Effects during the cathode polarization of porous silicon.

The large inner surface of porous silicon (pSi) not only provides unique opportunities for introducing various foreign materials into the open pores, but is also responsible for a lot of processes during the pSi cathode polarization. PSi surface and contact effects are considered in the article. The space charge layer induced by both the surface states and the double electrical layer in the solution is shown to have a decisive influence on the electrical conductivity of the silicon skeleton in the pSi layer.

Enhancing the stability and efficiency of carbon-based perovskite solar cell performance with ZrO-decorated rGO nanosheets in a mesoporous TiO electron-transport layer.

Improving the role of electron-transport layers (ETLs) in carbon-based perovskite solar cells (CPSCs) is a promising method to increase their photovoltaic efficiency.
