“…The resulting generation density of excitons can then be used as input for the electrical description of the device. Optical modeling has been done for both bilayers [46,160,161] and bulk heterojunction [6,[162][163][164][165][166] solar cells.…”

“…Depending on the thickness and optical constants of the individual layers, the interaction of a light source with a multilayer causes distict distributions of the electric field and energy absorption density [14]. Studies of electric field distribution in bilayer organic photovoltaic devices made of Zinc-Phthalocyanine (ZnPC), Perylene pigment (MPP) and other materials have been carried out [15]. If the polymer or PCBM domains get too big (as in the case of 80 wt% PCBM content), the exciton ionization efficiency is not optimal and if the domains are too small, the charge-transfer states will not separate and/or the charge transport to the electrodes is inhibited.…”

Materials are the heart and soul of photovoltaic devices. Based on the nature of materials, photovoltaics (solar cells) have been classified into various types. Based on its classifications many oxide and metallic materials are mainly used for photovoltaic applications. Device structure and nature of materials are very critical for the overall efficiency and performance of photovoltaics. However here in this particular review we will be only converging on the nature of various materials used to develop solar cells and their performances by using the materials of C, Cd, In doped Selenides and Telluride. Likewise the use of nanomaterials for biosensors based in thin film, particularly carbon based materials and its doping with selenides and telluride have attracted considerable attention due to provide a high surface-volume ratio, faster electron transfer and label-free responses. This review discussed these materials and its efficiencies.

“…If a photon reaches an interface, the probability is calculated whether the photon is transmitted through the interface or reflected. The light reflected at the interface is calculated based on Fresnel's equations by using the matrix material [16,17]. To simulate unpolarized light, the arithmetic mean of the reflection coefficients of TE and TM is calculated.…”

Comprehensive study on the light shielding potential of thermotropic layers for the development of new materials

In recent years thermotropic overheating protection glazings have been the focus for both solar thermal collector technology and architecture. A thermotropic glazing changes its light transmittance from highly transparent to light diffusing upon reaching a certain threshold temperature autonomously and reversibly. In thermotropic systems with fixed domains (TSFD) the scattering domains are embedded in a polymer matrix, which exhibits a sudden change of the refractive index upon reaching a threshold temperature. The aim of the present study was to comprehensively investigate the light shielding characteristics and potential of TSFD materials by applying simulation of light scattering in particle-filled layers. In random walk simulations a variety of parameters were varied systematically, and the effect on the light transmission behavior of TSFD was studied. The calculation steps of the simulation process are shown in detail. The simulations demonstrate that there is great potential for the production of functional materials with high overheating protection efficiency.
