Researcher Joshua Pearce  from Michigan Technological University has been working on solving a long-standing problem in solar technology:

On one hand, solar thermalAims at transferring the radiation from the sun to thermal energy. Usually to warm up water. systems can harvest more energy in form of hot water than photovoltaicPhotovoltaics (PV) is the field of technology and research related to the application of solar cells for energy by converting sunlight directly into electricity. Solar power is sometimes used as a synonym to refer to electricity generated from solar radiation. systems can generate in terms of electricityElectricity generation includes all technologies that turn some form of energy into useful electric energy. Electricity is a form of energy that has magnetic, radiant and chemical effects. Electric current is created by a flow of electrons., but electric powerElectricity generation includes all technologies that turn some form of energy into useful electric energy. Electricity is a form of energy that has magnetic, radiant and chemical effects. Electric current is created by a flow of electrons. is valued higher in monetary terms. Yet the average household (and industry) needs both.

Up to now, a choice had to made as to which technology was chosen for roof space, but this new solar photovoltaic thermal energy system (PVT) works with a  different kind of silicon compared to earlier such models, and efficiencyUsing less energy/electricity to perform the same function. Programs designed to use electricity more efficiently - doing the same with less. has been greatly increased. This new cells is incorporating thin-film silicon in a new type of PVT which seems to overcome many of the previously encountered problems.photovoltaic.gif

Pearce has published two articles on this research,  “The Effect of Hybrid Photovoltaic Thermal Device Operating Conditions on Intrinsic Layer Thickness Optimization of Hydrogenated Amorphous Silicon Solar Cells,” in the journal Solar Energy, coauthored with Pathak, Girotra and S. J. Harrison;  and “Effects on Amorphous Silicon Photovoltaic Performance from High-Temperature Annealing Pulses in Photovoltaic Thermal Hybrid Devices” in the journal Solar Energy Materials and Solar CellsA solar cell transforms sunlight directly into electrical energy.A solar cell or photovoltaic cell is a wide area electronic device that converts solar energy into electricity by the photovoltaic effect.
