(c) (d) Photovoltaic solar cells tap into sunlight—the most abundant renewable energy source on the Earth—for electricity. Our planet receives ~1.2×1017 W of solar power, while the rate of current worldwide energy consumption is ~10,000 times smaller at ~1.3×1013 W.1 This means that the Earth receives more solar energy in an hour than the total energy it consumes in an entire year. Solar energy...

In the past year we focused on developing the metal nanostructure simulation, nanowire growth, and device fabrication. We explored a new geometry with Hertzianlike disc shaped antennas to replace the bowtie antennas we had initially investigated to achieve better performance. Light absorption enhancement of the nanodimers in terms of size and inter space was simulated. A testbed structure based...

Inorganic/organic hybrid solar cells have attracted a lot of interest due to their potential in combining the advantages of both components. To understand the key issues in association with photoinduced charge separation/transportation processes and to improve overall power conversion efficiency, various combinations with nanostructures of hybrid systems have been investigated. Here, we briefly...

As solar energy costs continue to drop, the number of large-scale deployment projects increases, and the need for different analysis models for photovoltaic (PV) modules in both academia and industry rises. This paper proposes a modified equivalent-circuit model for PV modules. A PV module comprises several series-connected PV cells, to generate more electrical power, where each PV cell has an ...

Organolead trihalide perovskite (OTP) materials are emerging as naturally abundant materials for low-cost, solution-processed and highly efficient solar cells. Here, we show that, in OTP-based photovoltaic devices with vertical and lateral cell configurations, the photocurrent direction can be switched repeatedly by applying a small electric field of <1 V μm(-1). The switchable photocurrent, ge...

Hybrid thin film solar cell based on all-inorganic nanoparticles is a new member in the family of photovoltaic devices. In this work, a novel and performance-efficient inorganic hybrid nanostructure with continuous charge transportation and collection channels is demonstrated by introducing CdTe nanotetropods (NTs) and CdSe quantum dots (QDs). Hybrid morphology is characterized, demonstrating a...

This article provides a classification of high efficiency switching power-gyrator structures and their use as cells for energy processing in photovoltaic solar facilities. Having into account the properties of these topologies presented in the article, their inclusion in solar facilities allows increasing the performance of the whole installation. Thus, the design, simulation and implementation...
