Photovoltaic Prickle Pear Harvesting Tool
Mexico is the largest cactus exporter of the world and 40% of the production cost is provided from the harvest operation. Many workers are required to operate daily and suffer wrist pain after two weeks of collecting pears with mechanical pruners. A motor driven tool supplied from a photovoltaic system was employed for harvesting; different blades were tested at different cutting speeds. It was...
متن کاملIR light harvesting with silicon microspheres - application to photovoltaic devices
Single-junction photovoltaic devices suffer from intrinsic obstacles limiting their efficiency to a top value dictated by the well-known Shockley–Queisser (SQ) limit [1]. The most fundamental limitation is given by the energy bandgap of the semiconductor, which determines the minimum energy of photons that can be converted into electron-hole pairs. In the case of silicon a large percentage of i...
متن کاملAutonomous Temperature Sensor Based on a Photovoltaic Energy Harvesting System
In this paper we present an autonomous temperature sensor supplied by a on chip photovoltaic energy harvester. Then system is realized in a BCD SOI technology. The energy harvesting elements consist of a 34 trench-insulated p-n junctions, while the sensing system consists of a bandgap reference circuit, including an integrated high precision temperature sensor, and a high voltage low drop-out v...
متن کاملA PbS nanocrystal-C60 photovoltaic device for infrared light harvesting
PbS nanocrystal nc-PbS -C60 photovoltaic devices are demonstrated, in which nc-PbS function as electron donors, showing infrared photosensitivity up to 1600 nm. Annealing nc-PbS is proved to remove capping oleic acid ligands, studied using x-ray photoelectron spectroscopy, significantly improving the short circuit current, open circuit voltage, and fill factor. The device performance is rationa...
متن کاملEfficient tool flow for 3D photovoltaic modelling
Performance predictions and optimisation strategies in current nanotechnology-based photovoltaic (PV) require simulation tools that can efficiently and accurately compute optical and electrical performance parameters of intricate 3D geometrical structures. Due to the complexity of each type of simulation it is often the case that a single package excels in either optical or electrical modelling...
