2 天之前· In the past three years, Longi has broken the cell efficiency record 18 times in a row. Today, the company holds two cell efficiency world records, 34.6 percent for crystalline silicon-perovskite tandem solar cells, and 27.30 percent for crystalline silicon heterojunction back …
Despite the growth, the production costs of the first generation PV solar cells are high, i.e., US$200–500/m 2, and there is a further decline until US$150/m 2 as the amount of material needed and procedures used are just more than half the cost .
The study includes four generations of the solar PV cells from their beginning of journey to the advancements in their performance till date. During past few decades, many new emerging materials came out as an effective source for the production of electrical energy to meet the future demands with cost effectiveness as well.
The Si-layer for the solar cell can be detached from the wafer due to the mechanically fragile separation layer underneath . The Institute of Physical Electronics also relies on the epitaxial growth of the active Si-layer on a so-called quasi-monocrystalline Si-film.
Photovoltaic (PV) solar cells are in high demand as they are environmental friendly, sustainable, and renewable sources of energy. The PV solar cells have great potential to dominate the energy sector. Therefore, a continuous development is required to improve their efficiency.
A complication, however, arises from the fact that each subcell has to generate the same electric current in the case of the conventional two-terminal devices. Prominent examples of these tandem or multijunction solar cells are the a-Si/SiGe and the GaInP/GaAs/Ge technologies, the latter being used in space applications.
However, the silicon-based PV solar cells were further refined by the beginning of the twentieth century, and the PV solar cell with an efficiency of 24% was produced . Less than a decade later, scientists developed silicon solar cells with an increased electricity return rate by applying space-age materials .
