Numerous publications have set out recommendations for early childhood teachers on how to promote participation in their day-to-day activities. The present study considers the role of the environment in facilitating children’s participation through a visual environmental analysis, using photographs from two group environments in two different centres across three countries (Germany, New Zealand, and the USA). The analyses distinguished between environmental features of: transparency, structure, flexibility and responsivity, accessibility of materials, functional diversity, and representations of children in the environment. The findings demonstrate that a systematic approach to the analysis of physical environments can provide greater understanding about how environments may facilitate or constrain young children’s participation in early childhood centres. This study contributes to the methodological development for this field of analyses in early childhood education.

Transferring them onto textile fabrics would enable using DSSCs on large-scale textile architecture or for several textile-based stand-alone solutions, such as loading a mobile phone by a DSSC tent. For this approach, it is not only necessary to work with nontoxic and inexpensive materials, but also to create elastic and ideally even stretchable electrodes and other layers. Here we report on optimizing a conductive silicone rubber layer, filled with carbon black and graphite, on a viscose woven fabric to create a flexible counter electrode with inherent catalyst. Investigations of DSSCs with this coated textile, combined with a glass photo-electrode prepared with TiO2 and a natural anthocyanin dye, revealed effiencies up to the values gained with pure glass DSSCs.

DSSCs are known to function well in low light or diffuse light conditions. Therefore, they could be interesting for indoor use, where the ambient light may have different spectra. In DSSCs, the visible light is absorbed by a dye molecule. The efficiency is affected by the overlapping grade of the maxima in the dye absorption spectrum and in the illumi-nation spectrum, i.e. through an appropriate choice of dye, the efficiency can be max-imized for each illumination condition.

Opposite to silicon-based photovoltaics, DSSCs can be produced purely from non-toxic, inexpensive materials. Nevertheless, nowadays most research is performed aiming at increasing the efficiency of DSSCs based on (mostly toxic) ruthenium dyes or perovskites. In this paper, examinations include only non-toxic substances due to the planned subsequent use in textile fab-rics, i.e. to TiO2, graphite, iodine/tri-iodide as electrolyte and an anthocyanin dye. Dif-ferent application methods for the graphite layer of DSSCs were compared, focusing on such techniques which could also be applied on textile fabrics. A mixture of con-ductive silicone rubber and graphite powder resulted in the highest efficiencies, as compared to graphite pen, graphite spray, and coating with graphite flakes. In com-parison to DSSCs with a pencil-made graphite layer, the power density could be in-creased by a factor of 2 by the new composite material.

This led to a swift development of dye-sensitized so-lar cells (DSSCs). The highest efficiencies are achieved by cells which use synthetic ruthenium-based dyes; however, DSSCs can also be prepared from low-purity and nontoxic materials. Extracting anthocyanins from, e.g., fruit or commercially available tea offers an economic and ecological alternative to toxic dyes, while the solar cell ef-ficiency is significantly reduced. This article reports on the possibility of using antho-cyanin-based DSSCs under ambient light, which was modified by different grey and color filters. Dyes were tailored by modifying the pH value of the dye solution. While generally the lowest pH values resulted in the highest efficiencies, the performance of all DSSCs depended strongly on the light spectrum, for some color filters even favor-ing the original dye solution without pH modification.
