Herein, we provide a solar energy system co-generating H2 and electricity in a cascade-like conversion of the concentrated sunlight. Matching the energy grade between the solar spectrum and the conversions, the system uses not only the UV-vis/IR band for photo-thermal H2 but also the Vis and near-infrared (NIR) band for PV electricity.

The high concentration of sunlight achieved with multijunction cells requires more sophisticated cooling and tracking systems, which can potentially result in higher energy costs. The cost effectiveness of CPV technology is related to the fact that much smaller sized solar cells are used to convert the concentrated light, which means that
Solar power, also known as solar electricity, is the conversion of energy from sunlight into electricity, either directly using photovoltaics (PV) or indirectly using concentrated solar power.

Concentrated solar power uses software-powered mirrors to concentrate the sun''s thermal energy and direct it towards receivers which heat up and power steam turbines or engines that produce electricity. Some CSP plants can take that energy and store it for when irradiance levels are low. This is why concentrated solar power is a viable utility
CSP technologies use mirrors to reflect and concentrate sunlight onto a receiver. The energy from the concentrated sunlight heats a high temperature fluid in the receiver. This heat - also known as thermal energy - can be used to spin a turbine or power an engine to generate electricity. It can also be used in a variety of industrial
Solar power is a form of energy conversion in which sunlight is used to generate electricity. Virtually nonpolluting and abundantly available, solar power stands in stark contrast to the combustion of fossil fuel and has become increasingly attractive to individuals, businesses, and governments on the path to sustainability.
Any solar cell technology must be evaluated and, as a result, optimized using the concentration of suns and solar energy absorbed. The concentrated photovoltaic (CPV) method concentrates and ultimately multiplies the captured sunlight using reasonably priced optical materials and objects [40]. The general behavior of focusing sunlight over a
This increase in the concentration of solar radiation on the small area of solar cells yields a significant increase in the photovoltaics cell temperature that ultimately increases the chance of failures and reduces the system conversion efficiency. Ahmadi et al. studied different solar energy techniques for electricity generation.

It was discussed that concentrated photovoltaic uses optical devices, mirrors, or lenses along with tracking system to focus sunlight into a small area of PV cell. Due to the high intensity of sunlight, the temperature of the system increases more and more, resulting the reduction of system overall efficiency.
