“…Foreign inclusions are measured with any measuring tool that provides a measurement error of no more than 0,1mm. Block glass haze inhomogeneity , craters, and extrusion glass bleed are determined by comparison with a duly approved control [15,18]. The length and width of glass sheets are measured with any measuring toolthat provides a measurement error of not more than 1 мм.…”

“…Therefore, the calculation of such lamps is important for obtaining diffusers that are not only successful in shape, but rational in terms of lighting technology. The mechanical properties determine the materials from each other when a force is applied to the material, usually related to the elastic and plastic behavior for the composite material [14][15][16].…”

Lighting a room may work successfully or break the room illumination. May frequently feel undesirable when the selected lights don’t suit the area or the purpose of the room. The aim of this article focusing on optimization the light illumination and fabricating lightening material from different polymer such as polystyrene and polycarbonate that work as perfect reflector for LED. Optical properties of the luminaire efficiency were studied for different lighting glasses and lighting parameters of LED lamps (SB), (SBPT), (SBS), (SE) and (SEP) were calculated after test. Also, the magnitude of absorption, transmission and reflection were calculated for each lighting polymer glasses that fabricated, and the resultant lighting glass showed an excellent reflection property for UV visible test. The mechanical properties of impact strength were calculated and showed good resistivity to fracture better than raw materials. Based on the results and as a conclusion indicates that, if the corrugated edge of lighting polymer glass is directed into the luminaire body, then the efficiency is insignificant, but still increases and for the spectral transmittance depends not only on the composition of the lighting glass, but also on the geometry of the surface on which the light falls.

“…In this project, the evolution of J-V parameters is performed to understand the degradation of conventional polymeric cells, using a copolymer called PTB7:PC 70 BM as the active layer. Similar materials or structures have been studied in previous works, achieving promising results [15,16] and making it interesting to investigate other variations. The behavior of the cells is studied under 1000 lux artificial LED 2700 K light, following the consensus stability testing protocols for organic photovoltaic materials and devices [17].…”

In this study, we analyze the degradation behavior of conventional polymeric solar cells (PSCs) under constant indoor light illumination. A LED lamp with a color temperature of 2700 K, was used for the indoor light illumination conditions. We compare the results obtained with encapsulated and non-encapsulated devices. The performance of the PTB7:PC70BM-based cell showed an initial maximum power conversion efficiency (PCE) of 12.0% under the luminance of 1000 lux and maximum power density (MPP) of 45.7 μW/cm2. The work describes the results of the measurements and analysis of the degradation process, performed by a current density – voltage (J–V) characteristic curve study under LED light. The analyzed performance parameters were PCE, short circuit current density (JSC), open-circuit voltage (VOC) and fill factor (FF). The PCE of encapsulated devices remained above 80% of the initial value after 624 h.

“…The parameters used in the model are adjusted to describe the perovskite PV behavior. After considering that the work of Torimtubun et al [15] and Cheng et al [14] employed 1000 lux of the LED (color temperature 2700 K) and 1000 lux of fluorescent light as an indoor light source, respectively, we chose to focus on an indoor light level of 1000 lux as well as 1 sun condition for comparison in this study.…”

The performance of perovskite solar cells (PSCs) has been improved throughout the years. These photovoltaic (PV) cells can be used to power Internet of Things (IoT) devices for indoor applications. A perovskite PV energy harvesting system with a stand-by battery that continuously powers an IoT device is developed in this work. The battery is required to complement the PSCs when the latter have difficulties in power delivery during low or no irradiance. The performance of the energy harvesting circuit as well as the battery charge and discharge scenarios are investigated. Voltage matching between the PSC and the battery is achieved by a boost converter. The PSC energy harvesting system uses fractional open-circuit voltage (FOCV) based maximum power point tracking (MPPT), which utilizes a Sample and Hold (S&H) circuit. The FOCV technique is based on a comparison of the perovskite PV open circuit voltages and the maximum power points. For each irradiance level, the maximum power point is unique, and this work uses a light-dependent resistor (LDR) to adjust the scaling constant in MPPT. Case studies include various scenarios under 1000 lux fluorescent light and 1 sun irradiance as well as a consideration of different battery states.
