Purpose: The paper aims to determine the values of the main morphological characteristics of nanopatterns, which can be considered as the reference for use as surfaces of solar cells. Design/methodology/approach: The article uses an approach based on the definition of reference indicators of nanopatterns for solar cells by analysing the main parameters of solar cells and comparing them with the possible values of morphological parameters. Correlations of pore radius and visible wavelength, porosity and visible range, wavelength of de Broglie, nanopatterned layer thickness and charge carriers diffusion length, etc., are analysed. Compliance verification of morphological characteristics of nanopatterns with the specified criteria was performed on the example of porous silicon layers. Findings: The conducted research allowed to define the basic values of morphological parameters of porous nanopatterns, namely porousness, pore size (effective diameter), the thickness of the porous layer, and form factor. Reference ranges of morphological parameters of nanopatterns formed on the surface of semiconductors for applications in solar cells are established. Research limitations/implications: The article is devoted to the choice of optimal morphological characteristics of porous nanopatterns on the surface of semiconductors for solar cells. However, for solar cells, other types of nanopatterns can also be applied, for which it is also necessary to develop methods for selecting optimal parameters. Moreover, the prospect of research on this topic is to check the intrusion into a certain range of values of real nanopatterns formed on the surface of semiconductors. Practical implications: In the article the methodology allowing to choose optimal values of morphological parameters of nanopatterns for its application for solar cells is considered. Such studies are of great practical importance for the production of high-quality solar cells based on nanopatterned semiconductors. Originality/value: The article for the first time considers the choice of the nanopattern type and the ranges of morphological parameters in terms of quality assurance of the final product - the solar cell. It is determined that it is necessary to take into account such factors as porousness, pore size, thickness of the porous layer and roundness. A range of optimal values is selected for each of the indicators.

Parametry morfologiczne pian stałych wyznaczone zostały przy użyciu mikrotomografii komputerowej, mikroskopii optycznej oraz piknometrii helowej. Dla pierwszej z zaproponowanych technik sprawdzono wpływ wielkości woksela oraz metody binaryzacji obrazów na mierzone wielkości. Porównano wartości parametrów morfologicznych pian stałych otrzymane zaproponowanymi technikami oraz przedyskutowano ewentualne różnice.

Morphological parameters of the solid foams have been determined using computed microtomography, optical microscopy and helium pycnometry. For the first technique, impacts were studied of the voxel size and method of the image binarization on the measured parameters. Morphological parameters derived were compared and the differences discussed.

Praca poświęcona jest zagadnieniu opisu cech geometrycznych cząstki ciała stałego. Zaproponowano metodę opisu kształtu pojedynczej cząstki w języku parametrów erozji i penetracji jej powierzchni, skonstruowanych w oparciu o definicje podstawowych operacji elementarnych morfologii matematycznej. Wykorzystano w tym celu pojęcia dwóch morfologicznych operacji - dylatacji i erozji. Wprowadzono pojęcie projekcyjnych parametrów kształtu.

The work deals with the problem of solid particle surface geometry description. The method of single solid particle shape description was proposed. The method mentioned involves érosion and pénétration parameters. In order to define parameters mentioned - two morphological operations - dilatation and erosion were applied. Projective morphological shape parameters were introduced.
