Keeping track of the rapidly improving solar cell performance is not as easy as it might seem. Martin Green describes the Solar Cell Efficiency Tables that have been providing 6-monthly updates of record solar cell performance since the 1990s. Keeping track of the rapidly improving solar cell ...
to locate the specific position of the sun, drive a motor to act and adjust the solar-cell panel toward the irradiating direction of the sunlight, therefore, the solar-cell panel tracking controller plays the roles of increasing the absorbed sunlight energy and improving the conversion efficiency....

A Hybrid Dual-Axis Solar Tracking System: Combining Light-Sensing and Time-Based GPS for Optimal Energy Efficiency Fixed solar panels face significant energy loss as they cannot consistently capture optimal sunlight. Because of that, the overall efficiency of the PV pan... Shehab Ahmed - Energies...
There exist two main problems when operating a PV generation system – the conversion efficiency is very low, especially under low irradiation, and the amount of the electric power generated by solar cells varies with weather conditions, i.e., the solar insolation and panel temperature. To ...

Singlet fission sensitized solar cells are expected to display a greatly enhanced power conversion efficiency compared to conventional single-junction cells, but the efficient design of such devices relies on the selection of materials capable of harvesting triplets generated in the fission chromophore. ...
Prospects for concentrating photovoltaic (CPV) power are growing as the market increasingly values high power conversion efficiency to leverage now-dominant balance of system and soft costs. This trend is particularly acute for rooftop photovoltaic power, where delivering the high efficiency of ...
We report on both intrinsic and extrinsic stability of formamidinium lead bromide [CH(NH2)2PbBr3=FAPbBr3] perovskite solar cell that yield a high photovoltage. The fabrication of FAPbBr3 devices displaying an outstanding photovoltage of 1.53 V and a power conversion efficiency of over 8% was rea...
