A crucial step in the development of the next generation solar cells A team of KTU researchers has been synthesising and studying charge-transporting organic materials for several years. Previous experiments have focused more on molecules used for positive charge transfer in the perovskite solar cells.
An easy way to understand how a solar cell works is depicted in Fig. 7. Excited electron-hole pairs are created when light passes through a transparent electrode and is absorbed by the active substance (excitons). Many mechanisms can lead to the relaxation of exciton back to the ground state.
All these schemes are sometimes called “Third-generation” solar cells outside Europe or the “Full spectrum project” in Europe . They are mainly aiming to reduce the losses caused by non-utilization of sub-band-gap photons and using the longer and shorter wavelengths of the Sun’s spectrum, giving extra energy to the carriers.
High-efficiency solar cells are being developed using alternative, low-cost materials. Solar cells made of III-V multijunction materials and hybrid tandem III-V/Si solar cells are high-efficiency crystalline PVs that the National Renewable Energy Laboratory (NREL) is driving the development of (target efficiency of >30%).
A solar cell is made of semiconducting materials, such as p- and n-type silicon, with a layered p-n junction. When sunlight illuminates the panels, electrons are ejected from the semiconducting silicon.
The electrical energy generated by such a PV cell is now around 24% of the energy provided by the whole spectrum of our Sun . On the other hand, only 1.11 eV from the photon energy is utilized to produce an e-h pair in a Si solar cell.
