TL;DR: In this article, the performance of double slope solar stills was evaluated in terms of recorded temperatures, instantaneous and internal thermal efficiencies and system productivity, and the experimental results revealed that active solar still maximizes both fresh water productivity (10.06l/m2·day) as well as internal thermal efficiency (80.6%) compared with passive solar still (7.8 l/m 2·day productivity and 57.1% internal efficiency) under conditions of 1 cm basin brine depth and 3mm glass cover thickness.

TL;DR: This review intends to discuss the underlying concepts of photovoltaics and thermoelectrics and summarizes the current research accomplishments and the various approaches used to optimize hybrid photvoltaic/thermoelectric systems.
Abstract: Development of renewable energies, particularly solar energy, is crucial for meeting future energy needs. Solar light and thermal energy can provide sufficient electricity needed in daily life. In this pursuit, photovoltaics and thermoelectrics have been developing for energy conversion. While photovoltaics mainly convert the UV and visible regions of the solar spectrum, thermoelectrics utilize the IR region. Combining the photovoltaic and thermoelectric effects can extend the effective spectrum range. In recent years, there have been studies on hybrid photovoltaic/thermoelectric systems toward improved conversion efficiency. This review intends to discuss the underlying concepts of photovoltaics and thermoelectrics and summarizes the current research accomplishments and the various approaches used to optimize hybrid photovoltaic/thermoelectric systems. As such, this review encourages further research into hybrid generators due to the promising results achieved. Future prospects and suggestions of potential approaches for further development of these generators are also discussed.

TL;DR: In this paper, a hybrid tandem photovoltaic (HTPV) architecture is proposed to achieve power conversion efficiencies above 20% in order to keep installation costs down.
Abstract: It is estimated that for photovoltaics to reach grid parity around the planet, they must be made with costs under $0.50 per Wp and must also achieve power conversion efficiencies above 20% in order to keep installation costs down. In this work we explore a novel solar cell architecture, a hybrid tandem photovoltaic (HTPV), and show that it is capable of meeting these targets. HTPV is composed of an inexpensive and low temperature processed solar cell, such as an organic or dye-sensitized solar cell, that can be printed on top of one of a variety of more traditional inorganic solar cells. Our modeling shows that an organic solar cell may be added on top of a commercial CIGS cell to improve its efficiency from 15.1% to 21.4%, thereby reducing the cost of the modules by ∼15% to 20% and the cost of installation by up to 30%. This suggests that HTPV is a promising option for producing solar power that matches the cost of existing grid energy.

TL;DR: In this article, the state-of-the-art research of photo-rechargeable batteries based on organic solar cells, as well as storage modules, is reviewed, where high efficiencies can be achieved by the combination of dye-sensitized solar cells (DSSC) and capacitors.
Abstract: The global energy demand is increasing at the same time as fossil fuel resources are dwindling. Consequently, the search for alternative energy sources is a major topic worldwide. Solar energy is one of the most promising, effective and emission-free energy sources. However, the energy has to be stored to compensate the fluctuating availability of the sun and the actual energy demand. Photo-rechargeable electric energy storage systems may solve this problem by immediately storing the generated electricity. Different combinations of solar cells and storage devices are possible. High efficiencies can be achieved by the combination of dye-sensitized solar cells (DSSC) and capacitors. However, other hybrid devices including DSSCs or organic photovoltaic systems and redox flow batteries, lithium ion batteries and metal air batteries are playing an increasing role in this research field. This Progress Report reviews the state of the art research of photo-rechargeable batteries based on organic solar cells, as well as storage modules.
