Researchers from the United States have proposed a new electrode design for fractal solar panels that combines the typical aesthetic advantages of the technology with the efficiency of busbar design. The proposed pattern is based on the fractal tree structure known as H tree, or T-branching, which is a geometric shape consisting of a repeating pattern that resembles the letter H. The hybrid H-tree/busbar pattern showed power losses that are close to those of standard busbars.

The Chinese manufacturer shipped 14.3 GW of PV modules last year, up 2.9 GW from 2018. In its 2020 outlook, it reiterated its initial shipment guidance and confirmed its plans to ramp up capacity.

Italian company Ecoprogetti will supply the production equipment to Bahrain-based module producer Solartecc. Output is set to begin in the third quarter.

The electricity company wants a solar module fab at its Tana Power Station in Murang’a county. The factory would have an initial annual production capacity of 10 MW.

Soluxtec is almost trebling output capacity at its 200 MW fab in the Eifel region. The Luxembourg-owned manufacturer says it wants production capacity of 550 MW for monocrystalline PERC modules and special formats this year.

A U.S. research team has discovered that backsheets are most affected by cracking and degradation on inner layers, as such areas tend to become more rigid. The scientists have also discovered that degradation is accelerated by chemicals descending from the solar cells’ EVA encapsulant to the backsheets themselves.

The new n-type panels, which offer 405 W of power output and an efficiency rate of 21.22%, are designed for the residential PV segment.

The device is based on a state-feedback adaptive control system in a real-time controller. According to its developers, it can achieve good dynamic response and boasts better bandwidth than current commercial alternatives.

Solar module manufacturers should begin testing new technologies in higher-value niche markets, say scientists at the U.S. institution. For example, bringing perovskite technology directly to the mainstream market remains prohibitive in terms of initial investment but segments such as building-integrated PV or microelectronics devices may offer better routes to commercial maturity.

Researchers from Hungary have analyzed the thermal behavior of different types of PV module via thermography, and claim to have shown that theoretical models are insufficient to measure the maximum, minimum, and average temperatures of the panels. According to their analysis, glass-glass modules without frame showed the highest temperatures, while the lowest temperatures were measured for polycrystalline glass-backsheet panels with frame.
