“…However, one of the disadvantages of photovoltaics lies in their strong nonlinear behaviour as illustrated by the I-V (Current-Voltage) curve which demonstrates the characteristic behaviour of the output power, as shown in Fig. 6 [11], [12], [13]. This illustration is important, since the slope of the I-V curve varies between different types of photovoltaics [13].…”

Here, only one point exists in which the maximum amount of power can be obtained, referred as the maximum power point (MPP) [11], [12], [13]. The fill factor (FF) is suitable for analysing the slope of the I-V curve of photovoltaics and can be calculated as follows:…”

This paper discusses the possibilities to measure the amount of light with the help of portable devices such as mobile phones and tablets. Focus is directed to the accuracy of the ambient light sensor on smartphones in order to obtain the illuminance indoors and the solar radiation level outdoors. In general, information on the ambient conditions is vital to improve the performance of solar chargers. For example, if users are able to allocate beneficial locations to deploy solar chargers inside buildings, up to 100 times more energy can be gathered during the same periodic time. Similarly, under outdoor environmental conditions, solar modules can be aligned better towards the sun to increase the possible amount of output power. We analyse the accuracy of ambient light sensors which are available in today's low-cost and upper-class smartphones. Additionally, we present calibration strategies for ambient light sensors in order to minimise the error between conventional measurement equipment and mobile phones.

In this paper we discuss the alignment and system structures of photovoltaics on the roof of electric vehicles (EVs) and hybrid electric vehicles (HEVs). We focus on the interconnection of PV cells. In general, the position of photovoltaics on the roof of automobiles is crucial and has a strong impact on the photovoltaic (PV) output behaviour, in particular their output power level. We present strategies which allow the adaption of system structures according to changes in environmental conditions. As a result, we increase output performance levels by changing the interconnection of photovoltaics dynamically.
