Ultrathin (∼30 µm) flexible monolithic perovskite/silicon tandem solar cell

Herein, we report the first demonstration of the perovskite/silicon tandem solar cell based on flexible ultrathin silicon. We show that reducing the wafer thicknesses and feature sizes of the light-trapping textures can significantly improve the flexibility of silicon without sacrificing light utilization. In addition, the capping of the

Enhanced light absorption of ultrathin crystalline silicon solar cells

Abstract In contrast to traditional approach using Si nanotexture, we propose and investigate the light-trapping enhancement of ultrathin c-Si cells via the design of front nanostructured antireflective layer by using the finite-difference time-domain method, where four nanostructures of nanorod hole (NRH) arrays, nanosquare hole (NSH) arrays, inverted

Thus far, we have reported on the nanotexturing of ultra-thin monocrystalline Si substrates. Given the promising optical results, we now try to transfer them into a proof-of-concept IBC solar cell that can exploit the optical advantage of a bSi front surface in the material. In particular, we used 40 µm ultra-thin silicon substrates. Notice

Experimental and simulation study for ultrathin (∼100 μm) mono

A reduction in silicon material consumption in the photovoltaic industry is required for cost reduction. Using crystalline silicon wafers of less than 120 microns of thickness is a promising way for cost and material reduction in the solar cell production. The standard thickness of crystalline silicon solar cells is currently around 180 microns. If the wafers are

Solar Energy Materials and Solar Cells

Ultrathin monocrystalline silicon (mono-Si) wafers with thicknesses less than 100 μm have gained significant attention from the PV community, not only because of the decreased consumption of silicon materials but also because of their excellent flexural strength.

Ultrathin crystalline silicon solar cells on glass substrates

We fabricate thin crystalline silicon solar cells with a minority carrier diffusion length of 0.6±0.2 μm by direct high-temperature chemical vapor deposition on glass substrates. This small diffusion length does not allow high cell efficiencies with conventional cell designs. We propose a new cell design that utilizes submicron thin silicon layers to compensate for low minority carrier

Nano-Photonic Structures for Light Trapping in Ultra-Thin

Thick wafer-silicon is the dominant solar cell technology. It is of great interest to develop ultra-thin solar cells that can reduce materials usage, but still achieve acceptable performance and high solar absorption. Accordingly, we developed a highly absorbing ultra-thin crystalline Si based solar cell architecture using periodically patterned front and rear dielectric nanocone arrays

The ultrathin film of 2PACz with phosphate groups can establish strong and stable P–O–Si bonds on the silicon surface. Meanwhile, like 2PACz, a uniform ultrathin film with a carbazole function group can offer electron-localizing and thus hole-selective properties, which provides ideas for studying dopant-free silicon solar cells.
