Crystalline Silicon Solar Cells In article number 2300250, Xu, Wei, Fu, and co-workers prepared self-assembled monolayer Ti3C2Tx MXene films utilized them as electron-selective contacts for dopant-free back-contact heterojunction silicon solar cells to reduce losses. A breakthrough power conversion efficiency of 16.46% is achieved by full-area rear contact without passivation. These results ope...

Recent progresses in liquid phase crystallization enabled the fabrication of thin wafer quality crystalline silicon layers on low-cost glass substrates enabling conversion efficiencies up to 12.1%. Because of its indirect band gap, a thin silicon absorber layer demands for efficient measures for light management. However, the combination of high quality crystalline silicon and light trapping st...

Optical characterization methods were applied to a series of microcrystalline silicon thin films and solar cells deposited by the very high frequency glow discharge technique. Bulk and surface light scattering effects were analyzed. A detailed theory for evaluation of the optical absorption coefficient a from transmittance, reflectance and absorptance ~with the help of constant photocurrent met...

Solar cells based on a heterojunction between crystalline silicon and the organic polymer PEDOT:PSS were fabricated at temperatures < 100oC by spin-coating. The Si/PEDOT interface blocks electrons in n-type silicon from moving to an anode and functions as a low-temperature alternative to diffused p-n junctions. Reverse recovery measurements were used to show that current in the device is primar...

Vertically aligned radial-junction solar cell designs offer potential improvements over planar geometries, as carrier generation occurs close to the junction for all absorption depths, but most production methods still require a single crystal substrate. Here, we report on the fabrication of such solar cells from polycrystalline, low purity (99.98%) p-type silicon starting material, formed into...

In our present work, five previously proposed sp(3) carbon crystals were suggested as silicon allotropes and their stabilities, electronic and optical properties were investigated using the first-principles method. We find that these allotropes with direct or quasi-direct band gaps in a range of 1.2-1.6 eV are very suitable for applications in thin-film solar cells. They display strong adsorpti...

We propose a design to confine light absorption in flat and ultra-thin amorphous silicon solar cells with a one-dimensional silver grating embedded in the front window of the cell. We show numerically that multi-resonant light trapping is achieved in both TE and TM polarizations. Each resonance is analyzed in detail and modeled by Fabry-Perot resonances or guided modes via grating coupling. Thi...
