“…Coumarin dyes were also used as sensitizers with reported efficiency of 7.6% (Wang et al, 2007). The efficiency of DSSCs mainly depends on the absorption spectrum of the dye being used as photosensitizer and the electron transfer activity to the electrode (Dey et al, 2016). Anthocyanins from a variety of plants gave various photo-sensitizing performances.…”

Six natural dyes D1-D6 were extracted from various parts of Hibiscus rosa sinesis, Brassica oleracea, Celosia argentea, Rosa damascena, Rosa macdub (red and yellow) by maceration with ethanol for 24 hours for dyesensitized solar cells. Their photophysical, electrochemical and photovoltaic studies were carried out. UV-Vis absorption spectra of the dyes D1-D6 showed two distinct bands i.e. π -π* and ICT band. Out of all the extracted dyes, the dye D1 gave best absorption of ICT band at λmax 534 nm. Cyclic voltammetry of the dyes D1-D6 was carried out which revealed the distinct oxidation and reduction peaks in D1 and D2 dyes while in other dyes these peaks were weak. The photovoltaic performance of the dyes D1-D6 was also measured by making sandwich type DSSCs. Their J-V curves showed open circuit voltage values of the dyes were 0.36V, 0.37V, 0.36V, 0.34V, 0.34V, 0.39V and short circuit current density values are 5.48 mA/cm 2 , 5.69 mA/cm 2 , 1.71 mA/cm 2 , 3.99 mA/cm 2 , 2.71 mA/cm 2 and 5.18 mA/cm 2 respectively. The best sunlight to energy conversion efficiency was obtained from D1 dye which has better UV absorption and it gave higher short circuit current density which leads to highest efficiency. Other dyes gave the efficiency in the following order D2=0.9% > D6=0.8% > D4=0.5% > D5=0.3% > D3=0.2%.

“…Seko's group reported that the presence of PbI 2 in perovskite material reduces the hysteresis effect, ionic migration [7]. Although perovskite solar cells have attained high efficiency within a short period, it still faces some obstacles such as ionic migration [8][9][10], hysteresis [11][12], heavy metal lead [13][14][15][16], light soaking [17], etc.…”

A mini review of recent strategies towards stable nano-structure perovskite solar cell fabrication

Organic-inorganic perovskite solar cells (PSC) are drawing interest towards photovoltaic device fabrications due to low raw materials cost, easy room temperature fabrications, and exhibiting excellent tunable optoelectronic properties. Power conversion efficiency increased dramatically in the last few years despite challenges like instability in moisture and high ambient temperature conditions. However, techniques employed like encapsulation used to reduce perovskite degradation rate, long-term stability still an issue for commercial scale-up. Most of the perovskite materials, more precisely halide perovskites, are affected by the ambient humid conditions. In this present study, we explore the recent development of different strategies to fabricate moisture-resistant stable perovskite solar cell fabrication. This review discusses the structural influence on the stability of PSC.

Luminescent solar concentrators (LSCs) appear as photovoltaic (PV) complementary devices to overcome the mismatch between the Si-based PV cells response and the solar spectrum, with the major advantage of permitting PV urban integration. Challenges for the luminescent layer include the use of abundant and sustainable natural organic molecules. Here, LSCs composed of a glass container and based on bundles of cylindrical hollow-core plastic optical fibres (POFs) are presented. The glass container and the fibres' hollow-core were filled with aqueous solutions at different concentrations of R-phycoerythrin (R-PE), which is a phycobiliprotein, extracted from Gracilaria sp. algae. The R-PE solutions absorb in the UV/visible spectral range (300-550 nm) and convert this radiation into red-emission (550-700 nm) with a maximum absolute quantum yield of 0.39. In this work, LSCs with distinct geometries are reported, in which the R-PE emission yields optical conversion efficiency values up to 6.88% and 4.74% for a planar device and for a bundle of cylindrical LSCs, respectively, which are the largest values known for liquid-based LCSs using sustainable emitting centres. Moreover, the coupling of the LSCs to commercial Si-based PV devices yielded power conversion efficiency values of to 0.27% (planar) and 23.0310 -3 %, (bundle). These values illustrate the potential of this approach for the development of natural-based LSCs meeting the requirements of reliable, sustainable and competitive energy systems.
