversion efficiency (PCE) of 3.58% is obtained, which is increased by 16.6% when compared to a device without the EDT treatment. We believe that using ZnSe NC as the buffer layer holds the potential for developing high-efficiency, low cost, and stable CdTe NC-based solar cells.

“…For silicon heterojunction (SHJ) solar cells, outstanding efficiencies of 26.7% [2,3] using an interdigitated backcontact (IBC) configuration and 25.1% [4] using a both-sides contacted (BSC) configuration are reported. In the BSC cell design, stacks of intrinsic and doped hydrogenated amorphous silicon (a-Si) layers on both sides of textured ntype silicon wafers are used to form carrier-selective heterojunctions that exhibit excellent passivation properties [5,6].…”

“…Several studies of perovskite solar modules have already been reported and, currently, the maximum conversion efficiency is reported to be 16.0% with an aperture area of 16.29 cm. 2,26) However, there is a large divergence of performance between single cells and modules. [27][28][29] More research on perovskite solar modules thus appears to be necessary.…”

We have been working on the fabrication of practical perovskite solar modules using an existing thin-film solar module patterning technology. Patterning processes were applied using laser scribing and mechanical scribing on a glass/F-doped SnO 2 (FTO)/compact TiO 2 (c-TiO 2 )/mesoTiO 2 /CH 3 NH 3 PbI 3 /2,2$,7,7$-tetrakis(N,N-di-p-methoxyphenylamine)-9,9$-spirobifluorene/Au structure. However, TiO 2 remained in the FTO-Au junction at the cell connection part: this appeared to create a series resistance that degraded the performance of the module. UV laser treatment was examined for application to the cell connection part to minimize this resistance. The results showed that the resistivity of the cell connection part, which was conventionally 0.26 Ω&cm 2 , was reduced to 0.1 Ω&cm 2 by this laser treatment. We designed the solar module based on the value of a contact resistivity of 0.1 Ω&cm 2 and the current-voltage curve of a small single cell. As a result of prototyping solar cell modules (35 cells in series) with an aperture area of 354 cm 2 on a 203 ' 203 mm 2 glass substrate, a module efficiency of 12.6% was achieved. There appears to be no serious impediment to the fabrication of the perovskite solar modules.
