TL;DR: In this article, basic limitations of single-junction and tandem p-n and p-i-n diodes are established from thermodynamic considerations on radiative recombination and semi-empirical considerations on the classical diode equations.

TL;DR: In this paper, the effect of substrate morphology on the growth and electrical properties of single-junction microcrystalline silicon cells is investigated, and it is shown that enhanced electrical properties are obtained when U-shaped substrates are used and the effect is universal, i.e. independent of the substrate or feature size.

TL;DR: This work presents a multiscale electrode architecture that allows it to achieve efficiencies as high as 14.1% with a thin-film silicon tandem solar cell employing only 3 μm of silicon.

TL;DR: In this paper, the use of a silicon oxide interlayer between the active area and the back contact of the cell permits in such cases to improve the electrical properties of the cells, and relative increases of up to 7.5% of fill factor and of 6.8% of conversion efficiency are shown for amorphous silicon cells, together with improved yield and low-illumination performance.

TL;DR: In this article, the imprinting of random square based pyramidal textures with micrometric scale at the air/glass interface of thin film silicon solar cells is presented as an efficient alternative to anti-reflective coatings to minimize reflection losses at the cell entrance.
