Solar cell new energy vehicle: maximum one-day range of 35km

On December 22, Toshiba announced that it has developed a new "transmission Cu2O solar cell" that can be installed directly on the outside of an electric car to charge the car under sunlight and provide a maximum one-day range of 35km (12.5km/kWh).

It is reported that transmission cuprous oxide solar cell is a kind of high efficiency series solar cell, the main material is copper and oxygen compound Cu2O, with low cost, light weight, high application value characteristics.

The scheme is characterized by the co-generation of two solar cell modules to improve the overall power generation efficiency. The transmission cuprous oxide solar cells are stacked on the high efficiency Si solar cells, and the overall power generation efficiency is improved to 27.4%.

According to Toshiba, solar cells mounted on the bonnet and roof of an electric car can provide up to 35 kilometers of battery life in a single day. It is worth mentioning that the battery, which is installed on the outside of the vehicle, requires higher protection to improve safety and durability.

Of course, since the battery life provided is not very large, the solar cell is only used as a way to supplement the power, to reduce the frequency of charging recharge. But for commuters who commute within 50km, this combination can also reduce the number of car charging.

In fact, the concept of solar energy has already been used in many industries. The optoelectronic semiconductor chip, which generates electricity directly from sunlight, can output voltage and generate current instantly if it meets certain illuminance conditions.

In the future, the application of solar energy in automobiles mainly has two aspects: "as a driving force" and "increase auxiliary energy". However, due to technical and cost reasons, solar cells are rarely applied in the automotive field. Toyota, Hyundai and GAC have applied related technologies before, but most of them provide energy for 12V vehicle power supply.

If Toshiba s research results are successful, the company will improve the energy network structure of new energy vehicles. Since solar cars do not burn fossil fuels, they do not emit harmful emissions, which could really reduce the use of "thermal power".
