A Novel Modeling of Quantum Dot Sensitized Solar Cells

Abstract

The electrical properties of quantum dot sensitized solar cells (QDSSC) under illumination and dark conditions are investigated and the measurements obtained on the cells are compared with theoretical calculations. Curve fitting are solved with the help of non-linear curve least squares solver in MATLAB. The parameter matrix P was then fitted using the solver to minimize the mean square of deviation between the experimental and fitted data. Thus obtained parameters are used for modeling the solar cell in SIMULINK environment. This model is a phenomenological model to fit I–V characteristics of real cells.

Potential biocontrol of Echinochloa crus-galli (Barnyard grass) by Curvularia lunata LD2 as a Mycoherbicide

“…Mycoherbicides are fungal pathogens that are applied for the sole purpose to control a population of weeds [13,14]. Microbial preparation of herbicide is defined as bioherbicides that can control the weed [15,16].…”

Anti Bacterial Activity of Dashapushpa Ghritham

“…Linnv, Ipomoea sepiaria Roxb., Vernonia cinerea L [10,11,12,13,14]. They have various medicinal properties including anti-diabetic, anti-cancer, anti-tumor, hepatoprotective, immunomodulatory, anti-diarrheal, anti-helminthic, anti-inflammatory, antioxidant and anti-microbial activity [15,16,17,18].The different properties of dashapushpam plants are shown in table 1 [19,20,21,22].The present study is to investigate the anti bacterial activity of these plants extract and the drug dashapushpa ghritham when tested against gram positive and gram negative bacteria [23,24,25]. Dashapushpa ghritham is a drug formulation from an ancient ayurvedic text "visha vaidhya jyostnika".…”
