The rapid development of photovoltaic plays an important role in achieving the carbon-neutral goal. How to improve the conversion efficiency and power generation of solar photovoltaic has always been a focus issue. However, more attention is paid to the impact of photovoltaic panel working temperature on the performance of photovoltaic power generation, and how air temperature affects photovoltaic power generation has been ignored. This paper compared and analyzed the impact of the difference in air temperature between lake and land on the revenue of photovoltaic power generation, and established the functional equation between photovoltaic power generation, air temperature and solar radiation, and revealed the relationship between air temperature, solar radiation and photovoltaic power generation.

In this paper, Quantum Corrected (QMC) horizontally doped Si/4H-SiC multi layers avalanche photo sensor (APS) has been developed for application in bio-medical domain. The photo electric characteristics of the developed photo sensor has been analysed in terms of photo current, photo responsivity and quantum efficiency in 300nm – 900nm wavelength region. These all parameters have been improved considerably by incorporating Si/4H-SiC multi layers structure into the active region of the devices. Recently demand of such bio-medical photo-sensors is increasing significantly for identification of anti-bodies and virus in human blood. The validity of newly developed model has been established by comparing the simulated result with the reported experimental data. The photo electrical characteristics analysis of the designed QMC model-based Si/4H-SiC multi layers avalanche photo sensor depict that the photo current is ~20μA whereas the photo responsivity and quantum efficiency are ~0.65A/Wand ~0.67 respectively. The results clearly establish the superiority of proposed photo-sensor for developing medical instruments in visible wavelength region (300nm – 900nm).

Phototheranostics represents a highly promising paradigm for cancer therapy, although selecting an appropriate optical imager for clinical use remains challenging. We evaluated the phototheranostic nanoparticle-related properties of liposomally formulated phospholipid-conjugated indocyanine green, denoted as LP-iDOPE, for cancer diagnosis and treatment using photobiomodulation with a near-infrared (NIR)-light emitting diode (LED) light irradiator. Using in vivo NIR fluorescence imaging, we demonstrated that LP-iDOPE was selectively delivered to tumor sites with high accumulation and a long half-life. Following NIR-LED light irradiation of the tumor region of LP-iDOPE accumulation, effector CD8+ T cells were activated at the secondary lymphoid organs, migrated, and subsequently released cytokines including interferon-γ and tumor necrosis factor-α, resulting in effective tumor regression. Our cancer immunotherapy strategy using LP-iDOPE as a phototheranostic nanoparticle and an NIR-LED light irradiator as a photobiomodulation device represents a promising approach to noninvasive cancer therapy.

We found that the S4 thickness will differ for designing of the structure based on either of resonance peaks of MoS2 monolayer. Based on three resonance peaks of MoS2, three structures designed for S4 and their absorption for normal incidence based on transfer matrix method are calculated.

To acquire visible emissions using near-ultraviolet (NUV) and near-infrared (NIR) irradiations for multiple solid state lighting and display applications, exploring efficient upconversion (UC)/downconversion (DC) mode of erbium ion in different matrixes is of great importance. Here, we aimed to originally study the dual emission mode of borophosphate La7O6(BO3)(PO4)2 (LBP)-based solid solution doped with erbium ion. Er3+ occupies the lattice site of La3+ . A yellowish-green light is acquired by both DC and UC. It is identified that the UC photoluminescence has lower correlated color temperature (5694 K), higher color purity (87%), and longer lifetime (0.338 ms) than the DC. The present research can provide a new insight into the design and UC/DC photoluminescence of borophosphate-based solid solution fabricated by erbium for expanding solid state lighting applications.
