Perovskite solar cells are solar cells that use perovskite-type organic metal halide semiconductors as light-absorbing materials. They belong to the third generation of solar cells and are also called new concept solar cells.

On January 13, Tianjin Zhonghuan Semiconductor Co., Ltd. (hereinafter referred to as "Zhonghuan Co., Ltd.") reached a share price of 33.17 yuan, and its total market value exceeded 100 billion yuan, reaching 100.6 billion yuan, becoming another 100 billion market value photovoltaic company, it is also the fifth photovoltaic-related company with a market value of over 100 billion yuan.

Diamond wire slicing technology The cutting process of crystalline silicon material accounts for a high proportion of non-silicon cost in the photovoltaic industry. Diamond wire cutting is a new technology of cutting processing, which is to fix the diamond wire by bonding and electroplating the diamond on the straight steel wire. Perform high speed round-trip cutting. The cost of the diamond wire slice is lower than that of the conventional mortar slice, and the cost of the mono crystal diamond wire slice is slightly lower than that of the polycrystalline diamond wire slice. At present, mono-c...

Classification of photovoltaic glass: Photovoltaic glass substrates for solar panels, generally including ultra-thin glass, surface-coated glass, low-iron (ultra-white) glass. Depending on the nature of the application and the method of manufacture, photovoltaic glass can be further divided into three types: the cover plate of a flat-type solar cell, generally a calendered glass; and the surface of the flat glass is plated with a semiconductor material usually having a thickness of only several micrometers, conductive substrate for thin film solar cells and lens or mirror type glass used in th...

Solar energy reaches the upper limit of the Earth’s atmosphere, about 1367W per square meter. The highest conversion efficiency of PV modules is about 21%, which means that the maximum power that can be produced in one square meter is 210W, but the remaining 1157W energy goes where? 1. Half of the energy is absorbed and reflected by the atmosphere. There are thousands of kilometers of atmosphere above the earth, divided into troposphere, stratosphere, intermediate layer, thermal layer and outer layer. About 30% of the sun’s energy is reflected into space, and about 19% of the energ...

Looking forward to 2019, the market demand for high-efficiency solar cell module products will continue to expand, and future technological advancement will remain the theme of industrial development. It is expected that the conversion efficiency of P-type PERC monocrystalline silicon and N-type PERT mono-crystal silicon photovoltaic cells will exceed 22%, and the power output of the mainstream solar panel will reach 310W or more; the ordinary photovoltaic cell technology will gradually be instead by high-efficiency solar cells using PERC technology. Half-chip, tile and other PV module technol...

Sunshine houses have entered the public’s field of vision in recent years, and more and more people have new needs to build sunny houses. If you want to build a sunny house, you must first choose the location of the house, take into account the time of the sunshine in the year, and pay attention to the shadow position of the trees and adjacent buildings. For example, the east or the south side is suitable as the flower room, the west room must consider the sunshade and ventilation, and the north room is suitable for the small office. Use the building’s terrace space to create a sol...

1. What is a solar cell? A: Solar cells are semiconductor devices that convert solar radiation directly into electrical energy based on the photovoltaic effect of semiconductors. Commercially available solar cells are mainly of the following types: monocrystalline silicon solar cells, polycrystalline silicon solar cells, amorphous silicon solar cells, and currently there are Cadmium tellurium cells, copper indium selenide cells, and nano titanium oxide sensitized cells etc. Crystalline silicon (single crystal, polycrystalline) solar cells require high purity silicon raw materials, generally re...

On November 12, 2018, the “OFweek 2018 (9th) China Solar Photovoltaic Summit Forum hosted by OFweek Solar Network, hosted by China’s high-tech industry portal OFweek, was held in Shenzhen. Photovoltaic elites from all over the country gathered in Shenzhen to actively interact with industry-recognized experts and business representatives to discuss the development of solar photovoltaic industry, market status, future technology trends and investment and financing opportunities. The atmosphere was lively and interactive. Professor Zeng Xiangbin from Huazhong University of Science and Tec...

It is reported that in the next month or more, the National Energy Administration will focus on accelerating the introduction of relevant policies for the photovoltaic industry in 2019 to provide guarantee for the stable development of the market. On November 2nd, at the time of the Wuxi New Energy Exhibition, when the friends of the PV circle met at the exhibition, the topic of sitting down and talking mainly focused on how the enterprise will transform and develop，how to find new opportunity, how to hold the group to warm up, and survive the industry winter in the post-5.31 policy era. At ...
