Flexible and high-efficiency Sb2S3/solid carrier solar cell at low light intensity

Abstract

Producing green and efficient energy sources is a major challenge. As a consequence, the use of photovoltaic devices for conversion of light into electricity is growing worldwide. A lot of effort had been invested to create high-efficient solar cells, but their durability, stability, flexibility and efficiency at low light intensities are still unexplored. Here, we built a flexible solar cell made of p-doped, amorphized a-undoped and n-doped Sb 2 S 3 solid carrier loaded with electrolyte. Indium tin oxide glass was the working electrode, and aluminium was the counter electrode. Every (p-a-n) flexible Sb 2 S 3 /solid carrier layers were obtained using a cheap casting/solvent evaporation technique, from a blend consisted of chitosan, polyethylene glycol and electrolyte containing 0.5 M potassium iodide and 0.05 M iodine, and corresponding synthesized amorphized a-undoped and p and n-doped Sb 2 S 3 semiconductor.Results show that flexible Sb 2 S 3 solar cell possesses good stability and efficiency of about 10% at 5% sun. Overall, our findings demonstrate for the first time that flexible solar cell can be made and used for low light intensity applications.

The influence of the water flow lens system on the operating characteristics of monocrystalline and amorphous Si‐solar cells for outdoor and indoor use: The photovoltaic improvement

“…On the other hand, the truth is that in the indoor environment, the spectral composition deviates greatly from AM 1.5, which can be seen in Figure 1b, 16 where the deviations in their spectra are more than evident. In all our previous publications, 15–17,57–62 it has been seen that even tiny differences in the spectrum have quite a pronounced and improved influence, primarily on current, voltage, and efficiency, and these observations included our designed Sb 2 S 3 ‐based, dye‐sensitized, and silicon cells. As a result, the different spectra of each of these lamps, which “well simulate outdoor radiation,” can have a significant impact on photovoltaic performance.…”

Present Status and Future Perspective of Antimony Chalcogenide (Sb2X3) Photovoltaics

“…Lojpur et al in 2018 demonstrated a p-i-n diode structure based flexible Sb 2 S 3 solar cell, inspired by an a-Si solar cell architecture. The device employed light facing Cu:Sb 2 S 3 as the p-layer, undoped/amorphized Sb 2 S 3 as the sandwiched layer, and Se:Sb 2 S 3 as the n-layer.…”

“…Building integrated photovoltaics (BIPVs), semitransparent electronics, wearable electronics, and flextronics are other key areas, where Sb 2 X 3 PVs can possibly outperform other PV technologies . Sb 2 S 3 exhibits suitable E g (∼1.8 eV), nontoxicity, long-term stability, and excellent low-light harvesting; thus, it is well suited for standalone IPVs . With a slight improvement in PCE, the Sb 2 S 3 PV might be viable replacement for the a-Si PV in powering devices that require very low power, e.g., pocket calculators and wrist watches.…”

Sb 2 Se 3 , with narrow E g (∼1.1 eV), is a promising bottom cell material, in tandem solar cells.…”

Flexible Substrate‐Structured Sb2S3 Solar Cells with Back Interface Selenization

“…[ 18–20 ] While there are few reports on flexible Sb 2 S 3 solar cells. [ 21 ] Because of the high conductivity and bendability, the Mo foils can be directly used as electrodes and opaque substrates, which are beneficial to the construction of flexible substrate‐structured solar cells.…”
